Chapter II: Front Matter (2)

“Excellent, Warner!” cried Holmes, springing to his feet. “Watson, the gaps are closing rapidly.”

In the cab was a woman, half-collapsed from nervous exhaustion. She bore upon her aquiline and emaciated face the traces of some recent tragedy. Her head hung listlessly upon her breast, but as she raised it and turned her dull eyes upon us I saw that her pupils were dark dots in the centre of the broad grey iris. She was drugged with opium.

“I watched at the gate, same as you advised, Mr. Holmes,” said our emissary, the discharged gardener. “When the carriage came out I followed it to the station. She was like one walking in her sleep, but when they tried to get her into the train she came to life and struggled. They pushed her into the carriage. She fought her way out again. I took her part, got her into a cab, and here we are. I shan’t forget the face at the carriage window as I led her away. I’d have a short life if he had his way—the black-eyed, scowling, yellow devil.”

We carried her upstairs, laid her on the sofa, and a couple of cups of the strongest coffee soon cleared her brain from the mists of the drug. Baynes had been summoned by Holmes, and the situation rapidly explained to him.

“Why, sir, you’ve got me the very evidence I want,” said the inspector warmly, shaking my friend by the hand. “I was on the same scent as you from the first.”

“What! You were after Henderson?”

“Why, Mr. Holmes, when you were crawling in the shrubbery at High Gable I was up one of the trees in the plantation and saw you down below. It was just who would get his evidence first.”

“Then why did you arrest the mulatto?”

Baynes chuckled.

“I was sure Henderson, as he calls himself, felt that he was suspected, and that he would lie low and make no move so long as he thought he was in any danger. I arrested the wrong man to make him believe that our eyes were off him. I knew he would be likely to clear off then and give us a chance of getting at Miss Burnet.”

Holmes laid his hand upon the inspector’s shoulder.

“You will rise high in your profession. You have instinct and intuition,” said he.

Baynes flushed with pleasure.

“I’ve had a plain-clothes man waiting at the station all the week. Wherever the High Gable folk go he will keep them in sight. But he must have been hard put to it when Miss Burnet broke away. However, your man picked her up, and it all ends well. We can’t arrest without her evidence, that is clear, so the sooner we get a statement the better.”

“Every minute she gets stronger,” said Holmes, glancing at the governess. “But tell me, Baynes, who is this man Henderson?”

“Henderson,” the inspector answered, “is Don Murillo, once called the Tiger of San Pedro.”

The Tiger of San Pedro! The whole history of the man came back to me in a flash. He had made his name as the most lewd and bloodthirsty tyrant that had ever governed any country with a pretence to civilization. Strong, fearless, and energetic, he had sufficient virtue to enable him to impose his odious vices upon a cowering people for ten or twelve years. His name was a terror through all Central America. At the end of that time there was a universal rising against him. But he was as cunning as he was cruel, and at the first whisper of coming trouble he had secretly conveyed his treasures aboard a ship which was manned by devoted adherents. It was an empty palace which was stormed by the insurgents next day. The dictator, his two children, his secretary, and his wealth had all escaped them. From that moment he had vanished from the world, and his identity had been a frequent subject for comment in the European press.

“Yes, sir, Don Murillo, the Tiger of San Pedro,” said Baynes. “If you look it up you will find that the San Pedro colours are green and white, same as in the note, Mr. Holmes. Henderson he called himself, but I traced him back, Paris and Rome and Madrid to Barcelona, where his ship came in in ’86. They’ve been looking for him all the time for their revenge, but it is only now that they have begun to find him out.”

“They discovered him a year ago,” said Miss Burnet, who had sat up and was now intently following the conversation. “Once already his life has been attempted, but some evil spirit shielded him. Now, again, it is the noble, chivalrous Garcia who has fallen, while the monster goes safe. But another will come, and yet another, until some day justice will be done; that is as certain as the rise of to-morrow’s sun.” Her thin hands clenched, and her worn face blanched with the passion of her hatred.

“But how come you into this matter, Miss Burnet?” asked Holmes. “How can an English lady join in such a murderous affair?”

“I join in it because there is no other way in the world by which justice can be gained. What does the law of England care for the rivers of blood shed years ago in San Pedro, or for the shipload of treasure which this man has stolen? To you they are like crimes committed in some other planet. But _we_ know. We have learned the truth in sorrow and in suffering. To us there is no fiend in hell like Juan Murillo, and no peace in life while his victims still cry for vengeance.”

“No doubt,” said Holmes, “he was as you say. I have heard that he was atrocious. But how are you affected?”

“I will tell you it all. This villain’s policy was to murder, on one pretext or another, every man who showed such promise that he might in time come to be a dangerous rival. My husband—yes, my real name is Signora Victor Durando—was the San Pedro minister in London. He met me and married me there. A nobler man never lived upon earth. Unhappily, Murillo heard of his excellence, recalled him on some pretext, and had him shot. With a premonition of his fate he had refused to take me with him. His estates were confiscated, and I was left with a pittance and a broken heart.

“Then came the downfall of the tyrant. He escaped as you have just described. But the many whose lives he had ruined, whose nearest and dearest had suffered torture and death at his hands, would not let the matter rest. They banded themselves into a society which should never be dissolved until the work was done. It was my part after we had discovered in the transformed Henderson the fallen despot, to attach myself to his household and keep the others in touch with his movements. This I was able to do by securing the position of governess in his family. He little knew that the woman who faced him at every meal was the woman whose husband he had hurried at an hour’s notice into eternity. I smiled on him, did my duty to his children, and bided my time. An attempt was made in Paris and failed. We zig-zagged swiftly here and there over Europe to throw off the pursuers and finally returned to this house, which he had taken upon his first arrival in England.

“But here also the ministers of justice were waiting. Knowing that he would return there, Garcia, who is the son of the former highest dignitary in San Pedro, was waiting with two trusty companions of humble station, all three fired with the same reasons for revenge. He could do little during the day, for Murillo took every precaution and never went out save with his satellite Lucas, or Lopez as he was known in the days of his greatness. At night, however, he slept alone, and the avenger might find him. On a certain evening, which had been prearranged, I sent my friend final instructions, for the man was forever on the alert and continually changed his room. I was to see that the doors were open and the signal of a green or white light in a window which faced the drive was to give notice if all was safe or if the attempt had better be postponed.

“But everything went wrong with us. In some way I had excited the suspicion of Lopez, the secretary. He crept up behind me and sprang upon me just as I had finished the note. He and his master dragged me to my room and held judgment upon me as a convicted traitress. Then and there they would have plunged their knives into me could they have seen how to escape the consequences of the deed. Finally, after much debate, they concluded that my murder was too dangerous. But they determined to get rid forever of Garcia. They had gagged me, and Murillo twisted my arm round until I gave him the address. I swear that he might have twisted it off had I understood what it would mean to Garcia. Lopez addressed the note which I had written, sealed it with his sleeve-link, and sent it by the hand of the servant, José. How they murdered him I do not know, save that it was Murillo’s hand who struck him down, for Lopez had remained to guard me. I believe he must have waited among the gorse bushes through which the path winds and struck him down as he passed. At first they were of a mind to let him enter the house and to kill him as a detected burglar; but they argued that if they were mixed up in an inquiry their own identity would at once be publicly disclosed and they would be open to further attacks. With the death of Garcia, the pursuit might cease, since such a death might frighten others from the task.

“All would now have been well for them had it not been for my knowledge of what they had done. I have no doubt that there were times when my life hung in the balance. I was confined to my room, terrorised by the most horrible threats, cruelly ill-used to break my spirit—see this stab on my shoulder and the bruises from end to end of my arms—and a gag was thrust into my mouth on the one occasion when I tried to call from the window. For five days this cruel imprisonment continued, with hardly enough food to hold body and soul together. This afternoon a good lunch was brought me, but the moment after I took it I knew that I had been drugged. In a sort of dream I remember being half-led, half-carried to the carriage; in the same state I was conveyed to the train. Only then, when the wheels were almost moving, did I suddenly realise that my liberty lay in my own hands. I sprang out, they tried to drag me back, and had it not been for the help of this good man, who led me to the cab, I should never had broken away. Now, thank God, I am beyond their power forever.”

We had all listened intently to this remarkable statement. It was Holmes who broke the silence.

“Our difficulties are not over,” he remarked, shaking his head. “Our police work ends, but our legal work begins.”

“Exactly,” said I. “A plausible lawyer could make it out as an act of self-defence. There may be a hundred crimes in the background, but it is only on this one that they can be tried.”

“Come, come,” said Baynes cheerily, “I think better of the law than that. Self-defence is one thing. To entice a man in cold blood with the object of murdering him is another, whatever danger you may fear from him. No, no, we shall all be justified when we see the tenants of High Gable at the next Guildford Assizes.”

It is a matter of history, however, that a little time was still to elapse before the Tiger of San Pedro should meet with his deserts. Wily and bold, he and his companion threw their pursuer off their track by entering a lodging-house in Edmonton Street and leaving by the back-gate into Curzon Square. From that day they were seen no more in England. Some six months afterwards the Marquess of Montalva and Signor Rulli, his secretary, were both murdered in their rooms at the Hotel Escurial at Madrid. The crime was ascribed to Nihilism, and the murderers were never arrested. Inspector Baynes visited us at Baker Street with a printed description of the dark face of the secretary, and of the masterful features, the magnetic black eyes, and the tufted brows of his master. We could not doubt that justice, if belated, had come at last.

“A chaotic case, my dear Watson,” said Holmes over an evening pipe. “It will not be possible for you to present in that compact form which is dear to your heart. It covers two continents, concerns two groups of mysterious persons, and is further complicated by the highly respectable presence of our friend, Scott Eccles, whose inclusion shows me that the deceased Garcia had a scheming mind and a well-developed instinct of self-preservation. It is remarkable only for the fact that amid a perfect jungle of possibilities we, with our worthy collaborator, the inspector, have kept our close hold on the essentials and so been guided along the crooked and winding path. Is there any point which is not quite clear to you?”

“The object of the mulatto cook’s return?”

“I think that the strange creature in the kitchen may account for it. The man was a primitive savage from the backwoods of San Pedro, and this was his fetish. When his companion and he had fled to some prearranged retreat—already occupied, no doubt by a confederate—the companion had persuaded him to leave so compromising an article of furniture. But the mulatto’s heart was with it, and he was driven back to it next day, when, on reconnoitering through the window, he found policeman Walters in possession. He waited three days longer, and then his piety or his superstition drove him to try once more. Inspector Baynes, who, with his usual astuteness, had minimised the incident before me, had really recognised its importance and had left a trap into which the creature walked. Any other point, Watson?”

“The torn bird, the pail of blood, the charred bones, all the mystery of that weird kitchen?”

Holmes smiled as he turned up an entry in his note-book.

“I spent a morning in the British Museum reading up on that and other points. Here is a quotation from Eckermann’s _Voodooism and the Negroid Religions:_

“‘The true voodoo-worshipper attempts nothing of importance without certain sacrifices which are intended to propitiate his unclean gods. In extreme cases these rites take the form of human sacrifices followed by cannibalism. The more usual victims are a white cock, which is plucked in pieces alive, or a black goat, whose throat is cut and body burned.’

“So you see our savage friend was very orthodox in his ritual. It is grotesque, Watson,” Holmes added, as he slowly fastened his notebook, “but, as I have had occasion to remark, there is but one step from the grotesque to the horrible.”

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.

“Must see you over Cadogan West. Coming at once.” MYCROFT.

“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 métier. 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.
