The Adventure of the Bruce-Partington Plans

In the third week of November, in the year 1895, a dense yellow fog settled down upon London. From the Monday to the Thursday I doubt whether it was ever possible from our windows in Baker Street to see the loom of the opposite houses. The first day Holmes had spent in cross-indexing his huge book of references. The second and third had been patiently occupied upon a subject which he had recently made his hobby—the music of the Middle Ages. But when, for the fourth time, after pushing back our chairs from breakfast we saw the greasy, heavy brown swirl still drifting past us and condensing in oily drops upon the window-panes, my comrade’s impatient and active nature could endure this drab existence no longer. He paced restlessly about our sitting-room in a fever of suppressed energy, biting his nails, tapping the furniture, and chafing against inaction.

“Nothing of interest in the paper, Watson?” he said.

I was aware that by anything of interest, Holmes meant anything of criminal interest. There was the news of a revolution, of a possible war, and of an impending change of government; but these did not come within the horizon of my companion. I could see nothing recorded in the shape of crime which was not commonplace and futile. Holmes groaned and resumed his restless meanderings.

“The London criminal is certainly a dull fellow,” said he in the querulous voice of the sportsman whose game has failed him. “Look out this window, Watson. See how the figures loom up, are dimly seen, and then blend once more into the cloud-bank. The thief or the murderer could roam London on such a day as the tiger does the jungle, unseen until he pounces, and then evident only to his victim.”

“There have,” said I, “been numerous petty thefts.”

Holmes snorted his contempt.

“This great and sombre stage is set for something more worthy than that,” said he. “It is fortunate for this community that I am not a criminal.”

“It is, indeed!” said I heartily.

“Suppose that I were Brooks or Woodhouse, or any of the fifty men who have good reason for taking my life, how long could I survive against my own pursuit? A summons, a bogus appointment, and all would be over. It is well they don’t have days of fog in the Latin countries—the countries of assassination. By Jove! here comes something at last to break our dead monotony.”

It was the maid with a telegram. Holmes tore it open and burst out laughing.

“Well, well! What next?” said he. “Brother Mycroft is coming round.”

“Why not?” I asked.

“Why not? It is as if you met a tram-car coming down a country lane. Mycroft has his rails and he runs on them. His Pall Mall lodgings, the Diogenes Club, Whitehall—that is his cycle. Once, and only once, he has been here. What upheaval can possibly have derailed him?”

“Does he not explain?”

Holmes handed me his brother’s telegram.

“Cadogan West? I have heard the name.”

“It recalls nothing to my mind. But that Mycroft should break out in this erratic fashion! A planet might as well leave its orbit. By the way, do you know what Mycroft is?”

I had some vague recollection of an explanation at the time of the Adventure of the Greek Interpreter.

“You told me that he had some small office under the British government.”

Holmes chuckled.

“I did not know you quite so well in those days. One has to be discreet when one talks of high matters of state. You are right in thinking that he is under the British government. You would also be right in a sense if you said that occasionally he is the British government.”

“My dear Holmes!”

“I thought I might surprise you. Mycroft draws four hundred and fifty pounds a year, remains a subordinate, has no ambitions of any kind, will receive neither honour nor title, but remains the most indispensable man in the country.”

“But how?”

“Well, his position is unique. He has made it for himself. There has never been anything like it before, nor will be again. He has the tidiest and most orderly brain, with the greatest capacity for storing facts, of any man living. The same great powers which I have turned to the detection of crime he has used for this particular business. The conclusions of every department are passed to him, and he is the central exchange, the clearinghouse, which makes out the balance. All other men are specialists, but his specialism is omniscience. We will suppose that a minister needs information as to a point which involves the Navy, India, Canada and the bimetallic question; he could get his separate advices from various departments upon each, but only Mycroft can focus them all, and say offhand how each factor would affect the other. They began by using him as a short-cut, a convenience; now he has made himself an essential. In that great brain of his everything is pigeon-holed and can be handed out in an instant. Again and again his word has decided the national policy. He lives in it. He thinks of nothing else save when, as an intellectual exercise, he unbends if I call upon him and ask him to advise me on one of my little problems. But Jupiter is descending to-day. What on earth can it mean? Who is Cadogan West, and what is he to Mycroft?”

“I have it,” I cried, and plunged among the litter of papers upon the sofa. “Yes, yes, here he is, sure enough! Cadogan West was the young man who was found dead on the Underground on Tuesday morning.”

Holmes sat up at attention, his pipe halfway to his lips.

“This must be serious, Watson. A death which has caused my brother to alter his habits can be no ordinary one. What in the world can he have to do with it? The case was featureless as I remember it. The young man had apparently fallen out of the train and killed himself. He had not been robbed, and there was no particular reason to suspect violence. Is that not so?”

“There has been an inquest,” said I, “and a good many fresh facts have come out. Looked at more closely, I should certainly say that it was a curious case.”

“Judging by its effect upon my brother, I should think it must be a most extraordinary one.” He snuggled down in his armchair. “Now, Watson, let us have the facts.”

“The man’s name was Arthur Cadogan West. He was twenty-seven years of age, unmarried, and a clerk at Woolwich Arsenal.”

“Government employ. Behold the link with Brother Mycroft!”

“He left Woolwich suddenly on Monday night. Was last seen by his fiancée, Miss Violet Westbury, whom he left abruptly in the fog about 7:30 that evening. There was no quarrel between them and she can give no motive for his action. The next thing heard of him was when his dead body was discovered by a plate-layer named Mason, just outside Aldgate Station on the Underground system in London.”

“When?”

“The body was found at six on Tuesday morning. It was lying wide of the metals upon the left hand of the track as one goes eastward, at a point close to the station, where the line emerges from the tunnel in which it runs. The head was badly crushed—an injury which might well have been caused by a fall from the train. The body could only have come on the line in that way. Had it been carried down from any neighbouring street, it must have passed the station barriers, where a collector is always standing. This point seems absolutely certain.”

“Very good. The case is definite enough. The man, dead or alive, either fell or was precipitated from a train. So much is clear to me. Continue.”

“The trains which traverse the lines of rail beside which the body was found are those which run from west to east, some being purely Metropolitan, and some from Willesden and outlying junctions. It can be stated for certain that this young man, when he met his death, was travelling in this direction at some late hour of the night, but at what point he entered the train it is impossible to state.”

“His ticket, of course, would show that.”

“There was no ticket in his pockets.”

“No ticket! Dear me, Watson, this is really very singular. According to my experience it is not possible to reach the platform of a Metropolitan train without exhibiting one’s ticket. Presumably, then, the young man had one. Was it taken from him in order to conceal the station from which he came? It is possible. Or did he drop it in the carriage? That is also possible. But the point is of curious interest. I understand that there was no sign of robbery?”

“Apparently not. There is a list here of his possessions. His purse contained two pounds fifteen. He had also a check-book on the Woolwich branch of the Capital and Counties Bank. Through this his identity was established. There were also two dress-circle tickets for the Woolwich Theatre, dated for that very evening. Also a small packet of technical papers.”

Holmes gave an exclamation of satisfaction.

“There we have it at last, Watson! British government—Woolwich. Arsenal—technical papers—Brother Mycroft, the chain is complete. But here he comes, if I am not mistaken, to speak for himself.”

A moment later the tall and portly form of Mycroft Holmes was ushered into the room. Heavily built and massive, there was a suggestion of uncouth physical inertia in the figure, but above this unwieldy frame there was perched a head so masterful in its brow, so alert in its steel-grey, deep-set eyes, so firm in its lips, and so subtle in its play of expression, that after the first glance one forgot the gross body and remembered only the dominant mind.

At his heels came our old friend Lestrade, of Scotland Yard—thin and austere. The gravity of both their faces foretold some weighty quest. The detective shook hands without a word. Mycroft Holmes struggled out of his overcoat and subsided into an armchair.

“A most annoying business, Sherlock,” said he. “I extremely dislike altering my habits, but the powers that be would take no denial. In the present state of Siam it is most awkward that I should be away from the office. But it is a real crisis. I have never seen the Prime Minister so upset. As to the Admiralty—it is buzzing like an overturned bee-hive. Have you read up the case?”

“We have just done so. What were the technical papers?”

“Ah, there’s the point! Fortunately, it has not come out. The press would be furious if it did. The papers which this wretched youth had in his pocket were the plans of the Bruce-Partington submarine.”

Mycroft Holmes spoke with a solemnity which showed his sense of the importance of the subject. His brother and I sat expectant.

“Surely you have heard of it? I thought everyone had heard of it.”

“Only as a name.”

“Its importance can hardly be exaggerated. It has been the most jealously guarded of all government secrets. You may take it from me that naval warfare becomes impossible within the radius of a Bruce-Partington’s operation. Two years ago a very large sum was smuggled through the Estimates and was expended in acquiring a monopoly of the invention. Every effort has been made to keep the secret. The plans, which are exceedingly intricate, comprising some thirty separate patents, each essential to the working of the whole, are kept in an elaborate safe in a confidential office adjoining the arsenal, with burglar-proof doors and windows. Under no conceivable circumstances were the plans to be taken from the office. If the chief constructor of the Navy desired to consult them, even he was forced to go to the Woolwich office for the purpose. And yet here we find them in the pocket of a dead junior clerk in the heart of London. From an official point of view it’s simply awful.”

“But you have recovered them?”

“No, Sherlock, no! That’s the pinch. We have not. Ten papers were taken from Woolwich. There were seven in the pocket of Cadogan West. The three most essential are gone—stolen, vanished. You must drop everything, Sherlock. Never mind your usual petty puzzles of the police-court. It’s a vital international problem that you have to solve. Why did Cadogan West take the papers, where are the missing ones, how did he die, how came his body where it was found, how can the evil be set right? Find an answer to all these questions, and you will have done good service for your country.”

“Why do you not solve it yourself, Mycroft? You can see as far as I.”

“Possibly, Sherlock. But it is a question of getting details. Give me your details, and from an armchair I will return you an excellent expert opinion. But to run here and run there, to cross-question railway guards, and lie on my face with a lens to my eye—it is not my metier. No, you are the one man who can clear the matter up. If you have a fancy to see your name in the next honours list—”

My friend smiled and shook his head.

“I play the game for the game’s own sake,” said he. “But the problem certainly presents some points of interest, and I shall be very pleased to look into it. Some more facts, please.”

“I have jotted down the more essential ones upon this sheet of paper, together with a few addresses which you will find of service. The actual official guardian of the papers is the famous government expert, Sir James Walter, whose decorations and sub-titles fill two lines of a book of reference. He has grown grey in the service, is a gentleman, a favoured guest in the most exalted houses, and, above all, a man whose patriotism is beyond suspicion. He is one of two who have a key of the safe. I may add that the papers were undoubtedly in the office during working hours on Monday, and that Sir James left for London about three o’clock taking his key with him. He was at the house of Admiral Sinclair at Barclay Square during the whole of the evening when this incident occurred.”

“Has the fact been verified?”

“Yes; his brother, Colonel Valentine Walter, has testified to his departure from Woolwich, and Admiral Sinclair to his arrival in London; so Sir James is no longer a direct factor in the problem.”

“Who was the other man with a key?”

“The senior clerk and draughtsman, Mr. Sidney Johnson. He is a man of forty, married, with five children. He is a silent, morose man, but he has, on the whole, an excellent record in the public service. He is unpopular with his colleagues, but a hard worker. According to his own account, corroborated only by the word of his wife, he was at home the whole of Monday evening after office hours, and his key has never left the watch-chain upon which it hangs.”

“Tell us about Cadogan West.”

“He has been ten years in the service and has done good work. He has the reputation of being hot-headed and imperious, but a straight, honest man. We have nothing against him. He was next Sidney Johnson in the office. His duties brought him into daily, personal contact with the plans. No one else had the handling of them.”

“Who locked up the plans that night?”

“Mr. Sidney Johnson, the senior clerk.”

“Well, it is surely perfectly clear who took them away. They are actually found upon the person of this junior clerk, Cadogan West. That seems final, does it not?”

“It does, Sherlock, and yet it leaves so much unexplained. In the first place, why did he take them?”

“I presume they were of value?”

“He could have got several thousands for them very easily.”

“Can you suggest any possible motive for taking the papers to London except to sell them?”

“No, I cannot.”

“Then we must take that as our working hypothesis. Young West took the papers. Now this could only be done by having a false key—”

“Several false keys. He had to open the building and the room.”

“He had, then, several false keys. He took the papers to London to sell the secret, intending, no doubt, to have the plans themselves back in the safe next morning before they were missed. While in London on this treasonable mission he met his end.”

“How?”

“We will suppose that he was travelling back to Woolwich when he was killed and thrown out of the compartment.”

“Aldgate, where the body was found, is considerably past the station London Bridge, which would be his route to Woolwich.”

“Many circumstances could be imagined under which he would pass London Bridge. There was someone in the carriage, for example, with whom he was having an absorbing interview. This interview led to a violent scene in which he lost his life. Possibly he tried to leave the carriage, fell out on the line, and so met his end. The other closed the door. There was a thick fog, and nothing could be seen.”

“No better explanation can be given with our present knowledge; and yet consider, Sherlock, how much you leave untouched. We will suppose, for argument’s sake, that young Cadogan West had determined to convey these papers to London. He would naturally have made an appointment with the foreign agent and kept his evening clear. Instead of that he took two tickets for the theatre, escorted his fiancée halfway there, and then suddenly disappeared.”

“A blind,” said Lestrade, who had sat listening with some impatience to the conversation.

“A very singular one. That is objection No. 1. Objection No. 2: We will suppose that he reaches London and sees the foreign agent. He must bring back the papers before morning or the loss will be discovered. He took away ten. Only seven were in his pocket. What had become of the other three? He certainly would not leave them of his own free will. Then, again, where is the price of his treason? One would have expected to find a large sum of money in his pocket.”

“It seems to me perfectly clear,” said Lestrade. “I have no doubt at all as to what occurred. He took the papers to sell them. He saw the agent. They could not agree as to price. He started home again, but the agent went with him. In the train the agent murdered him, took the more essential papers, and threw his body from the carriage. That would account for everything, would it not?”

“Why had he no ticket?”

“The ticket would have shown which station was nearest the agent’s house. Therefore he took it from the murdered man’s pocket.”

“Good, Lestrade, very good,” said Holmes. “Your theory holds together. But if this is true, then the case is at an end. On the one hand, the traitor is dead. On the other, the plans of the Bruce-Partington submarine are presumably already on the Continent. What is there for us to do?”

“To act, Sherlock—to act!” cried Mycroft, springing to his feet. “All my instincts are against this explanation. Use your powers! Go to the scene of the crime! See the people concerned! Leave no stone unturned! In all your career you have never had so great a chance of serving your country.”

“Well, well!” said Holmes, shrugging his shoulders. “Come, Watson! And you, Lestrade, could you favour us with your company for an hour or two? We will begin our investigation by a visit to Aldgate Station. Good-bye, Mycroft. I shall let you have a report before evening, but I warn you in advance that you have little to expect.”

An hour later Holmes, Lestrade and I stood upon the Underground railroad at the point where it emerges from the tunnel immediately before Aldgate Station. A courteous red-faced old gentleman represented the railway company.

“This is where the young man’s body lay,” said he, indicating a spot about three feet from the metals. “It could not have fallen from above, for these, as you see, are all blank walls. Therefore, it could only have come from a train, and that train, so far as we can trace it, must have passed about midnight on Monday.”

“Have the carriages been examined for any sign of violence?”

“There are no such signs, and no ticket has been found.”

“No record of a door being found open?”

“None.”

“We have had some fresh evidence this morning,” said Lestrade. “A passenger who passed Aldgate in an ordinary Metropolitan train about 11:40 on Monday night declares that he heard a heavy thud, as of a body striking the line, just before the train reached the station. There was dense fog, however, and nothing could be seen. He made no report of it at the time. Why, whatever is the matter with Mr. Holmes?”

My friend was standing with an expression of strained intensity upon his face, staring at the railway metals where they curved out of the tunnel. Aldgate is a junction, and there was a network of points. On these his eager, questioning eyes were fixed, and I saw on his keen, alert face that tightening of the lips, that quiver of the nostrils, and concentration of the heavy, tufted brows which I knew so well.

“Points,” he muttered; “the points.”

“What of it? What do you mean?”

“I suppose there are no great number of points on a system such as this?”

“No; they are very few.”

“And a curve, too. Points, and a curve. By Jove! if it were only so.”

“What is it, Mr. Holmes? Have you a clue?”

“An idea—an indication, no more. But the case certainly grows in interest. Unique, perfectly unique, and yet why not? I do not see any indications of bleeding on the line.”

“There were hardly any.”

“But I understand that there was a considerable wound.”

“The bone was crushed, but there was no great external injury.”

“And yet one would have expected some bleeding. Would it be possible for me to inspect the train which contained the passenger who heard the thud of a fall in the fog?”

“I fear not, Mr. Holmes. The train has been broken up before now, and the carriages redistributed.”

“I can assure you, Mr. Holmes,” said Lestrade, “that every carriage has been carefully examined. I saw to it myself.”

It was one of my friend’s most obvious weaknesses that he was impatient with less alert intelligences than his own.

“Very likely,” said he, turning away. “As it happens, it was not the carriages which I desired to examine. Watson, we have done all we can here. We need not trouble you any further, Mr. Lestrade. I think our investigations must now carry us to Woolwich.”

At London Bridge, Holmes wrote a telegram to his brother, which he handed to me before dispatching it. It ran thus:

See some light in the darkness, but it may possibly flicker out. Meanwhile, please send by messenger, to await return at Baker Street, a complete list of all foreign spies or international agents known to be in England, with full address.—Sherlock.

“That should be helpful, Watson,” he remarked as we took our seats in the Woolwich train. “We certainly owe Brother Mycroft a debt for having introduced us to what promises to be a really very remarkable case.”

His eager face still wore that expression of intense and high-strung energy, which showed me that some novel and suggestive circumstance had opened up a stimulating line of thought. See the foxhound with hanging ears and drooping tail as it lolls about the kennels, and compare it with the same hound as, with gleaming eyes and straining muscles, it runs upon a breast-high scent—such was the change in Holmes since the morning. He was a different man from the limp and lounging figure in the mouse-coloured dressing-gown who had prowled so restlessly only a few hours before round the fog-girt room.

“There is material here. There is scope,” said he. “I am dull indeed not to have understood its possibilities.”

“Even now they are dark to me.”

“The end is dark to me also, but I have hold of one idea which may lead us far. The man met his death elsewhere, and his body was on the roof of a carriage.”

“On the roof!”

“Remarkable, is it not? But consider the facts. Is it a coincidence that it is found at the very point where the train pitches and sways as it comes round on the points? Is not that the place where an object upon the roof might be expected to fall off? The points would affect no object inside the train. Either the body fell from the roof, or a very curious coincidence has occurred. But now consider the question of the blood. Of course, there was no bleeding on the line if the body had bled elsewhere. Each fact is suggestive in itself. Together they have a cumulative force.”

“And the ticket, too!” I cried.

“Exactly. We could not explain the absence of a ticket. This would explain it. Everything fits together.”

“But suppose it were so, we are still as far as ever from unravelling the mystery of his death. Indeed, it becomes not simpler but stranger.”

“Perhaps,” said Holmes, thoughtfully, “perhaps.” He relapsed into a silent reverie, which lasted until the slow train drew up at last in Woolwich Station. There he called a cab and drew Mycroft’s paper from his pocket.

“We have quite a little round of afternoon calls to make,” said he. “I think that Sir James Walter claims our first attention.”

The house of the famous official was a fine villa with green lawns stretching down to the Thames. As we reached it the fog was lifting, and a thin, watery sunshine was breaking through. A butler answered our ring.

“Sir James, sir!” said he with solemn face. “Sir James died this morning.”

“Good heavens!” cried Holmes in amazement. “How did he die?”

“Perhaps you would care to step in, sir, and see his brother, Colonel Valentine?”

“Yes, we had best do so.”

We were ushered into a dim-lit drawing-room, where an instant later we were joined by a very tall, handsome, light-bearded man of fifty, the younger brother of the dead scientist. His wild eyes, stained cheeks, and unkempt hair all spoke of the sudden blow which had fallen upon the household. He was hardly articulate as he spoke of it.

“It was this horrible scandal,” said he. “My brother, Sir James, was a man of very sensitive honour, and he could not survive such an affair. It broke his heart. He was always so proud of the efficiency of his department, and this was a crushing blow.”

“We had hoped that he might have given us some indications which would have helped us to clear the matter up.”

“I assure you that it was all a mystery to him as it is to you and to all of us. He had already put all his knowledge at the disposal of the police. Naturally he had no doubt that Cadogan West was guilty. But all the rest was inconceivable.”

“You cannot throw any new light upon the affair?”

“I know nothing myself save what I have read or heard. I have no desire to be discourteous, but you can understand, Mr. Holmes, that we are much disturbed at present, and I must ask you to hasten this interview to an end.”

“This is indeed an unexpected development,” said my friend when we had regained the cab. “I wonder if the death was natural, or whether the poor old fellow killed himself! If the latter, may it be taken as some sign of self-reproach for duty neglected? We must leave that question to the future. Now we shall turn to the Cadogan Wests.”

A small but well-kept house in the outskirts of the town sheltered the bereaved mother. The old lady was too dazed with grief to be of any use to us, but at her side was a white-faced young lady, who introduced herself as Miss Violet Westbury, the fiancée of the dead man, and the last to see him upon that fatal night.

“I cannot explain it, Mr. Holmes,” she said. “I have not shut an eye since the tragedy, thinking, thinking, thinking, night and day, what the true meaning of it can be. Arthur was the most single-minded, chivalrous, patriotic man upon earth. He would have cut his right hand off before he would sell a State secret confided to his keeping. It is absurd, impossible, preposterous to anyone who knew him.”

“But the facts, Miss Westbury?”

“Yes, yes; I admit I cannot explain them.”

“Was he in any want of money?”

“No; his needs were very simple and his salary ample. He had saved a few hundreds, and we were to marry at the New Year.”

“No signs of any mental excitement? Come, Miss Westbury, be absolutely frank with us.”

The quick eye of my companion had noted some change in her manner. She coloured and hesitated.

“Yes,” she said at last, “I had a feeling that there was something on his mind.”

“For long?”

“Only for the last week or so. He was thoughtful and worried. Once I pressed him about it. He admitted that there was something, and that it was concerned with his official life. ‘It is too serious for me to speak about, even to you,’ said he. I could get nothing more.”

Holmes looked grave.

“Go on, Miss Westbury. Even if it seems to tell against him, go on. We cannot say what it may lead to.”

“Indeed, I have nothing more to tell. Once or twice it seemed to me that he was on the point of telling me something. He spoke one evening of the importance of the secret, and I have some recollection that he said that no doubt foreign spies would pay a great deal to have it.”

My friend’s face grew graver still.

“Anything else?”

“He said that we were slack about such matters—that it would be easy for a traitor to get the plans.”

“Was it only recently that he made such remarks?”

“Yes, quite recently.”

“Now tell us of that last evening.”

“We were to go to the theatre. The fog was so thick that a cab was useless. We walked, and our way took us close to the office. Suddenly he darted away into the fog.”

“Without a word?”

“He gave an exclamation; that was all. I waited but he never returned. Then I walked home. Next morning, after the office opened, they came to inquire. About twelve o’clock we heard the terrible news. Oh, Mr. Holmes, if you could only, only save his honour! It was so much to him.”

Holmes shook his head sadly.

“Come, Watson,” said he, “our ways lie elsewhere. Our next station must be the office from which the papers were taken.

“It was black enough before against this young man, but our inquiries make it blacker,” he remarked as the cab lumbered off. “His coming marriage gives a motive for the crime. He naturally wanted money. The idea was in his head, since he spoke about it. He nearly made the girl an accomplice in the treason by telling her his plans. It is all very bad.”

“But surely, Holmes, character goes for something? Then, again, why should he leave the girl in the street and dart away to commit a felony?”

“Exactly! There are certainly objections. But it is a formidable case which they have to meet.”

Mr. Sidney Johnson, the senior clerk, met us at the office and received us with that respect which my companion’s card always commanded. He was a thin, gruff, bespectacled man of middle age, his cheeks haggard, and his hands twitching from the nervous strain to which he had been subjected.

“It is bad, Mr. Holmes, very bad! Have you heard of the death of the chief?”

“We have just come from his house.”

“The place is disorganised. The chief dead, Cadogan West dead, our papers stolen. And yet, when we closed our door on Monday evening, we were as efficient an office as any in the government service. Good God, it’s dreadful to think of! That West, of all men, should have done such a thing!”

“You are sure of his guilt, then?”

“I can see no other way out of it. And yet I would have trusted him as I trust myself.”

“At what hour was the office closed on Monday?”

“At five.”

“Did you close it?”

“I am always the last man out.”

“Where were the plans?”

“In that safe. I put them there myself.”

“Is there no watchman to the building?”

“There is, but he has other departments to look after as well. He is an old soldier and a most trustworthy man. He saw nothing that evening. Of course the fog was very thick.”

“Suppose that Cadogan West wished to make his way into the building after hours; he would need three keys, would he not, before he could reach the papers?”

“Yes, he would. The key of the outer door, the key of the office, and the key of the safe.”

“Only Sir James Walter and you had those keys?”

“I had no keys of the doors—only of the safe.”

“Was Sir James a man who was orderly in his habits?”

“Yes, I think he was. I know that so far as those three keys are concerned he kept them on the same ring. I have often seen them there.”

“And that ring went with him to London?”

“He said so.”

“And your key never left your possession?”

“Never.”

“Then West, if he is the culprit, must have had a duplicate. And yet none was found upon his body. One other point: if a clerk in this office desired to sell the plans, would it not be simpler to copy the plans for himself than to take the originals, as was actually done?”

“It would take considerable technical knowledge to copy the plans in an effective way.”

“But I suppose either Sir James, or you, or West has that technical knowledge?”

“No doubt we had, but I beg you won’t try to drag me into the matter, Mr. Holmes. What is the use of our speculating in this way when the original plans were actually found on West?”

“Well, it is certainly singular that he should run the risk of taking originals if he could safely have taken copies, which would have equally served his turn.”

“Singular, no doubt—and yet he did so.”

“Every inquiry in this case reveals something inexplicable. Now there are three papers still missing. They are, as I understand, the vital ones.”

“Yes, that is so.”

“Do you mean to say that anyone holding these three papers, and without the seven others, could construct a Bruce-Partington submarine?”

“I reported to that effect to the Admiralty. But to-day I have been over the drawings again, and I am not so sure of it. The double valves with the automatic self-adjusting slots are drawn in one of the papers which have been returned. Until the foreigners had invented that for themselves they could not make the boat. Of course they might soon get over the difficulty.”

“But the three missing drawings are the most important?”

“Undoubtedly.”

“I think, with your permission, I will now take a stroll round the premises. I do not recall any other question which I desired to ask.”

He examined the lock of the safe, the door of the room, and finally the iron shutters of the window. It was only when we were on the lawn outside that his interest was strongly excited. There was a laurel bush outside the window, and several of the branches bore signs of having been twisted or snapped. He examined them carefully with his lens, and then some dim and vague marks upon the earth beneath. Finally he asked the chief clerk to close the iron shutters, and he pointed out to me that they hardly met in the centre, and that it would be possible for anyone outside to see what was going on within the room.

“The indications are ruined by three days’ delay. They may mean something or nothing. Well, Watson, I do not think that Woolwich can help us further. It is a small crop which we have gathered. Let us see if we can do better in London.”

Yet we added one more sheaf to our harvest before we left Woolwich Station. The clerk in the ticket office was able to say with confidence that he saw Cadogan West—whom he knew well by sight—upon the Monday night, and that he went to London by the 8:15 to London Bridge. He was alone and took a single third-class ticket. The clerk was struck at the time by his excited and nervous manner. So shaky was he that he could hardly pick up his change, and the clerk had helped him with it. A reference to the timetable showed that the 8:15 was the first train which it was possible for West to take after he had left the lady about 7:30.

“Let us reconstruct, Watson,” said Holmes after half an hour of silence. “I am not aware that in all our joint researches we have ever had a case which was more difficult to get at. Every fresh advance which we make only reveals a fresh ridge beyond. And yet we have surely made some appreciable progress.

“The effect of our inquiries at Woolwich has in the main been against young Cadogan West; but the indications at the window would lend themselves to a more favourable hypothesis. Let us suppose, for example, that he had been approached by some foreign agent. It might have been done under such pledges as would have prevented him from speaking of it, and yet would have affected his thoughts in the direction indicated by his remarks to his fiancée. Very good. We will now suppose that as he went to the theatre with the young lady he suddenly, in the fog, caught a glimpse of this same agent going in the direction of the office. He was an impetuous man, quick in his decisions. Everything gave way to his duty. He followed the man, reached the window, saw the abstraction of the documents, and pursued the thief. In this way we get over the objection that no one would take originals when he could make copies. This outsider had to take originals. So far it holds together.”

“What is the next step?”

“Then we come into difficulties. One would imagine that under such circumstances the first act of young Cadogan West would be to seize the villain and raise the alarm. Why did he not do so? Could it have been an official superior who took the papers? That would explain West’s conduct. Or could the chief have given West the slip in the fog, and West started at once to London to head him off from his own rooms, presuming that he knew where the rooms were? The call must have been very pressing, since he left his girl standing in the fog and made no effort to communicate with her. Our scent runs cold here, and there is a vast gap between either hypothesis and the laying of West’s body, with seven papers in his pocket, on the roof of a Metropolitan train. My instinct now is to work from the other end. If Mycroft has given us the list of addresses we may be able to pick our man and follow two tracks instead of one.”

Surely enough, a note awaited us at Baker Street. A government messenger had brought it post-haste. Holmes glanced at it and threw it over to me.

There are numerous small fry, but few who would handle so big an affair. The only men worth considering are Adolph Mayer, of 13, Great George Street, Westminster; Louis La Rothière, of Campden Mansions, Notting Hill; and Hugo Oberstein, 13, Caulfield Gardens, Kensington. The latter was known to be in town on Monday and is now reported as having left. Glad to hear you have seen some light. The Cabinet awaits your final report with the utmost anxiety. Urgent representations have arrived from the very highest quarter. The whole force of the State is at your back if you should need it.—Mycroft.

“I’m afraid,” said Holmes, smiling, “that all the Queen’s horses and all the Queen’s men cannot avail in this matter.” He had spread out his big map of London and leaned eagerly over it. “Well, well,” said he presently with an exclamation of satisfaction, “things are turning a little in our direction at last. Why, Watson, I do honestly believe that we are going to pull it off, after all.” He slapped me on the shoulder with a sudden burst of hilarity. “I am going out now. It is only a reconnaissance. I will do nothing serious without my trusted comrade and biographer at my elbow. Do you stay here, and the odds are that you will see me again in an hour or two. If time hangs heavy get foolscap and a pen, and begin your narrative of how we saved the State.”

I felt some reflection of his elation in my own mind, for I knew well that he would not depart so far from his usual austerity of demeanour unless there was good cause for exultation. All the long November evening I waited, filled with impatience for his return. At last, shortly after nine o’clock, there arrived a messenger with a note:

Am dining at Goldini’s Restaurant, Gloucester Road, Kensington. Please come at once and join me there. Bring with you a jemmy, a dark lantern, a chisel, and a revolver.—S.H.

It was a nice equipment for a respectable citizen to carry through the dim, fog-draped streets. I stowed them all discreetly away in my overcoat and drove straight to the address given. There sat my friend at a little round table near the door of the garish Italian restaurant.

“Have you had something to eat? Then join me in a coffee and curaçao. Try one of the proprietor’s cigars. They are less poisonous than one would expect. Have you the tools?”

“They are here, in my overcoat.”

“Excellent. Let me give you a short sketch of what I have done, with some indication of what we are about to do. Now it must be evident to you, Watson, that this young man’s body was placed on the roof of the train. That was clear from the instant that I determined the fact that it was from the roof, and not from a carriage, that he had fallen.”

“Could it not have been dropped from a bridge?”

“I should say it was impossible. If you examine the roofs you will find that they are slightly rounded, and there is no railing round them. Therefore, we can say for certain that young Cadogan West was placed on it.”

“How could he be placed there?”

“That was the question which we had to answer. There is only one possible way. You are aware that the Underground runs clear of tunnels at some points in the West End. I had a vague memory that as I have travelled by it I have occasionally seen windows just above my head. Now, suppose that a train halted under such a window, would there be any difficulty in laying a body upon the roof?”

“It seems most improbable.”

“We must fall back upon the old axiom that when all other contingencies fail, whatever remains, however improbable, must be the truth. Here all other contingencies have failed. When I found that the leading international agent, who had just left London, lived in a row of houses which abutted upon the Underground, I was so pleased that you were a little astonished at my sudden frivolity.”

“Oh, that was it, was it?”

“Yes, that was it. Mr. Hugo Oberstein, of 13, Caulfield Gardens, had become my objective. I began my operations at Gloucester Road Station, where a very helpful official walked with me along the track and allowed me to satisfy myself not only that the back-stair windows of Caulfield Gardens open on the line but the even more essential fact that, owing to the intersection of one of the larger railways, the Underground trains are frequently held motionless for some minutes at that very spot.”

“Splendid, Holmes! You have got it!”

“So far—so far, Watson. We advance, but the goal is afar. Well, having seen the back of Caulfield Gardens, I visited the front and satisfied myself that the bird was indeed flown. It is a considerable house, unfurnished, so far as I could judge, in the upper rooms. Oberstein lived there with a single valet, who was probably a confederate entirely in his confidence. We must bear in mind that Oberstein has gone to the Continent to dispose of his booty, but not with any idea of flight; for he had no reason to fear a warrant, and the idea of an amateur domiciliary visit would certainly never occur to him. Yet that is precisely what we are about to make.”

“Could we not get a warrant and legalise it?”

“Hardly on the evidence.”

“What can we hope to do?”

“We cannot tell what correspondence may be there.”

“I don’t like it, Holmes.”

“My dear fellow, you shall keep watch in the street. I’ll do the criminal part. It’s not a time to stick at trifles. Think of Mycroft’s note, of the Admiralty, the Cabinet, the exalted person who waits for news. We are bound to go.”

My answer was to rise from the table.

“You are right, Holmes. We are bound to go.”

He sprang up and shook me by the hand.

“I knew you would not shrink at the last,” said he, and for a moment I saw something in his eyes which was nearer to tenderness than I had ever seen. The next instant he was his masterful, practical self once more.

“It is nearly half a mile, but there is no hurry. Let us walk,” said he. “Don’t drop the instruments, I beg. Your arrest as a suspicious character would be a most unfortunate complication.”

Caulfield Gardens was one of those lines of flat-faced pillared, and porticoed houses which are so prominent a product of the middle Victorian epoch in the West End of London. Next door there appeared to be a children’s party, for the merry buzz of young voices and the clatter of a piano resounded through the night. The fog still hung about and screened us with its friendly shade. Holmes had lit his lantern and flashed it upon the massive door.

“This is a serious proposition,” said he. “It is certainly bolted as well as locked. We would do better in the area. There is an excellent archway down yonder in case a too zealous policeman should intrude. Give me a hand, Watson, and I’ll do the same for you.”

A minute later we were both in the area. Hardly had we reached the dark shadows before the step of the policeman was heard in the fog above. As its soft rhythm died away, Holmes set to work upon the lower door. I saw him stoop and strain until with a sharp crash it flew open. We sprang through into the dark passage, closing the area door behind us. Holmes led the way up the curving, uncarpeted stair. His little fan of yellow light shone upon a low window.

“Here we are, Watson—this must be the one.” He threw it open, and as he did so there was a low, harsh murmur, growing steadily into a loud roar as a train dashed past us in the darkness. Holmes swept his light along the window-sill. It was thickly coated with soot from the passing engines, but the black surface was blurred and rubbed in places.

“You can see where they rested the body. Halloa, Watson! what is this? There can be no doubt that it is a blood mark.” He was pointing to faint discolorations along the woodwork of the window. “Here it is on the stone of the stair also. The demonstration is complete. Let us stay here until a train stops.”

We had not long to wait. The very next train roared from the tunnel as before, but slowed in the open, and then, with a creaking of brakes, pulled up immediately beneath us. It was not four feet from the window-ledge to the roof of the carriages. Holmes softly closed the window.

“So far we are justified,” said he. “What do you think of it, Watson?”

“A masterpiece. You have never risen to a greater height.”

“I cannot agree with you there. From the moment that I conceived the idea of the body being upon the roof, which surely was not a very abstruse one, all the rest was inevitable. If it were not for the grave interests involved the affair up to this point would be insignificant. Our difficulties are still before us. But perhaps we may find something here which may help us.”

We had ascended the kitchen stair and entered the suite of rooms upon the first floor. One was a dining-room, severely furnished and containing nothing of interest. A second was a bedroom, which also drew blank. The remaining room appeared more promising, and my companion settled down to a systematic examination. It was littered with books and papers, and was evidently used as a study. Swiftly and methodically Holmes turned over the contents of drawer after drawer and cupboard after cupboard, but no gleam of success came to brighten his austere face. At the end of an hour he was no further than when he started.

“The cunning dog has covered his tracks,” said he. “He has left nothing to incriminate him. His dangerous correspondence has been destroyed or removed. This is our last chance.”

It was a small tin cash-box which stood upon the writing-desk. Holmes pried it open with his chisel. Several rolls of paper were within, covered with figures and calculations, without any note to show to what they referred. The recurring words, “water pressure” and “pressure to the square inch” suggested some possible relation to a submarine. Holmes tossed them all impatiently aside. There only remained an envelope with some small newspaper slips inside it. He shook them out on the table, and at once I saw by his eager face that his hopes had been raised.

“What’s this, Watson? Eh? What’s this? Record of a series of messages in the advertisements of a paper. Daily Telegraph agony column by the print and paper. Right-hand top corner of a page. No dates—but messages arrange themselves. This must be the first:

“Hoped to hear sooner. Terms agreed to. Write fully to address given on card.—Pierrot.

“Next comes:

“Too complex for description. Must have full report. Stuff awaits you when goods delivered.—Pierrot.

“Then comes:

“Matter presses. Must withdraw offer unless contract completed. Make appointment by letter. Will confirm by advertisement.—Pierrot.

“Finally:

“Monday night after nine. Two taps. Only ourselves. Do not be so suspicious. Payment in hard cash when goods delivered.—Pierrot.

“A fairly complete record, Watson! If we could only get at the man at the other end!” He sat lost in thought, tapping his fingers on the table. Finally he sprang to his feet.

“Well, perhaps it won’t be so difficult, after all. There is nothing more to be done here, Watson. I think we might drive round to the offices of the Daily Telegraph, and so bring a good day’s work to a conclusion.”

Mycroft Holmes and Lestrade had come round by appointment after breakfast next day and Sherlock Holmes had recounted to them our proceedings of the day before. The professional shook his head over our confessed burglary.

“We can’t do these things in the force, Mr. Holmes,” said he. “No wonder you get results that are beyond us. But some of these days you’ll go too far, and you’ll find yourself and your friend in trouble.”

“For England, home and beauty—eh, Watson? Martyrs on the altar of our country. But what do you think of it, Mycroft?”

“Excellent, Sherlock! Admirable! But what use will you make of it?”

Holmes picked up the Daily Telegraph which lay upon the table.

“Have you seen Pierrot’s advertisement to-day?”

“What? Another one?”

“Yes, here it is:

“To-night. Same hour. Same place. Two taps. Most vitally important. Your own safety at stake.—Pierrot.

“By George!” cried Lestrade. “If he answers that we’ve got him!”

“That was my idea when I put it in. I think if you could both make it convenient to come with us about eight o’clock to Caulfield Gardens we might possibly get a little nearer to a solution.”

One of the most remarkable characteristics of Sherlock Holmes was his power of throwing his brain out of action and switching all his thoughts on to lighter things whenever he had convinced himself that he could no longer work to advantage. I remember that during the whole of that memorable day he lost himself in a monograph which he had undertaken upon the Polyphonic Motets of Lassus. For my own part I had none of this power of detachment, and the day, in consequence, appeared to be interminable. The great national importance of the issue, the suspense in high quarters, the direct nature of the experiment which we were trying—all combined to work upon my nerve. It was a relief to me when at last, after a light dinner, we set out upon our expedition. Lestrade and Mycroft met us by appointment at the outside of Gloucester Road Station. The area door of Oberstein’s house had been left open the night before, and it was necessary for me, as Mycroft Holmes absolutely and indignantly declined to climb the railings, to pass in and open the hall door. By nine o’clock we were all seated in the study, waiting patiently for our man.

An hour passed and yet another. When eleven struck, the measured beat of the great church clock seemed to sound the dirge of our hopes. Lestrade and Mycroft were fidgeting in their seats and looking twice a minute at their watches. Holmes sat silent and composed, his eyelids half shut, but every sense on the alert. He raised his head with a sudden jerk.

“He is coming,” said he.

There had been a furtive step past the door. Now it returned. We heard a shuffling sound outside, and then two sharp taps with the knocker. Holmes rose, motioning us to remain seated. The gas in the hall was a mere point of light. He opened the outer door, and then as a dark figure slipped past him he closed and fastened it. “This way!” we heard him say, and a moment later our man stood before us. Holmes had followed him closely, and as the man turned with a cry of surprise and alarm he caught him by the collar and threw him back into the room. Before our prisoner had recovered his balance the door was shut and Holmes standing with his back against it. The man glared round him, staggered, and fell senseless upon the floor. With the shock, his broad-brimmed hat flew from his head, his cravat slipped down from his lips, and there were the long light beard and the soft, handsome delicate features of Colonel Valentine Walter.

Holmes gave a whistle of surprise.

“You can write me down an ass this time, Watson,” said he. “This was not the bird that I was looking for.”

“Who is he?” asked Mycroft eagerly.

“The younger brother of the late Sir James Walter, the head of the Submarine Department. Yes, yes; I see the fall of the cards. He is coming to. I think that you had best leave his examination to me.”

We had carried the prostrate body to the sofa. Now our prisoner sat up, looked round him with a horror-stricken face, and passed his hand over his forehead, like one who cannot believe his own senses.

“What is this?” he asked. “I came here to visit Mr. Oberstein.”

“Everything is known, Colonel Walter,” said Holmes. “How an English gentleman could behave in such a manner is beyond my comprehension. But your whole correspondence and relations with Oberstein are within our knowledge. So also are the circumstances connected with the death of young Cadogan West. Let me advise you to gain at least the small credit for repentance and confession, since there are still some details which we can only learn from your lips.”

The man groaned and sank his face in his hands. We waited, but he was silent.

“I can assure you,” said Holmes, “that every essential is already known. We know that you were pressed for money; that you took an impress of the keys which your brother held; and that you entered into a correspondence with Oberstein, who answered your letters through the advertisement columns of the Daily Telegraph. We are aware that you went down to the office in the fog on Monday night, but that you were seen and followed by young Cadogan West, who had probably some previous reason to suspect you. He saw your theft, but could not give the alarm, as it was just possible that you were taking the papers to your brother in London. Leaving all his private concerns, like the good citizen that he was, he followed you closely in the fog and kept at your heels until you reached this very house. There he intervened, and then it was, Colonel Walter, that to treason you added the more terrible crime of murder.”

“I did not! I did not! Before God I swear that I did not!” cried our wretched prisoner.

“Tell us, then, how Cadogan West met his end before you laid him upon the roof of a railway carriage.”

“I will. I swear to you that I will. I did the rest. I confess it. It was just as you say. A Stock Exchange debt had to be paid. I needed the money badly. Oberstein offered me five thousand. It was to save myself from ruin. But as to murder, I am as innocent as you.”

“What happened, then?”

“He had his suspicions before, and he followed me as you describe. I never knew it until I was at the very door. It was thick fog, and one could not see three yards. I had given two taps and Oberstein had come to the door. The young man rushed up and demanded to know what we were about to do with the papers. Oberstein had a short life-preserver. He always carried it with him. As West forced his way after us into the house Oberstein struck him on the head. The blow was a fatal one. He was dead within five minutes. There he lay in the hall, and we were at our wits’ end what to do. Then Oberstein had this idea about the trains which halted under his back window. But first he examined the papers which I had brought. He said that three of them were essential, and that he must keep them. ‘You cannot keep them,’ said I. ‘There will be a dreadful row at Woolwich if they are not returned.’ ‘I must keep them,’ said he, ‘for they are so technical that it is impossible in the time to make copies.’ ‘Then they must all go back together to-night,’ said I. He thought for a little, and then he cried out that he had it. ‘Three I will keep,’ said he. ‘The others we will stuff into the pocket of this young man. When he is found the whole business will assuredly be put to his account.’ I could see no other way out of it, so we did as he suggested. We waited half an hour at the window before a train stopped. It was so thick that nothing could be seen, and we had no difficulty in lowering West’s body on to the train. That was the end of the matter so far as I was concerned.”

“And your brother?”

“He said nothing, but he had caught me once with his keys, and I think that he suspected. I read in his eyes that he suspected. As you know, he never held up his head again.”

There was silence in the room. It was broken by Mycroft Holmes.

“Can you not make reparation? It would ease your conscience, and possibly your punishment.”

“What reparation can I make?”

“Where is Oberstein with the papers?”

“I do not know.”

“Did he give you no address?”

“He said that letters to the Hôtel du Louvre, Paris, would eventually reach him.”

“Then reparation is still within your power,” said Sherlock Holmes.

“I will do anything I can. I owe this fellow no particular good-will. He has been my ruin and my downfall.”

“Here are paper and pen. Sit at this desk and write to my dictation. Direct the envelope to the address given. That is right. Now the letter:

“Dear Sir:
“With regard to our transaction, you will no doubt have observed by now that one essential detail is missing. I have a tracing which will make it complete. This has involved me in extra trouble, however, and I must ask you for a further advance of five hundred pounds. I will not trust it to the post, nor will I take anything but gold or notes. I would come to you abroad, but it would excite remark if I left the country at present. Therefore I shall expect to meet you in the smoking-room of the Charing Cross Hotel at noon on Saturday. Remember that only English notes, or gold, will be taken.

“That will do very well. I shall be very much surprised if it does not fetch our man.”

And it did! It is a matter of history—that secret history of a nation which is often so much more intimate and interesting than its public chronicles—that Oberstein, eager to complete the coup of his lifetime, came to the lure and was safely engulfed for fifteen years in a British prison. In his trunk were found the invaluable Bruce-Partington plans, which he had put up for auction in all the naval centres of Europe.

Colonel Walter died in prison towards the end of the second year of his sentence. As to Holmes, he returned refreshed to his monograph upon the Polyphonic Motets of Lassus, which has since been printed for private circulation, and is said by experts to be the last word upon the subject. Some weeks afterwards I learned incidentally that my friend spent a day at Windsor, whence he returned with a remarkably fine emerald tie-pin. When I asked him if he had bought it, he answered that it was a present from a certain gracious lady in whose interests he had once been fortunate enough to carry out a small commission. He said no more; but I fancy that I could guess at that lady’s august name, and I have little doubt that the emerald pin will forever recall to my friend’s memory the adventure of the Bruce-Partington plans.

The Adventure of the Devil’s Foot

In recording from time to time some of the curious experiences and interesting recollections which I associate with my long and intimate friendship with Mr. Sherlock Holmes, I have continually been faced by difficulties caused by his own aversion to publicity. To his sombre and cynical spirit all popular applause was always abhorrent, and nothing amused him more at the end of a successful case than to hand over the actual exposure to some orthodox official, and to listen with a mocking smile to the general chorus of misplaced congratulation. It was indeed this attitude upon the part of my friend and certainly not any lack of interesting material which has caused me of late years to lay very few of my records before the public. My participation in some of his adventures was always a privilege which entailed discretion and reticence upon me.

It was, then, with considerable surprise that I received a telegram from Holmes last Tuesday—he has never been known to write where a telegram would serve—in the following terms: “Why not tell them of the Cornish horror—strangest case I have handled.” I have no idea what backward sweep of memory had brought the matter fresh to his mind, or what freak had caused him to desire that I should recount it; but I hasten, before another cancelling telegram may arrive, to hunt out the notes which give me the exact details of the case and to lay the narrative before my readers.

It was, then, in the spring of the year 1897 that Holmes’s iron constitution showed some symptoms of giving way in the face of constant hard work of a most exacting kind, aggravated, perhaps, by occasional indiscretions of his own. In March of that year Dr. Moore Agar, of Harley Street, whose dramatic introduction to Holmes I may some day recount, gave positive injunctions that the famous private agent lay aside all his cases and surrender himself to complete rest if he wished to avert an absolute breakdown. The state of his health was not a matter in which he himself took the faintest interest, for his mental detachment was absolute, but he was induced at last, on the threat of being permanently disqualified from work, to give himself a complete change of scene and air. Thus it was that in the early spring of that year we found ourselves together in a small cottage near Poldhu Bay, at the further extremity of the Cornish peninsula.

It was a singular spot, and one peculiarly well suited to the grim humour of my patient. From the windows of our little whitewashed house, which stood high upon a grassy headland, we looked down upon the whole sinister semi-circle of Mounts Bay, that old death trap of sailing vessels, with its fringe of black cliffs and surge-swept reefs on which innumerable seamen have met their end. With a northerly breeze it lies placid and sheltered, inviting the storm-tossed craft to tack into it for rest and protection.

Then come the sudden swirl round of the wind, the blistering gale from the south-west, the dragging anchor, the lee shore, and the last battle in the creaming breakers. The wise mariner stands far out from that evil place.

On the land side our surroundings were as sombre as on the sea. It was a country of rolling moors, lonely and dun-coloured, with an occasional church tower to mark the site of some old-world village. In every direction upon these moors there were traces of some vanished race which had passed utterly away, and left as its sole record strange monuments of stone, irregular mounds which contained the burned ashes of the dead, and curious earthworks which hinted at prehistoric strife. The glamour and mystery of the place, with its sinister atmosphere of forgotten nations, appealed to the imagination of my friend, and he spent much of his time in long walks and solitary meditations upon the moor. The ancient Cornish language had also arrested his attention, and he had, I remember, conceived the idea that it was akin to the Chaldean, and had been largely derived from the Phœnician traders in tin. He had received a consignment of books upon philology and was settling down to develop this thesis when suddenly, to my sorrow and to his unfeigned delight, we found ourselves, even in that land of dreams, plunged into a problem at our very doors which was more intense, more engrossing, and infinitely more mysterious than any of those which had driven us from London. Our simple life and peaceful, healthy routine were violently interrupted, and we were precipitated into the midst of a series of events which caused the utmost excitement not only in Cornwall but throughout the whole west of England. Many of my readers may retain some recollection of what was called at the time “The Cornish Horror,” though a most imperfect account of the matter reached the London press. Now, after thirteen years, I will give the true details of this inconceivable affair to the public.

I have said that scattered towers marked the villages which dotted this part of Cornwall. The nearest of these was the hamlet of Tredannick Wollas, where the cottages of a couple of hundred inhabitants clustered round an ancient, moss-grown church. The vicar of the parish, Mr. Roundhay, was something of an archæologist, and as such Holmes had made his acquaintance. He was a middle-aged man, portly and affable, with a considerable fund of local lore. At his invitation we had taken tea at the vicarage and had come to know, also, Mr. Mortimer Tregennis, an independent gentleman, who increased the clergyman’s scanty resources by taking rooms in his large, straggling house. The vicar, being a bachelor, was glad to come to such an arrangement, though he had little in common with his lodger, who was a thin, dark, spectacled man, with a stoop which gave the impression of actual, physical deformity. I remember that during our short visit we found the vicar garrulous, but his lodger strangely reticent, a sad-faced, introspective man, sitting with averted eyes, brooding apparently upon his own affairs.

These were the two men who entered abruptly into our little sitting-room on Tuesday, March the 16th, shortly after our breakfast hour, as we were smoking together, preparatory to our daily excursion upon the moors.

“Mr. Holmes,” said the vicar in an agitated voice, “the most extraordinary and tragic affair has occurred during the night. It is the most unheard-of business. We can only regard it as a special Providence that you should chance to be here at the time, for in all England you are the one man we need.”

I glared at the intrusive vicar with no very friendly eyes; but Holmes took his pipe from his lips and sat up in his chair like an old hound who hears the view-halloa. He waved his hand to the sofa, and our palpitating visitor with his agitated companion sat side by side upon it. Mr. Mortimer Tregennis was more self-contained than the clergyman, but the twitching of his thin hands and the brightness of his dark eyes showed that they shared a common emotion.

“Shall I speak or you?” he asked of the vicar.

“Well, as you seem to have made the discovery, whatever it may be, and the vicar to have had it second-hand, perhaps you had better do the speaking,” said Holmes.

I glanced at the hastily clad clergyman, with the formally dressed lodger seated beside him, and was amused at the surprise which Holmes’s simple deduction had brought to their faces.

“Perhaps I had best say a few words first,” said the vicar, “and then you can judge if you will listen to the details from Mr. Tregennis, or whether we should not hasten at once to the scene of this mysterious affair. I may explain, then, that our friend here spent last evening in the company of his two brothers, Owen and George, and of his sister Brenda, at their house of Tredannick Wartha, which is near the old stone cross upon the moor. He left them shortly after ten o’clock, playing cards round the dining-room table, in excellent health and spirits. This morning, being an early riser, he walked in that direction before breakfast and was overtaken by the carriage of Dr. Richards, who explained that he had just been sent for on a most urgent call to Tredannick Wartha. Mr. Mortimer Tregennis naturally went with him. When he arrived at Tredannick Wartha he found an extraordinary state of things. His two brothers and his sister were seated round the table exactly as he had left them, the cards still spread in front of them and the candles burned down to their sockets. The sister lay back stone-dead in her chair, while the two brothers sat on each side of her laughing, shouting, and singing, the senses stricken clean out of them. All three of them, the dead woman and the two demented men, retained upon their faces an expression of the utmost horror—a convulsion of terror which was dreadful to look upon. There was no sign of the presence of anyone in the house, except Mrs. Porter, the old cook and housekeeper, who declared that she had slept deeply and heard no sound during the night. Nothing had been stolen or disarranged, and there is absolutely no explanation of what the horror can be which has frightened a woman to death and two strong men out of their senses. There is the situation, Mr. Holmes, in a nutshell, and if you can help us to clear it up you will have done a great work.”

I had hoped that in some way I could coax my companion back into the quiet which had been the object of our journey; but one glance at his intense face and contracted eyebrows told me how vain was now the expectation. He sat for some little time in silence, absorbed in the strange drama which had broken in upon our peace.

“I will look into this matter,” he said at last. “On the face of it, it would appear to be a case of a very exceptional nature. Have you been there yourself, Mr. Roundhay?”

“No, Mr. Holmes. Mr. Tregennis brought back the account to the vicarage, and I at once hurried over with him to consult you.”

“How far is it to the house where this singular tragedy occurred?”

“About a mile inland.”

“Then we shall walk over together. But before we start I must ask you a few questions, Mr. Mortimer Tregennis.”

The other had been silent all this time, but I had observed that his more controlled excitement was even greater than the obtrusive emotion of the clergyman. He sat with a pale, drawn face, his anxious gaze fixed upon Holmes, and his thin hands clasped convulsively together. His pale lips quivered as he listened to the dreadful experience which had befallen his family, and his dark eyes seemed to reflect something of the horror of the scene.

“Ask what you like, Mr. Holmes,” said he eagerly. “It is a bad thing to speak of, but I will answer you the truth.”

“Tell me about last night.”

“Well, Mr. Holmes, I supped there, as the vicar has said, and my elder brother George proposed a game of whist afterwards. We sat down about nine o’clock. It was a quarter-past ten when I moved to go. I left them all round the table, as merry as could be.”

“Who let you out?”

“Mrs. Porter had gone to bed, so I let myself out. I shut the hall door behind me. The window of the room in which they sat was closed, but the blind was not drawn down. There was no change in door or window this morning, or any reason to think that any stranger had been to the house. Yet there they sat, driven clean mad with terror, and Brenda lying dead of fright, with her head hanging over the arm of the chair. I’ll never get the sight of that room out of my mind so long as I live.”

“The facts, as you state them, are certainly most remarkable,” said Holmes. “I take it that you have no theory yourself which can in any way account for them?”

“It’s devilish, Mr. Holmes, devilish!” cried Mortimer Tregennis. “It is not of this world. Something has come into that room which has dashed the light of reason from their minds. What human contrivance could do that?”

“I fear,” said Holmes, “that if the matter is beyond humanity it is certainly beyond me. Yet we must exhaust all natural explanations before we fall back upon such a theory as this. As to yourself, Mr. Tregennis, I take it you were divided in some way from your family, since they lived together and you had rooms apart?”

“That is so, Mr. Holmes, though the matter is past and done with. We were a family of tin-miners at Redruth, but we sold our venture to a company, and so retired with enough to keep us. I won’t deny that there was some feeling about the division of the money and it stood between us for a time, but it was all forgiven and forgotten, and we were the best of friends together.”

“Looking back at the evening which you spent together, does anything stand out in your memory as throwing any possible light upon the tragedy? Think carefully, Mr. Tregennis, for any clue which can help me.”

“There is nothing at all, sir.”

“Your people were in their usual spirits?”

“Never better.”

“Were they nervous people? Did they ever show any apprehension of coming danger?”

“Nothing of the kind.”

“You have nothing to add then, which could assist me?”

Mortimer Tregennis considered earnestly for a moment.

“There is one thing that occurs to me,” said he at last. “As we sat at the table my back was to the window, and my brother George, he being my partner at cards, was facing it. I saw him once look hard over my shoulder, so I turned round and looked also. The blind was up and the window shut, but I could just make out the bushes on the lawn, and it seemed to me for a moment that I saw something moving among them. I couldn’t even say if it was man or animal, but I just thought there was something there. When I asked him what he was looking at, he told me that he had the same feeling. That is all that I can say.”

“Did you not investigate?”

“No; the matter passed as unimportant.”

“You left them, then, without any premonition of evil?”

“None at all.”

“I am not clear how you came to hear the news so early this morning.”

“I am an early riser and generally take a walk before breakfast. This morning I had hardly started when the doctor in his carriage overtook me. He told me that old Mrs. Porter had sent a boy down with an urgent message. I sprang in beside him and we drove on. When we got there we looked into that dreadful room. The candles and the fire must have burned out hours before, and they had been sitting there in the dark until dawn had broken. The doctor said Brenda must have been dead at least six hours. There were no signs of violence. She just lay across the arm of the chair with that look on her face. George and Owen were singing snatches of songs and gibbering like two great apes. Oh, it was awful to see! I couldn’t stand it, and the doctor was as white as a sheet. Indeed, he fell into a chair in a sort of faint, and we nearly had him on our hands as well.”

“Remarkable—most remarkable!” said Holmes, rising and taking his hat. “I think, perhaps, we had better go down to Tredannick Wartha without further delay. I confess that I have seldom known a case which at first sight presented a more singular problem.”

Our proceedings of that first morning did little to advance the investigation. It was marked, however, at the outset by an incident which left the most sinister impression upon my mind. The approach to the spot at which the tragedy occurred is down a narrow, winding, country lane. While we made our way along it we heard the rattle of a carriage coming towards us and stood aside to let it pass. As it drove by us I caught a glimpse through the closed window of a horribly contorted, grinning face glaring out at us. Those staring eyes and gnashing teeth flashed past us like a dreadful vision.

“My brothers!” cried Mortimer Tregennis, white to his lips. “They are taking them to Helston.”

We looked with horror after the black carriage, lumbering upon its way. Then we turned our steps towards this ill-omened house in which they had met their strange fate.

It was a large and bright dwelling, rather a villa than a cottage, with a considerable garden which was already, in that Cornish air, well filled with spring flowers. Towards this garden the window of the sitting-room fronted, and from it, according to Mortimer Tregennis, must have come that thing of evil which had by sheer horror in a single instant blasted their minds. Holmes walked slowly and thoughtfully among the flower-plots and along the path before we entered the porch. So absorbed was he in his thoughts, I remember, that he stumbled over the watering-pot, upset its contents, and deluged both our feet and the garden path. Inside the house we were met by the elderly Cornish housekeeper, Mrs. Porter, who, with the aid of a young girl, looked after the wants of the family. She readily answered all Holmes’s questions. She had heard nothing in the night. Her employers had all been in excellent spirits lately, and she had never known them more cheerful and prosperous. She had fainted with horror upon entering the room in the morning and seeing that dreadful company round the table. She had, when she recovered, thrown open the window to let the morning air in, and had run down to the lane, whence she sent a farm-lad for the doctor. The lady was on her bed upstairs if we cared to see her. It took four strong men to get the brothers into the asylum carriage. She would not herself stay in the house another day and was starting that very afternoon to rejoin her family at St. Ives.

We ascended the stairs and viewed the body. Miss Brenda Tregennis had been a very beautiful girl, though now verging upon middle age. Her dark, clear-cut face was handsome, even in death, but there still lingered upon it something of that convulsion of horror which had been her last human emotion. From her bedroom we descended to the sitting-room, where this strange tragedy had actually occurred. The charred ashes of the overnight fire lay in the grate. On the table were the four guttered and burned-out candles, with the cards scattered over its surface. The chairs had been moved back against the walls, but all else was as it had been the night before. Holmes paced with light, swift steps about the room; he sat in the various chairs, drawing them up and reconstructing their positions. He tested how much of the garden was visible; he examined the floor, the ceiling, and the fireplace; but never once did I see that sudden brightening of his eyes and tightening of his lips which would have told me that he saw some gleam of light in this utter darkness.

“Why a fire?” he asked once. “Had they always a fire in this small room on a spring evening?”

Mortimer Tregennis explained that the night was cold and damp. For that reason, after his arrival, the fire was lit. “What are you going to do now, Mr. Holmes?” he asked.

My friend smiled and laid his hand upon my arm. “I think, Watson, that I shall resume that course of tobacco-poisoning which you have so often and so justly condemned,” said he. “With your permission, gentlemen, we will now return to our cottage, for I am not aware that any new factor is likely to come to our notice here. I will turn the facts over in my mind, Mr. Tregennis, and should anything occur to me I will certainly communicate with you and the vicar. In the meantime I wish you both good-morning.”

It was not until long after we were back in Poldhu Cottage that Holmes broke his complete and absorbed silence. He sat coiled in his armchair, his haggard and ascetic face hardly visible amid the blue swirl of his tobacco smoke, his black brows drawn down, his forehead contracted, his eyes vacant and far away. Finally he laid down his pipe and sprang to his feet.

“It won’t do, Watson!” said he with a laugh. “Let us walk along the cliffs together and search for flint arrows. We are more likely to find them than clues to this problem. To let the brain work without sufficient material is like racing an engine. It racks itself to pieces. The sea air, sunshine, and patience, Watson—all else will come.

“Now, let us calmly define our position, Watson,” he continued as we skirted the cliffs together. “Let us get a firm grip of the very little which we do know, so that when fresh facts arise we may be ready to fit them into their places. I take it, in the first place, that neither of us is prepared to admit diabolical intrusions into the affairs of men. Let us begin by ruling that entirely out of our minds. Very good. There remain three persons who have been grievously stricken by some conscious or unconscious human agency. That is firm ground. Now, when did this occur? Evidently, assuming his narrative to be true, it was immediately after Mr. Mortimer Tregennis had left the room. That is a very important point. The presumption is that it was within a few minutes afterwards. The cards still lay upon the table. It was already past their usual hour for bed. Yet they had not changed their position or pushed back their chairs. I repeat, then, that the occurrence was immediately after his departure, and not later than eleven o’clock last night.

“Our next obvious step is to check, so far as we can, the movements of Mortimer Tregennis after he left the room. In this there is no difficulty, and they seem to be above suspicion. Knowing my methods as you do, you were, of course, conscious of the somewhat clumsy water-pot expedient by which I obtained a clearer impress of his foot than might otherwise have been possible. The wet, sandy path took it admirably. Last night was also wet, you will remember, and it was not difficult—having obtained a sample print—to pick out his track among others and to follow his movements. He appears to have walked away swiftly in the direction of the vicarage.

“If, then, Mortimer Tregennis disappeared from the scene, and yet some outside person affected the card-players, how can we reconstruct that person, and how was such an impression of horror conveyed? Mrs. Porter may be eliminated. She is evidently harmless. Is there any evidence that someone crept up to the garden window and in some manner produced so terrific an effect that he drove those who saw it out of their senses? The only suggestion in this direction comes from Mortimer Tregennis himself, who says that his brother spoke about some movement in the garden. That is certainly remarkable, as the night was rainy, cloudy, and dark. Anyone who had the design to alarm these people would be compelled to place his very face against the glass before he could be seen. There is a three-foot flower-border outside this window, but no indication of a footmark. It is difficult to imagine, then, how an outsider could have made so terrible an impression upon the company, nor have we found any possible motive for so strange and elaborate an attempt. You perceive our difficulties, Watson?”

“They are only too clear,” I answered with conviction.

“And yet, with a little more material, we may prove that they are not insurmountable,” said Holmes. “I fancy that among your extensive archives, Watson, you may find some which were nearly as obscure. Meanwhile, we shall put the case aside until more accurate data are available, and devote the rest of our morning to the pursuit of neolithic man.”

I may have commented upon my friend’s power of mental detachment, but never have I wondered at it more than upon that spring morning in Cornwall when for two hours he discoursed upon celts, arrowheads, and shards, as lightly as if no sinister mystery were waiting for his solution. It was not until we had returned in the afternoon to our cottage that we found a visitor awaiting us, who soon brought our minds back to the matter in hand. Neither of us needed to be told who that visitor was. The huge body, the craggy and deeply seamed face with the fierce eyes and hawk-like nose, the grizzled hair which nearly brushed our cottage ceiling, the beard—golden at the fringes and white near the lips, save for the nicotine stain from his perpetual cigar—all these were as well known in London as in Africa, and could only be associated with the tremendous personality of Dr. Leon Sterndale, the great lion-hunter and explorer.

We had heard of his presence in the district and had once or twice caught sight of his tall figure upon the moorland paths. He made no advances to us, however, nor would we have dreamed of doing so to him, as it was well known that it was his love of seclusion which caused him to spend the greater part of the intervals between his journeys in a small bungalow buried in the lonely wood of Beauchamp Arriance. Here, amid his books and his maps, he lived an absolutely lonely life, attending to his own simple wants and paying little apparent heed to the affairs of his neighbours. It was a surprise to me, therefore, to hear him asking Holmes in an eager voice whether he had made any advance in his reconstruction of this mysterious episode. “The county police are utterly at fault,” said he, “but perhaps your wider experience has suggested some conceivable explanation. My only claim to being taken into your confidence is that during my many residences here I have come to know this family of Tregennis very well—indeed, upon my Cornish mother’s side I could call them cousins—and their strange fate has naturally been a great shock to me. I may tell you that I had got as far as Plymouth upon my way to Africa, but the news reached me this morning, and I came straight back again to help in the inquiry.”

Holmes raised his eyebrows.

“Did you lose your boat through it?”

“I will take the next.”

“Dear me! that is friendship indeed.”

“I tell you they were relatives.”

“Quite so—cousins of your mother. Was your baggage aboard the ship?”

“Some of it, but the main part at the hotel.”

“I see. But surely this event could not have found its way into the Plymouth morning papers.”

“No, sir; I had a telegram.”

“Might I ask from whom?”

A shadow passed over the gaunt face of the explorer.

“You are very inquisitive, Mr. Holmes.”

“It is my business.”

With an effort Dr. Sterndale recovered his ruffled composure.

“I have no objection to telling you,” he said. “It was Mr. Roundhay, the vicar, who sent me the telegram which recalled me.”

“Thank you,” said Holmes. “I may say in answer to your original question that I have not cleared my mind entirely on the subject of this case, but that I have every hope of reaching some conclusion. It would be premature to say more.”

“Perhaps you would not mind telling me if your suspicions point in any particular direction?”

“No, I can hardly answer that.”

“Then I have wasted my time and need not prolong my visit.” The famous doctor strode out of our cottage in considerable ill-humour, and within five minutes Holmes had followed him. I saw him no more until the evening, when he returned with a slow step and haggard face which assured me that he had made no great progress with his investigation. He glanced at a telegram which awaited him and threw it into the grate.

“From the Plymouth hotel, Watson,” he said. “I learned the name of it from the vicar, and I wired to make certain that Dr. Leon Sterndale’s account was true. It appears that he did indeed spend last night there, and that he has actually allowed some of his baggage to go on to Africa, while he returned to be present at this investigation. What do you make of that, Watson?”

“He is deeply interested.”

“Deeply interested—yes. There is a thread here which we had not yet grasped and which might lead us through the tangle. Cheer up, Watson, for I am very sure that our material has not yet all come to hand. When it does we may soon leave our difficulties behind us.”

Little did I think how soon the words of Holmes would be realised, or how strange and sinister would be that new development which opened up an entirely fresh line of investigation. I was shaving at my window in the morning when I heard the rattle of hoofs and, looking up, saw a dog-cart coming at a gallop down the road. It pulled up at our door, and our friend, the vicar, sprang from it and rushed up our garden path. Holmes was already dressed, and we hastened down to meet him.

Our visitor was so excited that he could hardly articulate, but at last in gasps and bursts his tragic story came out of him.

“We are devil-ridden, Mr. Holmes! My poor parish is devil-ridden!” he cried. “Satan himself is loose in it! We are given over into his hands!” He danced about in his agitation, a ludicrous object if it were not for his ashy face and startled eyes. Finally he shot out his terrible news.

“Mr. Mortimer Tregennis died during the night, and with exactly the same symptoms as the rest of his family.”

Holmes sprang to his feet, all energy in an instant.

“Can you fit us both into your dog-cart?”

“Yes, I can.”

“Then, Watson, we will postpone our breakfast. Mr. Roundhay, we are entirely at your disposal. Hurry—hurry, before things get disarranged.”

The lodger occupied two rooms at the vicarage, which were in an angle by themselves, the one above the other. Below was a large sitting-room; above, his bedroom. They looked out upon a croquet lawn which came up to the windows. We had arrived before the doctor or the police, so that everything was absolutely undisturbed. Let me describe exactly the scene as we saw it upon that misty March morning. It has left an impression which can never be effaced from my mind.

The atmosphere of the room was of a horrible and depressing stuffiness. The servant who had first entered had thrown up the window, or it would have been even more intolerable. This might partly be due to the fact that a lamp stood flaring and smoking on the centre table. Beside it sat the dead man, leaning back in his chair, his thin beard projecting, his spectacles pushed up on to his forehead, and his lean dark face turned towards the window and twisted into the same distortion of terror which had marked the features of his dead sister. His limbs were convulsed and his fingers contorted as though he had died in a very paroxysm of fear. He was fully clothed, though there were signs that his dressing had been done in a hurry. We had already learned that his bed had been slept in, and that the tragic end had come to him in the early morning.

One realised the red-hot energy which underlay Holmes’s phlegmatic exterior when one saw the sudden change which came over him from the moment that he entered the fatal apartment. In an instant he was tense and alert, his eyes shining, his face set, his limbs quivering with eager activity. He was out on the lawn, in through the window, round the room, and up into the bedroom, for all the world like a dashing foxhound drawing a cover. In the bedroom he made a rapid cast around and ended by throwing open the window, which appeared to give him some fresh cause for excitement, for he leaned out of it with loud ejaculations of interest and delight. Then he rushed down the stair, out through the open window, threw himself upon his face on the lawn, sprang up and into the room once more, all with the energy of the hunter who is at the very heels of his quarry. The lamp, which was an ordinary standard, he examined with minute care, making certain measurements upon its bowl. He carefully scrutinised with his lens the talc shield which covered the top of the chimney and scraped off some ashes which adhered to its upper surface, putting some of them into an envelope, which he placed in his pocketbook. Finally, just as the doctor and the official police put in an appearance, he beckoned to the vicar and we all three went out upon the lawn.

“I am glad to say that my investigation has not been entirely barren,” he remarked. “I cannot remain to discuss the matter with the police, but I should be exceedingly obliged, Mr. Roundhay, if you would give the inspector my compliments and direct his attention to the bedroom window and to the sitting-room lamp. Each is suggestive, and together they are almost conclusive. If the police would desire further information I shall be happy to see any of them at the cottage. And now, Watson, I think that, perhaps, we shall be better employed elsewhere.”

It may be that the police resented the intrusion of an amateur, or that they imagined themselves to be upon some hopeful line of investigation; but it is certain that we heard nothing from them for the next two days. During this time Holmes spent some of his time smoking and dreaming in the cottage; but a greater portion in country walks which he undertook alone, returning after many hours without remark as to where he had been. One experiment served to show me the line of his investigation. He had bought a lamp which was the duplicate of the one which had burned in the room of Mortimer Tregennis on the morning of the tragedy. This he filled with the same oil as that used at the vicarage, and he carefully timed the period which it would take to be exhausted. Another experiment which he made was of a more unpleasant nature, and one which I am not likely ever to forget.

“You will remember, Watson,” he remarked one afternoon, “that there is a single common point of resemblance in the varying reports which have reached us. This concerns the effect of the atmosphere of the room in each case upon those who had first entered it. You will recollect that Mortimer Tregennis, in describing the episode of his last visit to his brother’s house, remarked that the doctor on entering the room fell into a chair? You had forgotten? Well I can answer for it that it was so. Now, you will remember also that Mrs. Porter, the housekeeper, told us that she herself fainted upon entering the room and had afterwards opened the window. In the second case—that of Mortimer Tregennis himself—you cannot have forgotten the horrible stuffiness of the room when we arrived, though the servant had thrown open the window. That servant, I found upon inquiry, was so ill that she had gone to her bed. You will admit, Watson, that these facts are very suggestive. In each case there is evidence of a poisonous atmosphere. In each case, also, there is combustion going on in the room—in the one case a fire, in the other a lamp. The fire was needed, but the lamp was lit—as a comparison of the oil consumed will show—long after it was broad daylight. Why? Surely because there is some connection between three things—the burning, the stuffy atmosphere, and, finally, the madness or death of those unfortunate people. That is clear, is it not?”

“It would appear so.”

“At least we may accept it as a working hypothesis. We will suppose, then, that something was burned in each case which produced an atmosphere causing strange toxic effects. Very good. In the first instance—that of the Tregennis family—this substance was placed in the fire. Now the window was shut, but the fire would naturally carry fumes to some extent up the chimney. Hence one would expect the effects of the poison to be less than in the second case, where there was less escape for the vapour. The result seems to indicate that it was so, since in the first case only the woman, who had presumably the more sensitive organism, was killed, the others exhibiting that temporary or permanent lunacy which is evidently the first effect of the drug. In the second case the result was complete. The facts, therefore, seem to bear out the theory of a poison which worked by combustion.

“With this train of reasoning in my head I naturally looked about in Mortimer Tregennis’s room to find some remains of this substance. The obvious place to look was the talc shelf or smoke-guard of the lamp. There, sure enough, I perceived a number of flaky ashes, and round the edges a fringe of brownish powder, which had not yet been consumed. Half of this I took, as you saw, and I placed it in an envelope.”

“Why half, Holmes?”

“It is not for me, my dear Watson, to stand in the way of the official police force. I leave them all the evidence which I found. The poison still remained upon the talc had they the wit to find it. Now, Watson, we will light our lamp; we will, however, take the precaution to open our window to avoid the premature decease of two deserving members of society, and you will seat yourself near that open window in an armchair unless, like a sensible man, you determine to have nothing to do with the affair. Oh, you will see it out, will you? I thought I knew my Watson. This chair I will place opposite yours, so that we may be the same distance from the poison and face to face. The door we will leave ajar. Each is now in a position to watch the other and to bring the experiment to an end should the symptoms seem alarming. Is that all clear? Well, then, I take our powder—or what remains of it—from the envelope, and I lay it above the burning lamp. So! Now, Watson, let us sit down and await developments.”

They were not long in coming. I had hardly settled in my chair before I was conscious of a thick, musky odour, subtle and nauseous. At the very first whiff of it my brain and my imagination were beyond all control. A thick, black cloud swirled before my eyes, and my mind told me that in this cloud, unseen as yet, but about to spring out upon my appalled senses, lurked all that was vaguely horrible, all that was monstrous and inconceivably wicked in the universe. Vague shapes swirled and swam amid the dark cloud-bank, each a menace and a warning of something coming, the advent of some unspeakable dweller upon the threshold, whose very shadow would blast my soul. A freezing horror took possession of me. I felt that my hair was rising, that my eyes were protruding, that my mouth was opened, and my tongue like leather. The turmoil within my brain was such that something must surely snap. I tried to scream and was vaguely aware of some hoarse croak which was my own voice, but distant and detached from myself. At the same moment, in some effort of escape, I broke through that cloud of despair and had a glimpse of Holmes’s face, white, rigid, and drawn with horror—the very look which I had seen upon the features of the dead. It was that vision which gave me an instant of sanity and of strength. I dashed from my chair, threw my arms round Holmes, and together we lurched through the door, and an instant afterwards had thrown ourselves down upon the grass plot and were lying side by side, conscious only of the glorious sunshine which was bursting its way through the hellish cloud of terror which had girt us in. Slowly it rose from our souls like the mists from a landscape until peace and reason had returned, and we were sitting upon the grass, wiping our clammy foreheads, and looking with apprehension at each other to mark the last traces of that terrific experience which we had undergone.

“Upon my word, Watson!” said Holmes at last with an unsteady voice, “I owe you both my thanks and an apology. It was an unjustifiable experiment even for one’s self, and doubly so for a friend. I am really very sorry.”

“You know,” I answered with some emotion, for I have never seen so much of Holmes’s heart before, “that it is my greatest joy and privilege to help you.”

He relapsed at once into the half-humorous, half-cynical vein which was his habitual attitude to those about him. “It would be superfluous to drive us mad, my dear Watson,” said he. “A candid observer would certainly declare that we were so already before we embarked upon so wild an experiment. I confess that I never imagined that the effect could be so sudden and so severe.” He dashed into the cottage, and, reappearing with the burning lamp held at full arm’s length, he threw it among a bank of brambles. “We must give the room a little time to clear. I take it, Watson, that you have no longer a shadow of a doubt as to how these tragedies were produced?”

“None whatever.”

“But the cause remains as obscure as before. Come into the arbour here and let us discuss it together. That villainous stuff seems still to linger round my throat. I think we must admit that all the evidence points to this man, Mortimer Tregennis, having been the criminal in the first tragedy, though he was the victim in the second one. We must remember, in the first place, that there is some story of a family quarrel, followed by a reconciliation. How bitter that quarrel may have been, or how hollow the reconciliation we cannot tell. When I think of Mortimer Tregennis, with the foxy face and the small shrewd, beady eyes behind the spectacles, he is not a man whom I should judge to be of a particularly forgiving disposition. Well, in the next place, you will remember that this idea of someone moving in the garden, which took our attention for a moment from the real cause of the tragedy, emanated from him. He had a motive in misleading us. Finally, if he did not throw the substance into the fire at the moment of leaving the room, who did do so? The affair happened immediately after his departure. Had anyone else come in, the family would certainly have risen from the table. Besides, in peaceful Cornwall, visitors did not arrive after ten o’clock at night. We may take it, then, that all the evidence points to Mortimer Tregennis as the culprit.”

“Then his own death was suicide!”

“Well, Watson, it is on the face of it a not impossible supposition. The man who had the guilt upon his soul of having brought such a fate upon his own family might well be driven by remorse to inflict it upon himself. There are, however, some cogent reasons against it. Fortunately, there is one man in England who knows all about it, and I have made arrangements by which we shall hear the facts this afternoon from his own lips. Ah! he is a little before his time. Perhaps you would kindly step this way, Dr. Leon Sterndale. We have been conducing a chemical experiment indoors which has left our little room hardly fit for the reception of so distinguished a visitor.”

I had heard the click of the garden gate, and now the majestic figure of the great African explorer appeared upon the path. He turned in some surprise towards the rustic arbour in which we sat.

“You sent for me, Mr. Holmes. I had your note about an hour ago, and I have come, though I really do not know why I should obey your summons.”

“Perhaps we can clear the point up before we separate,” said Holmes. “Meanwhile, I am much obliged to you for your courteous acquiescence. You will excuse this informal reception in the open air, but my friend Watson and I have nearly furnished an additional chapter to what the papers call the Cornish Horror, and we prefer a clear atmosphere for the present. Perhaps, since the matters which we have to discuss will affect you personally in a very intimate fashion, it is as well that we should talk where there can be no eavesdropping.”

The explorer took his cigar from his lips and gazed sternly at my companion.

“I am at a loss to know, sir,” he said, “what you can have to speak about which affects me personally in a very intimate fashion.”

“The killing of Mortimer Tregennis,” said Holmes.

For a moment I wished that I were armed. Sterndale’s fierce face turned to a dusky red, his eyes glared, and the knotted, passionate veins started out in his forehead, while he sprang forward with clenched hands towards my companion. Then he stopped, and with a violent effort he resumed a cold, rigid calmness, which was, perhaps, more suggestive of danger than his hot-headed outburst.

“I have lived so long among savages and beyond the law,” said he, “that I have got into the way of being a law to myself. You would do well, Mr. Holmes, not to forget it, for I have no desire to do you an injury.”

“Nor have I any desire to do you an injury, Dr. Sterndale. Surely the clearest proof of it is that, knowing what I know, I have sent for you and not for the police.”

Sterndale sat down with a gasp, overawed for, perhaps, the first time in his adventurous life. There was a calm assurance of power in Holmes’s manner which could not be withstood. Our visitor stammered for a moment, his great hands opening and shutting in his agitation.

“What do you mean?” he asked at last. “If this is bluff upon your part, Mr. Holmes, you have chosen a bad man for your experiment. Let us have no more beating about the bush. What do you mean?”

“I will tell you,” said Holmes, “and the reason why I tell you is that I hope frankness may beget frankness. What my next step may be will depend entirely upon the nature of your own defence.”

“My defence?”

“Yes, sir.”

“My defence against what?”

“Against the charge of killing Mortimer Tregennis.”

Sterndale mopped his forehead with his handkerchief. “Upon my word, you are getting on,” said he. “Do all your successes depend upon this prodigious power of bluff?”

“The bluff,” said Holmes sternly, “is upon your side, Dr. Leon Sterndale, and not upon mine. As a proof I will tell you some of the facts upon which my conclusions are based. Of your return from Plymouth, allowing much of your property to go on to Africa, I will say nothing save that it first informed me that you were one of the factors which had to be taken into account in reconstructing this drama—”

“I came back—”

“I have heard your reasons and regard them as unconvincing and inadequate. We will pass that. You came down here to ask me whom I suspected. I refused to answer you. You then went to the vicarage, waited outside it for some time, and finally returned to your cottage.”

“How do you know that?”

“I followed you.”

“I saw no one.”

“That is what you may expect to see when I follow you. You spent a restless night at your cottage, and you formed certain plans, which in the early morning you proceeded to put into execution. Leaving your door just as day was breaking, you filled your pocket with some reddish gravel that was lying heaped beside your gate.”

Sterndale gave a violent start and looked at Holmes in amazement.

“You then walked swiftly for the mile which separated you from the vicarage. You were wearing, I may remark, the same pair of ribbed tennis shoes which are at the present moment upon your feet. At the vicarage you passed through the orchard and the side hedge, coming out under the window of the lodger Tregennis. It was now daylight, but the household was not yet stirring. You drew some of the gravel from your pocket, and you threw it up at the window above you.”

Sterndale sprang to his feet.

“I believe that you are the devil himself!” he cried.

Holmes smiled at the compliment. “It took two, or possibly three, handfuls before the lodger came to the window. You beckoned him to come down. He dressed hurriedly and descended to his sitting-room. You entered by the window. There was an interview—a short one—during which you walked up and down the room. Then you passed out and closed the window, standing on the lawn outside smoking a cigar and watching what occurred. Finally, after the death of Tregennis, you withdrew as you had come. Now, Dr. Sterndale, how do you justify such conduct, and what were the motives for your actions? If you prevaricate or trifle with me, I give you my assurance that the matter will pass out of my hands forever.”

Our visitor’s face had turned ashen grey as he listened to the words of his accuser. Now he sat for some time in thought with his face sunk in his hands. Then with a sudden impulsive gesture he plucked a photograph from his breast-pocket and threw it on the rustic table before us.

“That is why I have done it,” said he.

It showed the bust and face of a very beautiful woman. Holmes stooped over it.

“Brenda Tregennis,” said he.

“Yes, Brenda Tregennis,” repeated our visitor. “For years I have loved her. For years she has loved me. There is the secret of that Cornish seclusion which people have marvelled at. It has brought me close to the one thing on earth that was dear to me. I could not marry her, for I have a wife who has left me for years and yet whom, by the deplorable laws of England, I could not divorce. For years Brenda waited. For years I waited. And this is what we have waited for.” A terrible sob shook his great frame, and he clutched his throat under his brindled beard. Then with an effort he mastered himself and spoke on:

“The vicar knew. He was in our confidence. He would tell you that she was an angel upon earth. That was why he telegraphed to me and I returned. What was my baggage or Africa to me when I learned that such a fate had come upon my darling? There you have the missing clue to my action, Mr. Holmes.”

“Proceed,” said my friend.

Dr. Sterndale drew from his pocket a paper packet and laid it upon the table. On the outside was written “Radix pedis diaboli” with a red poison label beneath it. He pushed it towards me. “I understand that you are a doctor, sir. Have you ever heard of this preparation?”

“Devil’s-foot root! No, I have never heard of it.”

“It is no reflection upon your professional knowledge,” said he, “for I believe that, save for one sample in a laboratory at Buda, there is no other specimen in Europe. It has not yet found its way either into the pharmacopœia or into the literature of toxicology. The root is shaped like a foot, half human, half goatlike; hence the fanciful name given by a botanical missionary. It is used as an ordeal poison by the medicine-men in certain districts of West Africa and is kept as a secret among them. This particular specimen I obtained under very extraordinary circumstances in the Ubangi country.” He opened the paper as he spoke and disclosed a heap of reddish-brown, snuff-like powder.

“Well, sir?” asked Holmes sternly.

“I am about to tell you, Mr. Holmes, all that actually occurred, for you already know so much that it is clearly to my interest that you should know all. I have already explained the relationship in which I stood to the Tregennis family. For the sake of the sister I was friendly with the brothers. There was a family quarrel about money which estranged this man Mortimer, but it was supposed to be made up, and I afterwards met him as I did the others. He was a sly, subtle, scheming man, and several things arose which gave me a suspicion of him, but I had no cause for any positive quarrel.

“One day, only a couple of weeks ago, he came down to my cottage and I showed him some of my African curiosities. Among other things I exhibited this powder, and I told him of its strange properties, how it stimulates those brain centres which control the emotion of fear, and how either madness or death is the fate of the unhappy native who is subjected to the ordeal by the priest of his tribe. I told him also how powerless European science would be to detect it. How he took it I cannot say, for I never left the room, but there is no doubt that it was then, while I was opening cabinets and stooping to boxes, that he managed to abstract some of the devil’s-foot root. I well remember how he plied me with questions as to the amount and the time that was needed for its effect, but I little dreamed that he could have a personal reason for asking.

“I thought no more of the matter until the vicar’s telegram reached me at Plymouth. This villain had thought that I would be at sea before the news could reach me, and that I should be lost for years in Africa. But I returned at once. Of course, I could not listen to the details without feeling assured that my poison had been used. I came round to see you on the chance that some other explanation had suggested itself to you. But there could be none. I was convinced that Mortimer Tregennis was the murderer; that for the sake of money, and with the idea, perhaps, that if the other members of his family were all insane he would be the sole guardian of their joint property, he had used the devil’s-foot powder upon them, driven two of them out of their senses, and killed his sister Brenda, the one human being whom I have ever loved or who has ever loved me. There was his crime; what was to be his punishment?

“Should I appeal to the law? Where were my proofs? I knew that the facts were true, but could I help to make a jury of countrymen believe so fantastic a story? I might or I might not. But I could not afford to fail. My soul cried out for revenge. I have said to you once before, Mr. Holmes, that I have spent much of my life outside the law, and that I have come at last to be a law to myself. So it was even now. I determined that the fate which he had given to others should be shared by himself. Either that or I would do justice upon him with my own hand. In all England there can be no man who sets less value upon his own life than I do at the present moment.

“Now I have told you all. You have yourself supplied the rest. I did, as you say, after a restless night, set off early from my cottage. I foresaw the difficulty of arousing him, so I gathered some gravel from the pile which you have mentioned, and I used it to throw up to his window. He came down and admitted me through the window of the sitting-room. I laid his offence before him. I told him that I had come both as judge and executioner. The wretch sank into a chair, paralysed at the sight of my revolver. I lit the lamp, put the powder above it, and stood outside the window, ready to carry out my threat to shoot him should he try to leave the room. In five minutes he died. My God! how he died! But my heart was flint, for he endured nothing which my innocent darling had not felt before him. There is my story, Mr. Holmes. Perhaps, if you loved a woman, you would have done as much yourself. At any rate, I am in your hands. You can take what steps you like. As I have already said, there is no man living who can fear death less than I do.”

Holmes sat for some little time in silence.

“What were your plans?” he asked at last.

“I had intended to bury myself in central Africa. My work there is but half finished.”

“Go and do the other half,” said Holmes. “I, at least, am not prepared to prevent you.”

Dr. Sterndale raised his giant figure, bowed gravely, and walked from the arbour. Holmes lit his pipe and handed me his pouch.

“Some fumes which are not poisonous would be a welcome change,” said he. “I think you must agree, Watson, that it is not a case in which we are called upon to interfere. Our investigation has been independent, and our action shall be so also. You would not denounce the man?”

“Certainly not,” I answered.

“I have never loved, Watson, but if I did and if the woman I loved had met such an end, I might act even as our lawless lion-hunter has done. Who knows? Well, Watson, I will not offend your intelligence by explaining what is obvious. The gravel upon the window-sill was, of course, the starting-point of my research. It was unlike anything in the vicarage garden. Only when my attention had been drawn to Dr. Sterndale and his cottage did I find its counterpart. The lamp shining in broad daylight and the remains of powder upon the shield were successive links in a fairly obvious chain. And now, my dear Watson, I think we may dismiss the matter from our mind and go back with a clear conscience to the study of those Chaldean roots which are surely to be traced in the Cornish branch of the great Celtic speech.”
