"When I came to examine the address of the packet I observed that it was to Miss S. Cushing. Now, the oldest sister would, of course, be Miss Cushing, and although her initial was 'S' it might belong to one of the others as well. In that case we should have to commence our investigation from a fresh basis altogether. I therefore went into the house with the intention of clearing up this point. I was about to assure Miss Cushing that I was convinced that a mistake had been made when you may remember that I came suddenly to a stop. The fact was that I had just seen something which filled me with surprise and at the same time narrowed the field of our inquiry immensely.
   "As a medical man, you are aware, Watson, that there is no part of the body which varies so much as the human ear. Each ear is as a rule quite distinctive and differs from all other ones. In last year's Anthropological Journal you will find two short monographs from my pen upon the subject. I had, therefore, examined the ears in the box with the eyes of an expert and had carefully noted their anatomical peculiarities. Imagine my surprise, then, when on looking at Miss Cushing I perceived that her ear corresponded exactly with the female ear which I had just inspected. The matter was entirely beyond coincidence. There was the same shortening of the pinna, the same broad curve of the upper lobe, the same convolution of the inner cartilage. In all essentials it was the same ear.
   "Of course I at once saw the enormous importance of the observation. It was evident that the victim was a blood relation and probably a very close one. I began to talk to her about her family, and you remember that she at once gave us some exceedingly valuable details
   "In the first place, her sister's name was Sarah, and her address had until recently been the same, so that it was quite obvious how the mistake had occurred and for whom the packet was meant. Then we heard of this steward, married to the third sister, and learned that he had at one time been so intimate with Miss Sarah that she had actually gone up to Liverpool to be near the Browners, but a quarrel had afterwards divided them. This quarrel had put a stop to all communications for some months, so that if Browner had occasion to address a packet to Miss Sarah, he would undoubtedly have done so to her old address.
   "And now the matter had begun to straighten itself out wonderfully. We had learned of the existence of this steward, an impulsive man, of strong passions – you remember that he threw up what must have been a very superior berth in order to be nearer to his wife – subject, too, to occasional fits of hard drinking. We had reason to believe that his wife had been murdered, and that a man – presumably a seafaring man – had been murdered at the same time. Jealousy, of course, at once suggests itself as the motive for the crime. And why should these proofs of the deed be sent to Miss Sarah Cushing? Probably because during her residence in Liverpool she had some hand in bringing about the events which led to the tragedy. You will observe that this line of boats calls at Belfast, Dublin, and Waterford; so that, presuming that Browner had committed the deed and had embarked at once upon his steamer, the May Day, Belfast would be the first place at which he could post his terrible packet.
   "A second solution was at this stage obviously possible, and although I thought it exceedingly unlikely, I was determined to elucidate it before going further. An unsuccessful lover might have killed Mr. and Mrs. Browner, and the male ear might have belonged to the husband. There were many grave objections to this theory, but it was conceivable. I therefore sent off a telegram to my friend Algar, of the Liverpool force, and asked him to find out if Mrs. Browner were at home, and if Browner had departed in the May Day. Then we went on to Wallington to visit Miss Sarah.
   "I was curious, in the first place, to see how far the family ear had been reproduced in her. Then, of course, she might give us very important information, but I was not sanguine that she would. She must have heard of the business the day before, since all Croydon was ringing with it, and she alone could have understood for whom the packet was meant. If she had been willing to help justice she would probably have communicated with the police already. However, it was clearly our duty to see her, so we went. We found that the news of the arrival of the packet – for her illness dated from that time – had such an effect upon her as to bring on brain fever. It was clearer than ever that she understood its full significance, but equally clear that we should have to wait some time for any assistance from her.
   "However, we were really independent of her help. Our answers were waiting for us at the police-station, where I had directed Algar to send them. Nothing could be more conclusive. Mrs. Browner's house had been closed for more than three days, and the neighbors were of opinion that she had gone south to see her relatives. It had been ascertained at the shipping offices that Browner had left aboard of the May Day, and I calculate that she is due in the Thames tomorrow night. When he arrives he will be met by the obtuse but resolute Lestrade, and I have no doubt that we shall have all our details filled in."
   Sherlock Holmes was not disappointed in his expectations. Two days later he received a bulky envelope, which contained a short note from the detective, and a typewritten document, which covered several pages of foolscap.
   "Lestrade has got him all right," said Holmes, glancing up at me. "Perhaps it would interest you to hear what he says.
   "MY DEAR MR. HOLMES:
   "In accordance with the scheme which we had formed in
   order to test our theories, …"
 
   "… I went down to the Albert Dock yesterday
   at 6 P. M., and boarded the S. S. May Day, belonging to the
   Liverpool, Dublin, and London Steam Packet Company. On
   inquiry, I found that there was a steward on board of the
   name of James Browner and that he had acted during
   the voyage in such an extraordinary manner that the captain
   had been compelled to relieve him of his duties. On de-
   scending to his berth, I found him seated upon a chest with
   his head sunk upon his hands, rocking himself to and fro.
   He is a big, powerful chap, clean-shaven, and very swarthy —
   something like Aldridge, who helped us in the bogus laun-
   dry affair. He jumped up when he heard my business, and I
   had my whistle to my lips to call a couple of river police,
   who were round the corner, but he seemed to have no heart
   in him, and he held out his hands quietly enough for the
   darbies. We brought him along to the cells, and his box as
   well, for we thought there might be something incriminat-
   ing; but, bar a big sharp knife such as most sailors have, we
   got nothing for our trouble. However, we find that we shall
   want no more evidence, for on being brought before the
   inspector at the station he asked leave to make a statement,
   which was, of course, taken down, just as he made it, by
   our shorthand man. We had three copies typewritten, one of
   which I enclose. The affair proves, as I always thought it
   would, to be an extremely simple one, but I am obliged to
   you for assisting me in my investigation. With kind regards,
   "Yours very truly,
   "G. LESTRADE"
   "Hum! The investigation really was a very simple one," remarked Holmes, "but I don't think it struck him in that light when he first called us in. However, let us see what Jim Browner has to say for himself. This is his statement as made before Inspector Montgomery at the Shadwell Police Station, and it has the advantage of being verbatim."
   " 'Have I anything to say? Yes, I have a deal to say. I have to make a clean breast of it all. You can hang me, or you can leave me alone. I don't care a plug which you do. I tell you I've not shut an eye in sleep since I did it, and I don't believe I ever will again until I get past all waking. Sometimes it's his face, but most generally it's hers. I'm never without one or the other before me. He looks frowning and black-like, but she has a kind o' surprise upon her face. Ay, the white lamb, she might well be surprised when she read death on a face that had seldom looked anything but love upon her before.
   " 'But it was Sarah's fault, and may the curse of a broken man put a blight on her and set the blood rotting in her veins! It's not that I want to clear myself. I know that I went back to drink, like the beast that I was. But she would have forgiven me; she would have stuck as close to me as a rope to a block if that woman had never darkened our door. For Sarah Cushing loved me – that's the root of the business – she loved me until all her love turned to poisonous hate when she knew that I thought more of my wife's footmark in the mud than I did of her whole body and soul.
   " 'There were three sisters altogether. The old one was just a good woman, the second was a devil, and the third was an angel. Sarah was thirty-three, and Mary was twenty-nine when I married. We were just as happy as the day was long when we set up house together, and in all Liverpool there was no better woman than my Mary. And then we asked Sarah up for a week, and the week grew into a month, and one thing led to another, until she was just one of ourselves.
   " 'I was blue ribbon at that time, and we were putting a little money by, and all was as bright as a new dollar. My God, whoever would have thought that it could have come to this? Whoever would have dreamed it?
   " 'I used to be home for the weekends very often, and sometimes if the ship were held back for cargo I would have a whole week at a time, and in this way I saw a deal of my sister-in-law, Sarah. She was a fine tall woman, black and quick and fierce, with a proud way of carrying her head, and a glint from her eye like a spark from a flint. But when little Mary was there I had never a thought of her, and that I swear as I hope for God's mercy.
   " 'It had seemed to me sometimes that she liked to be alone with me, or to coax me out for a walk with her, but I had never thought anything of that. But one evening my eyes were opened. I had come up from the ship and found my wife out, but Sarah at home. "Where's Mary?" I asked. "Oh, she has gone to pay some accounts." I was impatient and paced up and down the room. "Can't you be happy for five minutes without Mary, Jim?" says she. "It's a bad compliment to me that you can't be contented with my society for so short a time." "That's all right, my lass," said I, putting out my hand towards her in a kindly way, but she had it in both hers in an instant, and they burned as if they were in a fever. I looked into her eyes and I read it all there. There was no need for her to speak, nor for me either. I frowned and drew my hand away. Then she stood by my side in silence for a bit, and then put up her hand and patted me on the shoulder. "Steady old Jim!" said she, and with a kind o' mocking laugh, she ran out of the room.
   " 'Well, from that time Sarah hated me with her whole heart and soul, and she is a woman who can hate, too. I was a fool to let her go on biding with us – a besotted fool – but I never said a word to Mary, for I knew it would grieve her. Things went on much as before, but after a time I began to find that there was a bit of a change in Mary herself. She had always been so trusting and so innocent, but now she became queer and suspicious, wanting to know where I had been and what I had been doing, and whom my letters were from, and what I had in my pockets, and a thousand such follies. Day by day she grew queerer and more irritable, and we had ceaseless rows about nothing. I was fairly puzzled by it all. Sarah avoided me now, but she and Mary were just inseparable. I can see now how she was plotting and scheming and poisoning my wife's mind against me, but I was such a blind beetle that I could not understand it at the time. Then I broke my blue ribbon and began to drink again, but I think I should not have done it if Mary had been the same as ever. She had some reason to be disgusted with me now, and the gap between us began to be wider and wider. And then this Alec Fairbairn chipped in, and things became a thousand times blacker.
   " 'It was to see Sarah that he came to my house first, but soon it was to see us, for he was a man with winning ways, and he made friends wherever he went. He was a dashing, swaggering chap, smart and curled, who had seen half the world and could talk of what he had seen. He was good company, I won't deny it, and he had wonderful polite ways with him for a sailor man, so that I think there must have been a time when he knew more of the poop than the forecastle. For a month he was in and out of my house, and never once did it cross my mind that harm might come of his soft, tricky ways. And then at last something made me suspect, and from that day my peace was gone forever.
   " 'It was only a little thing, too. I had come into the parlor unexpected, and as I walked in at the door I saw a light of welcome on my wife's face. But as she saw who it was it faded again, and she turned away with a look of disappointment. That was enough for me. There was no one but Alec Fairbairn whose step she could have mistaken for mine. If I could have seen him then I should have killed him, for I have always been like a madman when my temper gets loose. Mary saw the devil's light in my eyes, and she ran forward with her hands on my sleeve. "Don't, Jim, don't!" says she. "Where's Sarah?" I asked. "In the kitchen," says she. "Sarah," says I as I went in, "this man Fairbairn is never to darken my door again." "Why not?" says she. "Because I order it." "Oh!" says she, "if my friends are not good enough for this house, then I am not good enough for it either." "You can do what you like," says I, "but if Fairbairn shows his face here again I'll send you one of his ears for a keepsake." She was frightened by my face, I think, for she never answered a word, and the same evening she left my house.
   " 'Well, I don't know now whether it was pure deviltry on the part of this woman, or whether she thought that she could turn me against my wife by encouraging her to misbehave. Anyway, she took a house just two streets off and let lodgings to sailors. Fairbairn used to stay there, and Mary would go round to have tea with her sister and him. How often she went I don't know, but I followed her one day, and as I broke in at the door Fairbairn got away over the back garden wall, like the cowardly skunk that he was. I swore to my wife that I would kill her if I found her in his company again, and I led her back with me, sobbing and trembling, and as white as a piece of paper. There was no trace of love between us any longer. I could see that she hated me and feared me, and when the thought of it drove me to drink, then she despised me as well.
   " 'Well, Sarah found that she could not make a living in Liverpool, so she went back, as I understand, to live with her sister in Croydon, and things jogged on much the same as ever at home. And then came this last week and all the misery and ruin.
   " 'It was in this way. We had gone on the May Day for a round voyage of seven days, but a hogshead got loose and started one of our plates, so that we had to put back into port for twelve hours. I left the ship and came home, thinking what a surprise it would be for my wife, and hoping that maybe she would be glad to see me so soon. The thought was in my head as I turned into my own street, and at that moment a cab passed me, and there she was, sitting by the side of Fairbairn, the two chatting and laughing, with never a thought for me as I stood watching them from the footpath.
   " 'I tell you, and I give you my word for it, that from that moment I was not my own master, and it is all like a dim dream when I look back on it. I had been drinking hard of late, and the two things together fairly turned my brain. There's something throbbing in my head now, like a docker's hammer, but that morning I seemed to have all Niagara whizzing and buzzing in my ears.
   " 'Well, I took to my heels, and l ran after the cab. I had a heavy oak stick in my hand, and I tell you I saw red from the first; but as I ran I got cunning, too, and hung back a little to see them without being seen. They pulled up soon at the railway station. There was a good crowd round the booking-office, so I got quite close to them without being seen. They took tickets for New Brighton. So did I, but I got in three carriages behind them. When we reached it they walked along the Parade, and I was never more than a hundred yards from them. At last I saw them hire a boat and start for a row, for it was a very hot day, and they thought, no doubt, that it would be cooler on the water.
   " 'It was just as if they had been given into my hands. There was a bit of a haze, and you could not see more than a few hundred yards. I hired a boat for myself, and I pulled after them. I could see the blur of their craft, but they were going nearly as fast as I, and they must have been a long mile from the shore before I caught them up. The haze was like a curtain all round us, and there were we three in the middle of it. My God, shall I ever forget their faces when they saw who was in the boat that was closing in upon them? She screamed out. He swore like a madman and jabbed at me with an oar, for he must have seen death in my eyes. I got past it and got one in with my stick that crushed his head like an egg. I would have spared her, perhaps, for all my madness, but she threw her arms round him, crying out to him, and calling him "Alec." I struck again, and she lay stretched beside him. I was like a wild beast then that had tasted blood. If Sarah had been there, by the Lord, she should have joined them. I pulled out my knife, and – well, there! I've said enough. It gave me a kind of savage joy when I thought how Sarah would feel when she had such signs as these of what her meddling had brought about. Then I tied the bodies into the boat, stove a plank, and stood by until they had sunk. I knew very well that the owner would think that they had lost their bearings in the haze, and had drifted off out to sea. I cleaned myself up, got back to land, and joined my ship without a soul having a suspicion of what had passed. That night I made up the packet for Sarah Cushing, and next day I sent it from Belfast.
   " 'There you have the whole truth of it. You can hang me, or do what you like with me, but you cannot punish me as I have been punished already. I cannot shut my eyes but I see those two faces staring at me – staring at me as they stared when my boat broke through the haze. I killed them quick, but they are killing me slow; and if I have another night of it I shall be either mad or dead before morning. You won't put me alone into a cell, sir? For pity's sake don't, and may you be treated in your day of agony as you treat me now.'
   "What is the meaning of it, Watson?" said Holmes solemnly as he laid down the paper. "What object is served by this circle of misery and violence and fear? It must tend to some end, or else our universe is ruled by chance, which is unthinkable. But what end? There is the great standing perennial problem to which human reason is as far from an answer as ever."

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 windowpanes, 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 of 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 somber 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 tramcar 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 honor 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 specialty 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 pigeonholed 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 today. 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 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 neighboring 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 traveling 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 checkbook 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 beehive. 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 mйtier. No, you are the one man who can clear the matter up. If you have a fancy to see your name in the next honors 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 subtitles fill two lines of a book of reference. He has grown gray in the service, is a gentleman, a favored 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 draftsman, 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 hotheaded 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 traveling back to Woolwich when he was killed and thrown out of the compartment."
   "Aldgate, where the body was found, is considerably past the station for 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 theater, escorted his fiancee 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 favor 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; there 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-colored 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 unraveling 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."
