had turned a cat loose in an aviary, and I was so horrified

  at his brutal cruelty that I would have nothing more to do

  with him.' She rummaged in a bureau, and presently she

  produced a photograph of a woman, shamefully defaced and

  mutilated with a knife. 'That is my own photograph,' she

  said. 'He sent it to me in that state, with his curse,

  upon my wedding morning.'

  "'Well,' said I, 'at least he has forgiven you now, since

  he has left all his property to your son.'

  "'Neither my son nor I want anything from Jonas Oldacre,

  dead or alive,' she cried, with a proper spirit. 'There is

  a God in Heaven, Mr. Holmes, and that same God who has

  punished that wicked man will show in His own good time

  that my son's hands are guiltless of his blood.'

  "Well, I tried one or two leads, but could get at nothing

  which would help our hypothesis, and several points which

  would make against it. I gave it up at last and off I went

  to Norwood.

  "This place, Deep Dene House, is a big modern villa of

  staring brick, standing back in its own grounds, with a

  laurel-clumped lawn in front of it. To the right and some

  distance back from the road was the timber-yard which had

  been the scene of the fire. Here's a rough plan on a leaf

  of my note-book. This window on the left is the one which

  opens into Oldacre's room. You can look into it from the

  road, you see. That is about the only bit of consolation I

  have had to-day. Lestrade was not there, but his head

  constable did the honours. They had just made a great

  treasure-trove. They had spent the morning raking among

  the ashes of the burned wood-pile, and besides the charred

  organic remains they had secured several discoloured metal

  discs. I examined them with care, and there was no doubt

  that they were trouser buttons. I even distinguished that

  one of them was marked with the name of 'Hyams,' who was

  Oldacre's tailor. I then worked the lawn very carefully

  for signs and traces, but this drought has made everything

  as hard as iron. Nothing was to be seen save that some

  body or bundle had been dragged through a low privet hedge

  which is in a line with the wood-pile. All that, of

  course, fits in with the official theory. I crawled about

  the lawn with an August sun on my back, but I got up at

  the end of an hour no wiser than before.

  "Well, after this fiasco I went into the bedroom and

  examined that also. The blood-stains were very slight,

  mere smears and discolorations, but undoubtedly fresh.

  The stick had been removed, but there also the marks were

  slight. There is no doubt about the stick belonging to our

  client. He admits it. Footmarks of both men could be made

  out on the carpet, but none of any third person, which

  again is a trick for the other side. They were piling up

  their score all the time and we were at a standstill.

  "Only one little gleam of hope did I get -- and yet it

  amounted to nothing. I examined the contents of the safe,

  most of which had been taken out and left on the table.

  The papers had been made up into sealed envelopes, one or

  two of which had been opened by the police. They were not,

  so far as I could judge, of any great value, nor did the

  bank-book show that Mr. Oldacre was in such very affluent

  circumstances. But it seemed to me that all the papers

  were not there. There were allusions to some deeds --

  possibly the more valuable -- which I could not find.

  This, of course, if we could definitely prove it, would

  turn Lestrade's argument against himself, for who would

  steal a thing if he knew that he would shortly inherit it?

  "Finally, having drawn every other cover and picked up no

  scent, I tried my luck with the housekeeper. Mrs.

  Lexington is her name, a little, dark, silent person, with

  suspicious and sidelong eyes. She could tell us something

  if she would -- I am convinced of it. But she was as close

  as wax. Yes, she had let Mr. McFarlane in at half-past

  nine. She wished her hand had withered before she had done

  so. She had gone to bed at half-past ten. Her room was at

  the other end of the house, and she could hear nothing of

  what passed. Mr. McFarlane had left his hat, and to the

  best of her belief his stick, in the hall. She had been

  awakened by the alarm of fire. Her poor, dear master had

  certainly been murdered. Had he any enemies? Well, every

  man had enemies, but Mr. Oldacre kept himself very much to

  himself, and only met people in the way of business. She

  had seen the buttons, and was sure that they belonged to

  the clothes which he had worn last night. The wood-pile

  was very dry, for it had not rained for a month. It burned

  like tinder, and by the time she reached the spot nothing

  could be seen but flames. She and all the firemen smelled

  the burned flesh from inside it. She knew nothing of the

  papers, nor of Mr. Oldacre's private affairs.

  "So, my dear Watson, there's my report of a failure. And

  yet -- and yet ----" -- he clenched his thin hands in a

  paroxysm of conviction -- "I _know_ it's all wrong. I feel

  it in my bones. There is something that has not come out,

  and that housekeeper knows it. There was a sort of sulky

  defiance in her eyes, which only goes with guilty

  knowledge. However, there's no good talking any more about

  it, Watson; but unless some lucky chance comes our way I

  fear that the Norwood Disappearance Case will not figure in

  that chronicle of our successes which I foresee that a

  patient public will sooner or later have to endure."

  "Surely," said I, "the man's appearance would go far with

  any jury?"

  "That is a dangerous argument, my dear Watson.

  You remember that terrible murderer, Bert Stevens,

  who wanted us to get him off in '87? Was there ever a more

  mild-mannered, Sunday-school young man?"

  "It is true."

  "Unless we succeed in establishing an alternative theory

  this man is lost. You can hardly find a flaw in the case

  which can now be presented against him, and all further

  investigation has served to strengthen it. By the way,

  there is one curious little point about those papers which

  may serve us as the starting-point for an inquiry.

  On looking over the bank-book I found that the low state of

  the balance was principally due to large cheques which have

  been made out during the last year to Mr. Cornelius.

  I confess that I should be interested to know who this

  Mr. Cornelius may be with whom a retired builder has such very

  large transactions. Is it possible that he has had a hand

  in the affair? Cornelius might be a broker, but we have

  found no scrip to correspond with these large payments.

  Failing any other indication my researches must now take

  the direction of an inquiry at the bank for the gentle
man

  who has cashed these cheques. But I fear, my dear fellow,

  that our case will end ingloriously by Lestrade hanging our

  client, which will certainly be a triumph for Scotland Yard."

  I do not know how far Sherlock Holmes took any sleep that

  night, but when I came down to breakfast I found him pale

  and harassed, his bright eyes the brighter for the dark

  shadows round them. The carpet round his chair was

  littered with cigarette-ends and with the early editions of

  the morning papers. An open telegram lay upon the table.

  "What do you think of this, Watson?" he asked, tossing it

  across.

  It was from Norwood, and ran as follows:--

  "IMPORTANT FRESH EVIDENCE TO HAND. MCFARLANE'S GUILT DEFINITELY

  ESTABLISHED. ADVISE YOU TO ABANDON CASE. -- LESTRADE." {2}

  "This sounds serious," said I.

  "It is Lestrade's little cock-a-doodle of victory," Holmes

  answered, with a bitter smile. "And yet it may be

  premature to abandon the case. After all, important fresh

  evidence is a two-edged thing, and may possibly cut in a

  very different direction to that which Lestrade imagines.

  Take your breakfast, Watson, and we will go out together

  and see what we can do. I feel as if I shall need your

  company and your moral support to-day."

  My friend had no breakfast himself, for it was one of his

  peculiarities that in his more intense moments he would

  permit himself no food, and I have known him presume upon

  his iron strength until he has fainted from pure inanition.

  "At present I cannot spare energy and nerve force for

  digestion," he would say, in answer to my medical

  remonstrances. I was not surprised, therefore, when this

  morning he left his untouched meal behind him and started

  with me for Norwood. A crowd of morbid sightseers were

  still gathered round Deep Dene House, which was just such

  a suburban villa as I had pictured. Within the gates

  Lestrade met us, his face flushed with victory, his manner

  grossly triumphant.

  "Well, Mr. Holmes, have you proved us to be wrong yet?

  Have you found your tramp?" he cried.

  "I have formed no conclusion whatever," my companion

  answered.

  "But we formed ours yesterday, and now it proves to be

  correct; so you must acknowledge that we have been a little

  in front of you this time, Mr. Holmes."

  "You certainly have the air of something unusual having

  occurred," said Holmes.

  Lestrade laughed loudly.

  "You don't like being beaten any more than the rest of us

  do," said he. "A man can't expect always to have it his

  own way, can he, Dr. Watson? Step this way, if you please,

  gentlemen, and I think I can convince you once for all that

  it was John McFarlane who did this crime."

  He led us through the passage and out into a dark hall beyond.

  "This is where young McFarlane must have come out to get

  his hat after the crime was done," said he. "Now, look at

  this." With dramatic suddenness he struck a match and by

  its light exposed a stain of blood upon the whitewashed

  wall. As he held the match nearer I saw that it was more

  than a stain. It was the well-marked print of a thumb.

  "Look at that with your magnifying glass, Mr. Holmes."

  "Yes, I am doing so."

  "You are aware that no two thumb marks are alike?"

  "I have heard something of the kind."

  "Well, then, will you please compare that print with this

  wax impression of young McFarlane's right thumb, taken by

  my orders this morning?"

  As he held the waxen print close to the blood-stain it did

  not take a magnifying glass to see that the two were

  undoubtedly from the same thumb. It was evident to me that

  our unfortunate client was lost.

  "That is final," said Lestrade.

  "Yes, that is final," I involuntarily echoed.

  "It is final," said Holmes.

  Something in his tone caught my ear, and I turned to look

  at him. An extraordinary change had come over his face.

  It was writhing with inward merriment. His two eyes were

  shining like stars. It seemed to me that he was making

  desperate efforts to restrain a convulsive attack of laughter.

  "Dear me! Dear me!" he said at last. "Well, now, who

  would have thought it? And how deceptive appearances may

  be, to be sure! Such a nice young man to look at! It is

  a lesson to us not to trust our own judgment, is it not,

  Lestrade?"

  "Yes, some of us are a little too much inclined to be

  cocksure, Mr. Holmes," said Lestrade. The man's insolence

  was maddening, but we could not resent it.

  "What a providential thing that this young man should press

  his right thumb against the wall in taking his hat from the

  peg! Such a very natural action, too, if you come to think

  of it." Holmes was outwardly calm, but his whole body gave

  a wriggle of suppressed excitement as he spoke. "By the way,

  Lestrade, who made this remarkable discovery?"

  "It was the housekeeper, Mrs. Lexington, who drew the night

  constable's attention to it."

  "Where was the night constable?"

  "He remained on guard in the bedroom where the crime was

  committed, so as to see that nothing was touched."

  "But why didn't the police see this mark yesterday?"

  "Well, we had no particular reason to make a careful

  examination of the hall. Besides, it's not in a very

  prominent place, as you see."

  "No, no, of course not. I suppose there is no doubt that

  the mark was there yesterday?"

  Lestrade looked at Holmes as if he thought he was going out

  of his mind. I confess that I was myself surprised both at

  his hilarious manner and at his rather wild observation.

  "I don't know whether you think that McFarlane came out of

  gaol in the dead of the night in order to strengthen the

  evidence against himself," said Lestrade. "I leave it to any

  expert in the world whether that is not the mark of his thumb."

  "It is unquestionably the mark of his thumb."

  "There, that's enough," said Lestrade. "I am a practical

  man, Mr. Holmes, and when I have got my evidence I come to

  my conclusions. If you have anything to say you will find

  me writing my report in the sitting-room."

  Holmes had recovered his equanimity, though I still seemed

  to detect gleams of amusement in his expression.

  "Dear me, this is a very sad development, Watson, is it not?"

  said he. "And yet there are singular points about it which

  hold out some hopes for our client."

  "I am delighted to hear it," said I, heartily. "I was

  afraid it was all up with him."

  "I would hardly go so far as to say that, my dear Watson.

  The fact is that there is one really serious flaw in this

  evidence to which our friend attaches so much importance."

  "Indeed, Holmes! What is it?"

  "Only this: that I _know_ that that mark was not there when

  I exami
ned the hall yesterday. And now, Watson, let us

  have a little stroll round in the sunshine."

  With a confused brain, but with a heart into which some

  warmth of hope was returning, I accompanied my friend in a

  walk round the garden. Holmes took each face of the house

  in turn and examined it with great interest. He then led

  the way inside and went over the whole building from

  basement to attics. Most of the rooms were unfurnished,

  but none the less Holmes inspected them all minutely.

  Finally, on the top corridor, which ran outside three

  untenanted bedrooms, he again was seized with a spasm of

  merriment.

  "There are really some very unique features about this

  case, Watson," said he. "I think it is time now that we

  took our friend Lestrade into our confidence. He has had

  his little smile at our expense, and perhaps we may do as

  much by him if my reading of this problem proves to be

  correct. Yes, yes; I think I see how we should approach it."

  The Scotland Yard inspector was still writing in the

  parlour when Holmes interrupted him.

  "I understood that you were writing a report of this case,"

  said he.

  "So I am."

  "Don't you think it may be a little premature? I can't

  help thinking that your evidence is not complete."

  Lestrade knew my friend too well to disregard his words.

  He laid down his pen and looked curiously at him.

  "What do you mean, Mr. Holmes?"

  "Only that there is an important witness whom you have not

  seen."

  "Can you produce him?"

  "I think I can."

  "Then do so."

  "I will do my best. How many constables have you?"

  "There are three within call."

  "Excellent!" said Holmes. "May I ask if they are all

  large, able-bodied men with powerful voices?"

  "I have no doubt they are, though I fail to see what their

  voices have to do with it."

  "Perhaps I can help you to see that and one or two other

  things as well," said Holmes. "Kindly summon your men,

  and I will try."

  Five minutes later three policemen had assembled in the hall.

  "In the outhouse you will find a considerable quantity of

  straw," said Holmes. "I will ask you to carry in two

  bundles of it. I think it will be of the greatest

  assistance in producing the witness whom I require. Thank

  you very much. I believe you have some matches in your

  pocket, Watson. Now, Mr. Lestrade, I will ask you all to

  accompany me to the top landing."

  As I have said, there was a broad corridor there, which ran

  outside three empty bedrooms. At one end of the corridor

  we were all marshalled by Sherlock Holmes, the constables

  grinning and Lestrade staring at my friend with amazement,

  expectation, and derision chasing each other across his

  features. Holmes stood before us with the air of a

  conjurer who is performing a trick.

  "Would you kindly send one of your constables for two

  buckets of water? Put the straw on the floor here, free

  from the wall on either side. Now I think that we are all

  ready."

  Lestrade's face had begun to grow red and angry.

  "I don't know whether you are playing a game with us, Mr.

  Sherlock Holmes," said he. "If you know anything, you can

  surely say it without all this tomfoolery."

  "I assure you, my good Lestrade, that I have an excellent

  reason for everything that I do. You may possibly remember

  that you chaffed me a little some hours ago, when the sun

  seemed on your side of the hedge, so you must not grudge me

  a little pomp and ceremony now. Might I ask you, Watson,

  to open that window, and then to put a match to the edge of

  the straw?"

  I did so, and, driven by the draught, a coil of grey smoke

  swirled down the corridor, while the dry straw crackled and

  flamed.

  "Now we must see if we can find this witness for you,

  Lestrade. Might I ask you all to join in the cry of
