mutilated by an expanding revolver bullet, but no weapon of

  any sort was to be found in the room. On the table lay two

  bank-notes for ten pounds each and seventeen pounds ten in

  silver and gold, the money arranged in little piles of

  varying amount. There were some figures also upon a sheet

  of paper with the names of some club friends opposite to

  them, from which it was conjectured that before his death

  he was endeavouring to make out his losses or winnings at

  cards.

  A minute examination of the circumstances served only to

  make the case more complex. In the first place, no reason

  could be given why the young man should have fastened the

  door upon the inside. There was the possibility that the

  murderer had done this and had afterwards escaped by the

  window. The drop was at least twenty feet, however, and a

  bed of crocuses in full bloom lay beneath. Neither the

  flowers nor the earth showed any sign of having been

  disturbed, nor were there any marks upon the narrow strip

  of grass which separated the house from the road.

  Apparently, therefore, it was the young man himself who had

  fastened the door. But how did he come by his death? No

  one could have climbed up to the window without leaving

  traces. Suppose a man had fired through the window, it

  would indeed be a remarkable shot who could with a revolver

  inflict so deadly a wound. Again, Park Lane is a

  frequented thoroughfare, and there is a cab-stand within

  a hundred yards of the house. No one had heard a shot.

  And yet there was the dead man, and there the revolver bullet,

  which had mushroomed out, as soft-nosed bullets will, and

  so inflicted a wound which must have caused instantaneous

  death. Such were the circumstances of the Park Lane

  Mystery, which were further complicated by entire absence

  of motive, since, as I have said, young Adair was not known

  to have any enemy, and no attempt had been made to remove

  the money or valuables in the room.

  All day I turned these facts over in my mind, endeavouring

  to hit upon some theory which could reconcile them all, and

  to find that line of least resistance which my poor friend

  had declared to be the starting-point of every investigation.

  I confess that I made little progress. In the evening I

  strolled across the Park, and found myself about six o'clock

  at the Oxford Street end of Park Lane. A group of loafers

  upon the pavements, all staring up at a particular window,

  directed me to the house which I had come to see. A tall,

  thin man with coloured glasses, whom I strongly suspected

  of being a plain-clothes detective, was pointing out some

  theory of his own, while the others crowded round to listen

  to what he said. I got as near him as I could, but his

  observations seemed to me to be absurd, so I withdrew again

  in some disgust. As I did so I struck against an elderly

  deformed man, who had been behind me, and I knocked down

  several books which he was carrying. I remember that as I

  picked them up I observed the title of one of them,

  "The Origin of Tree Worship," and it struck me that the

  fellow must be some poor bibliophile who, either as a trade

  or as a hobby, was a collector of obscure volumes.

  I endeavoured to apologize for the accident, but it was

  evident that these books which I had so unfortunately

  maltreated were very precious objects in the eyes of their

  owner. With a snarl of contempt he turned upon his heel,

  and I saw his curved back and white side-whiskers disappear

  among the throng.

  My observations of No. 427, Park Lane, did little to clear

  up the problem in which I was interested. The house was

  separated from the street by a low wall and railing, the

  whole not more than five feet high. It was perfectly easy,

  therefore, for anyone to get into the garden, but the

  window was entirely inaccessible, since there was no

  water-pipe or anything which could help the most active man

  to climb it. More puzzled than ever I retraced my steps to

  Kensington. I had not been in my study five minutes when

  the maid entered to say that a person desired to see me.

  To my astonishment it was none other than my strange old

  book-collector, his sharp, wizened face peering out from a

  frame of white hair, and his precious volumes, a dozen of

  them at least, wedged under his right arm.

  "You're surprised to see me, sir," said he, in a strange,

  croaking voice.

  I acknowledged that I was.

  "Well, I've a conscience, sir, and when I chanced to see

  you go into this house, as I came hobbling after you,

  I thought to myself, I'll just step in and see that kind

  gentleman, and tell him that if I was a bit gruff in my

  manner there was not any harm meant, and that I am much

  obliged to him for picking up my books."

  "You make too much of a trifle," said I. "May I ask how

  you knew who I was?"

  "Well, sir, if it isn't too great a liberty, I am a

  neighbour of yours, for you'll find my little bookshop at

  the corner of Church Street, and very happy to see you,

  I am sure. Maybe you collect yourself, sir; here's 'British

  Birds,' and 'Catullus,' and 'The Holy War' -- a bargain

  every one of them. With five volumes you could just fill

  that gap on that second shelf. It looks untidy, does it

  not, sir?"

  I moved my head to look at the cabinet behind me. When I

  turned again Sherlock Holmes was standing smiling at me

  across my study table. I rose to my feet, stared at him

  for some seconds in utter amazement, and then it appears

  that I must have fainted for the first and the last time

  in my life. Certainly a grey mist swirled before my eyes,

  and when it cleared I found my collar-ends undone and the

  tingling after-taste of brandy upon my lips. Holmes was

  bending over my chair, his flask in his hand.

  "My dear Watson," said the well-remembered voice, "I owe

  you a thousand apologies. I had no idea that you would be

  so affected."

  I gripped him by the arm.

  "Holmes!" I cried. "Is it really you? Can it indeed be

  that you are alive? Is it possible that you succeeded in

  climbing out of that awful abyss?"

  "Wait a moment," said he. "Are you sure that you are

  really fit to discuss things? I have given you a serious

  shock by my unnecessarily dramatic reappearance."

  "I am all right, but indeed, Holmes, I can hardly believe

  my eyes. Good heavens, to think that you -- you of all men

  -- should be standing in my study!" Again I gripped him

  by the sleeve and felt the thin, sinewy arm beneath it.

  "Well, you're not a spirit, anyhow," said I. "My dear chap,

  I am overjoyed to see you. Sit down and tell me how you came

  alive out of that dreadful chasm."

  He sat opposite to me and lit a cigarette in his old

  nonchalant manner. He wa
s dressed in the seedy frock-coat

  of the book merchant, but the rest of that individual lay

  in a pile of white hair and old books upon the table.

  Holmes looked even thinner and keener than of old, but

  there was a dead-white tinge in his aquiline face which

  told me that his life recently had not been a healthy one.

  "I am glad to stretch myself, Watson," said he. "It is no

  joke when a tall man has to take a foot off his stature for

  several hours on end. Now, my dear fellow, in the matter

  of these explanations we have, if I may ask for your

  co-operation, a hard and dangerous night's work in front

  of us. Perhaps it would be better if I gave you an account

  of the whole situation when that work is finished."

  "I am full of curiosity. I should much prefer to hear

  now."

  "You'll come with me to-night?"

  "When you like and where you like."

  "This is indeed like the old days. We shall have time for

  a mouthful of dinner before we need go. Well, then, about

  that chasm. I had no serious difficulty in getting out of

  it, for the very simple reason that I never was in it."

  "You never were in it?"

  "No, Watson, I never was in it. My note to you was

  absolutely genuine. I had little doubt that I had come to

  the end of my career when I perceived the somewhat sinister

  figure of the late Professor Moriarty standing upon the

  narrow pathway which led to safety. I read an inexorable

  purpose in his grey eyes. I exchanged some remarks with

  him, therefore, and obtained his courteous permission to

  write the short note which you afterwards received. I left

  it with my cigarette-box and my stick and I walked along

  the pathway, Moriarty still at my heels. When I reached

  the end I stood at bay. He drew no weapon, but he rushed

  at me and threw his long arms around me. He knew that his

  own game was up, and was only anxious to revenge himself

  upon me. We tottered together upon the brink of the fall.

  I have some knowledge, however, of baritsu, or the Japanese

  system of wrestling, which has more than once been very

  useful to me. I slipped through his grip, and he with a

  horrible scream kicked madly for a few seconds and clawed

  the air with both his hands. But for all his efforts he

  could not get his balance, and over he went. With my face

  over the brink I saw him fall for a long way. Then he

  struck a rock, bounded off, and splashed into the water."

  I listened with amazement to this explanation, which Holmes

  delivered between the puffs of his cigarette.

  "But the tracks!" I cried. "I saw with my own eyes that

  two went down the path and none returned."

  "It came about in this way. The instant that the Professor

  had disappeared it struck me what a really extraordinarily

  lucky chance Fate had placed in my way. I knew that

  Moriarty was not the only man who had sworn my death.

  There were at least three others whose desire for vengeance

  upon me would only be increased by the death of their

  leader. They were all most dangerous men. One or other

  would certainly get me. On the other hand, if all the

  world was convinced that I was dead they would take

  liberties, these men, they would lay themselves open, and

  sooner or later I could destroy them. Then it would be

  time for me to announce that I was still in the land of the

  living. So rapidly does the brain act that I believe I had

  thought this all out before Professor Moriarty had reached

  the bottom of the Reichenbach Fall.

  "I stood up and examined the rocky wall behind me. In your

  picturesque account of the matter, which I read with great

  interest some months later, you assert that the wall was

  sheer. This was not literally true. A few small footholds

  presented themselves, and there was some indication of a

  ledge. The cliff is so high that to climb it all was an

  obvious impossibility, and it was equally impossible to

  make my way along the wet path without leaving some tracks.

  I might, it is true, have reversed my boots, as I have done

  on similar occasions, but the sight of three sets of tracks

  in one direction would certainly have suggested a

  deception. On the whole, then, it was best that I should

  risk the climb. It was not a pleasant business, Watson.

  The fall roared beneath me. I am not a fanciful person,

  but I give you my word that I seemed to hear Moriarty's

  voice screaming at me out of the abyss. A mistake would

  have been fatal. More than once, as tufts of grass came

  out in my hand or my foot slipped in the wet notches of the

  rock, I thought that I was gone. But I struggled upwards,

  and at last I reached a ledge several feet deep and covered

  with soft green moss, where I could lie unseen in the most

  perfect comfort. There I was stretched when you, my dear

  Watson, and all your following were investigating in the

  most sympathetic and inefficient manner the circumstances

  of my death.

  "At last, when you had all formed your inevitable and

  totally erroneous conclusions, you departed for the hotel

  and I was left alone. I had imagined that I had reached

  the end of my adventures, but a very unexpected occurrence

  showed me that there were surprises still in store for me.

  A huge rock, falling from above, boomed past me, struck the

  path, and bounded over into the chasm. For an instant I

  thought that it was an accident; but a moment later,

  looking up, I saw a man's head against the darkening sky,

  and another stone struck the very ledge upon which I was

  stretched, within a foot of my head. Of course, the

  meaning of this was obvious. Moriarty had not been alone.

  A confederate -- and even that one glance had told me how

  dangerous a man that confederate was -- had kept guard

  while the Professor had attacked me. From a distance,

  unseen by me, he had been a witness of his friend's death

  and of my escape. He had waited, and then, making his

  way round to the top of the cliff, he had endeavoured to

  succeed where his comrade had failed.

  "I did not take long to think about it, Watson. Again I

  saw that grim face look over the cliff, and I knew that it

  was the precursor of another stone. I scrambled down on

  to the path. I don't think I could have done it in cold

  blood. It was a hundred times more difficult than getting

  up. But I had no time to think of the danger, for another

  stone sang past me as I hung by my hands from the edge of

  the ledge. Halfway down I slipped, but by the blessing of

  God I landed, torn and bleeding, upon the path. I took to

  my heels, did ten miles over the mountains in the darkness,

  and a week later I found myself in Florence with the

  certainty that no one in the world knew what had become of

  me.

  "I had only one confidant -- my brother Myc
roft. I owe you

  many apologies, my dear Watson, but it was all-important

  that it should be thought I was dead, and it is quite

  certain that you would not have written so convincing an

  account of my unhappy end had you not yourself thought that

  it was true. Several times during the last three years I

  have taken up my pen to write to you, but always I feared

  lest your affectionate regard for me should tempt you to

  some indiscretion which would betray my secret. For that

  reason I turned away from you this evening when you upset

  my books, for I was in danger at the time, and any show of

  surprise and emotion upon your part might have drawn

  attention to my identity and led to the most deplorable and

  irreparable results. As to Mycroft, I had to confide in

  him in order to obtain the money which I needed. The

  course of events in London did not run so well as I had

  hoped, for the trial of the Moriarty gang left two of its

  most dangerous members, my own most vindictive enemies, at

  liberty. I travelled for two years in Tibet, therefore,

  and amused myself by visiting Lhassa and spending some days

  with the head Llama. You may have read of the remarkable

  explorations of a Norwegian named Sigerson, but I am sure

  that it never occurred to you that you were receiving news

  of your friend. I then passed through Persia, looked in at

  Mecca, and paid a short but interesting visit to the

  Khalifa at Khartoum, the results of which I have

  communicated to the Foreign Office. Returning to France

  I spent some months in a research into the coal-tar

  derivatives, which I conducted in a laboratory at

  Montpelier, in the South of France. Having concluded this

  to my satisfaction, and learning that only one of my

  enemies was now left in London, I was about to return

  when my movements were hastened by the news of this very

  remarkable Park Lane Mystery, which not only appealed to

  me by its own merits, but which seemed to offer some most

  peculiar personal opportunities. I came over at once to

  London, called in my own person at Baker Street, threw Mrs.

  Hudson into violent hysterics, and found that Mycroft had

  preserved my rooms and my papers exactly as they had always

  been. So it was, my dear Watson, that at two o'clock

  to-day I found myself in my old arm-chair in my own old

  room, and only wishing that I could have seen my old friend

  Watson in the other chair which he has so often adorned."

  Such was the remarkable narrative to which I listened on

  that April evening -- a narrative which would have been

  utterly incredible to me had it not been confirmed by the

  actual sight of the tall, spare figure and the keen, eager

  face, which I had never thought to see again. In some

  manner he had learned of my own sad bereavement, and his

  sympathy was shown in his manner rather than in his words.

  "Work is the best antidote to sorrow, my dear Watson," said

  he, "and I have a piece of work for us both to-night which,

  if we can bring it to a successful conclusion, will in

  itself justify a man's life on this planet." In vain I

  begged him to tell me more. "You will hear and see enough

  before morning," he answered. "We have three years of the

  past to discuss. Let that suffice until half-past nine,

  when we start upon the notable adventure of the empty house."

  It was indeed like old times when, at that hour, I found

  myself seated beside him in a hansom, my revolver in my

  pocket and the thrill of adventure in my heart. Holmes was

  cold and stern and silent. As the gleam of the

  street-lamps flashed upon his austere features I saw that

  his brows were drawn down in thought and his thin lips

  compressed. I knew not what wild beast we were about to

  hunt down in the dark jungle of criminal London, but I was

  well assured from the bearing of this master huntsman that

  the adventure was a most grave one, while the sardonic

  smile which occasionally broke through his ascetic gloom

  boded little good for the object of our quest.

  I had imagined that we were bound for Baker Street, but

  Holmes stopped the cab at the corner of Cavendish Square.
