His Last Bow

"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 fiancee, 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 the 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 also is 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-gray, 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 burglarproof 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 gray 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 impetuous, but a straight, honest man. We have nothing against him. He was next to 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 the plans up 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."
