happened in the last three days, and that is that nothing has

  happened. I get reports almost hourly from the Government, and it

  is certain that nowhere in Europe is there any sign of trouble.

  Now, if this letter were loose -- no, it _can't_ be loose -- but

  if it isn't loose, where can it be? Who has it? Why is it held

  back? That's the question that beats in my brain like a hammer.

  Was it, indeed, a coincidence that Lucas should meet his death on

  the night when the letter disappeared? Did the letter ever reach

  him? If so, why is it not among his papers? Did this mad wife of

  his carry it off with her? If so, is it in her house in Paris?

  How could I search for it without the French police having their

  suspicions aroused? It is a case, my dear Watson, where the law

  is as dangerous to us as the criminals are. Every man's hand is

  against us, and yet the interests at stake are colossal. Should I

  bring it to a successful conclusion it will certainly represent

  the crowning glory of my career. Ah, here is my latest from the

  front!" He glanced hurriedly at the note which had been handed

  in. "Halloa! Lestrade seems to have observed something of

  interest. Put on your hat, Watson, and we will stroll down

  together to Westminster."

  It was my first visit to the scene of the crime -- a high, dingy,

  narrow-chested house, prim, formal, and solid, like the century

  which gave it birth. Lestrade's bulldog features gazed out at us

  from the front window, and he greeted us warmly when a big

  constable had opened the door and let us in. The room into which

  we were shown was that in which the crime had been committed, but

  no trace of it now remained, save an ugly, irregular stain upon

  the carpet. This carpet was a small square drugget in the centre

  of the room, surrounded by a broad expanse of beautiful,

  old-fashioned wood-flooring in square blocks highly polished.

  Over the fireplace was a magnificent trophy of weapons, one of

  which had been used on that tragic night. In the window was a

  sumptuous writing-desk, and every detail of the apartment, the

  pictures, the rugs, and the hangings, all pointed to a taste which

  was luxurious to the verge of effeminacy.

  "Seen the Paris news?" asked Lestrade.

  Holmes nodded.

  "Our French friends seem to have touched the spot this time. No

  doubt it's just as they say. She knocked at the door -- surprise

  visit, I guess, for he kept his life in water-tight compartments.

  He let her in -- couldn't keep her in the street. She told him

  how she had traced him, reproached him, one thing led to another,

  and then with that dagger so handy the end soon came. It wasn't

  all done in an instant, though, for these chairs were all swept

  over yonder, and he had one in his hand as if he had tried to hold

  her off with it. We've got it all clear as if we had seen it."

  Holmes raised his eyebrows.

  "And yet you have sent for me?"

  "Ah, yes, that's another matter -- a mere trifle, but the sort of

  thing you take an interest in -- queer, you know, and what you

  might call freakish. It has nothing to do with the main fact --

  can't have, on the face of it."

  "What is it, then?"

  "Well, you know, after a crime of this sort we are very careful to

  keep things in their position. Nothing has been moved. Officer

  in charge here day and night. This morning, as the man was buried

  and the investigation over -- so far as this room is concerned --

  we thought we could tidy up a bit. This carpet. You see, it is

  not fastened down; only just laid there. We had occasion to raise

  it. We found ----"

  "Yes? You found ----"

  Holmes's face grew tense with anxiety.

  "Well, I'm sure you would never guess in a hundred years what we

  did find. You see that stain on the carpet? Well, a great deal

  must have soaked through, must it not?"

  "Undoubtedly it must."

  "Well, you will be surprised to hear that there is no stain on the

  white woodwork to correspond."

  "No stain! But there must ----"

  "Yes; so you would say. But the fact remains that there isn't."

  He took the corner of the carpet in his hand and, turning it over,

  he showed that it was indeed as he said.

  "But the underside is as stained as the upper. It must have left

  a mark."

  Lestrade chuckled with delight at having puzzled the famous

  expert.

  "Now I'll show you the explanation. There _is_ a second stain,

  but it does not correspond with the other. See for yourself." As

  he spoke he turned over another portion of the carpet, and there,

  sure enough, was a great crimson spill upon the square white

  facing of the old-fashioned floor. "What do you make of that, Mr.

  Holmes?"

  "Why, it is simple enough. The two stains did correspond, but the

  carpet has been turned round. As it was square and unfastened it

  was easily done."

  The official police don't need you, Mr. Holmes, to tell them that

  the carpet must have been turned round. That's clear enough, for

  the stains lie above each other -- if you lay it over this way.

  But what I want to know is, who shifted the carpet, and why?"

  I could see from Holmes's rigid face that he was vibrating with

  inward excitement.

  "Look here, Lestrade," said he, "has that constable in the passage

  been in charge of the place all the time?"

  "Yes, he has."

  "Well, take my advice. Examine him carefully. Don't do it before

  us. We'll wait here. You take him into the back room. You'll be

  more likely to get a confession out of him alone. Ask him how he

  dared to admit people and leave them alone in this room. Don't

  ask him if he has done it. Take it for granted. Tell him you

  _know_ someone has been here. Press him. Tell him that a full

  confession is his only chance of forgiveness. Do exactly what I

  tell you!"

  "By George, if he knows I'll have it out of him!" cried Lestrade.

  He darted into the hall, and a few moments later his bullying

  voice sounded from the back room.

  "Now, Watson, now!" cried Holmes, with frenzied eagerness. All

  the demoniacal force of the man masked behind that listless manner

  burst out in a paroxysm of energy. He tore the drugget from the

  floor, and in an instant was down on his hands and knees clawing

  at each of the squares of wood beneath it. One turned sideways as

  he dug his nails into the edge of it. It hinged back like the lid

  of a box. A small black cavity opened beneath it. Holmes plunged

  his eager hand into it, and drew it out with a bitter snarl of

  anger and disappointment. It was empty.

  "Quick, Watson, quick! Get it back again!" The wooden lid was

  replaced, and the drugget had only just been drawn straight when

  Lestrade's voice was heard in the passage. He found Holmes

  leaning languidly against the mantelpiece, resigned and patient,

  endeavouri
ng to conceal his irrepressible yawns.

  "Sorry to keep you waiting, Mr. Holmes. I can see that you are

  bored to death with the whole affair. Well, he has confessed, all

  right. Come in here, MacPherson. Let these gentlemen hear of

  your most inexcusable conduct."

  The big constable, very hot and penitent, sidled into the room.

  "I meant no harm, sir, I'm sure. The young woman came to the door

  last evening -- mistook the house, she did. And then we got

  talking. It's lonesome, when you're on duty here all day."

  "Well, what happened then?"

  "She wanted to see where the crime was done -- had read about it

  in the papers, she said. She was a very respectable, well-spoken

  young woman, sir, and I saw no harm in letting her have a peep.

  When she saw that mark on the carpet, down she dropped on the

  floor, and lay as if she were dead. I ran to the back and got

  some water, but I could not bring her to. Then I went round the

  corner to the Ivy Plant for some brandy, and by the time I had

  brought it back the young woman had recovered and was off --

  ashamed of herself, I dare say, and dared not face me."

  "How about moving that drugget?"

  "Well, sir, it was a bit rumpled, certainly, when I came back. You

  see, she fell on it, and it lies on a polished floor with nothing

  to keep it in place. I straightened it out afterwards."

  "It's a lesson to you that you can't deceive me, Constable

  MacPherson," said Lestrade, with dignity. "No doubt you thought

  that your breach of duty could never be discovered, and yet a mere

  glance at that drugget was enough to convince me that someone had

  been admitted to the room. It's lucky for you, my man, that

  nothing is missing, or you would find yourself in Queer Street.

  I'm sorry to have called you down over such a petty business, Mr.

  Holmes, but I thought the point of the second stain not

  corresponding with the first would interest you."

  "Certainly, it was most interesting. Has this woman only been

  here once, constable?"

  "Yes, sir, only once."

  "Who was she?"

  "Don't know the name, sir. Was answering an advertisement about

  type-writing, and came to the wrong number -- very pleasant,

  genteel young woman, sir."

  "Tall? Handsome?"

  "Yes, sir; she was a well-grown young woman. I suppose you might

  say she was handsome. Perhaps some would say she was very

  handsome. 'Oh, officer, do let me have a peep!' says she. She

  had pretty, coaxing ways, as you might say, and I thought there

  was no harm in letting her just put her head through the door."

  "How was she dressed?"

  "Quiet, sir -- a long mantle down to her feet."

  "What time was it?"

  "It was just growing dusk at the time. They were lighting the

  lamps as I came back with the brandy."

  "Very good," said Holmes. "Come, Watson, I think that we have

  more important work elsewhere."

  As we left the house Lestrade remained in the front room, while

  the repentant constable opened the door to let us out. Holmes

  turned on the step and held up something in his hand. The

  constable stared intently.

  "Good Lord, sir!" he cried, with amazement on his face. Holmes

  put his finger on his lips, replaced his hand in his

  breast-pocket, and burst out laughing as we turned down the

  street. "Excellent!" said he. "Come, friend Watson, the curtain

  rings up for the last act. You will be relieved to hear that

  there will be no war, that the Right Honourable Trelawney Hope

  will suffer no set-back in his brilliant career, that the

  indiscreet Sovereign will receive no punishment for his

  indiscretion, that the Prime Minister will have no European

  complication to deal with, and that with a little tact and

  management upon our part nobody will be a penny the worse for what

  might have been a very ugly incident."

  My mind filled with admiration for this extraordinary man.

  "You have solved it!" I cried.

  "Hardly that, Watson. There are some points which are as dark as

  ever. But we have so much that it will be our own fault if we

  cannot get the rest. We will go straight to Whitehall Terrace and

  bring the matter to a head."

  When we arrived at the residence of the European Secretary it was

  for Lady Hilda Trelawney Hope that Sherlock Holmes inquired. We

  were shown into the morning-room.

  "Mr. Holmes!" said the lady, and her face was pink with her

  indignation, "this is surely most unfair and ungenerous upon your

  part. I desired, as I have explained, to keep my visit to you a

  secret, lest my husband should think that I was intruding into his

  affairs. And yet you compromise me by coming here and so showing

  that there are business relations between us."

  "Unfortunately, madam, I had no possible alternative. I have been

  commissioned to recover this immensely important paper. I must

  therefore ask you, madam, to be kind enough to place it in my

  hands."

  The lady sprang to her feet, with the colour all dashed in an

  instant from her beautiful face. Her eyes glazed -- she tottered

  -- I thought that she would faint. Then with a grand effort she

  rallied from the shock, and a supreme astonishment and indignation

  chased every other expression from her features.

  "You -- you insult me, Mr. Holmes."

  "Come, come, madam, it is useless. Give up the letter."

  She darted to the bell.

  "The butler shall show you out."

  "Do not ring, Lady Hilda. If you do, then all my earnest efforts

  to avoid a scandal will be frustrated. Give up the letter and all

  will be set right. If you will work with me I can arrange

  everything. If you work against me I must expose you."

  She stood grandly defiant, a queenly figure, her eyes fixed upon

  his as if she would read his very soul. Her hand was on the bell,

  but she had forborne to ring it.

  "You are trying to frighten me. It is not a very manly thing, Mr.

  Holmes, to come here and browbeat a woman. You say that you know

  something. What is it that you know?"

  "Pray sit down, madam. You will hurt yourself there if you fall.

  I will not speak until you sit down. Thank you."

  "I give you five minutes, Mr. Holmes."

  "One is enough, Lady Hilda. I know of your visit to Eduardo

  Lucas, of your giving him this document, of your ingenious return

  to the room last night, and of the manner in which you took the

  letter from the hiding-place under the carpet."

  She stared at him with an ashen face and gulped twice before she

  could speak.

  "You are mad, Mr. Holmes -- you are mad!" she cried, at last.

  He drew a small piece of cardboard from his pocket. It was the

  face of a woman cut out of a portrait.

  "I have carried this because I thought it might be useful," said

  he. "The policeman has recognised it."

  She gave a gasp and her head dropped back in the chair.

  "Come, Lady Hilda.
You have the letter. The matter may still be

  adjusted. I have no desire to bring trouble to you. My duty ends

  when I have returned the lost letter to your husband. Take my

  advice and be frank with me; it is your only chance."

  Her courage was admirable. Even now she would not own defeat.

  "I tell you again, Mr. Holmes, that you are under some absurd

  illusion."

  Holmes rose from his chair.

  "I am sorry for you, Lady Hilda. I have done my best for you; I

  can see that it is all in vain."

  He rang the bell. The butler entered.

  "Is Mr. Trelawney Hope at home?"

  "He will be home, sir, at a quarter to one."

  Holmes glanced at his watch.

  "Still a quarter of an hour," said he. "Very good, I shall wait."

  The butler had hardly closed the door behind him when Lady Hilda

  was down on her knees at Holmes's feet, her hands outstretched,

  her beautiful face upturned and wet with her tears.

  "Oh, spare me, Mr. Holmes! Spare me!" she pleaded, in a frenzy of

  supplication. "For Heaven's sake, don't tell him! I love him so!

  I would not bring one shadow on his life, and this I know would

  break his noble heart."

  Holmes raised the lady. "I am thankful, madam, that you have come

  to your senses even at this last moment! There is not an instant

  to lose. Where is the letter?"

  She darted across to a writing-desk, unlocked it, and drew out a

  long blue envelope.

  "Here it is, Mr. Holmes. Would to Heaven I had never seen it!"

  "How can we return it?" Holmes muttered. "Quick, quick, we must

  think of some way! Where is the despatch-box?"

  "Still in his bedroom."

  "What a stroke of luck! Quick, madam, bring it here!"

  A moment later she had appeared with a red flat box in her hand.

  "How did you open it before? You have a duplicate key? Yes, of

  course you have. Open it!"

  From out of her bosom Lady Hilda had drawn a small key. The box

  flew open. It was stuffed with papers. Holmes thrust the blue

  envelope deep down into the heart of them, between the leaves of

  some other document. The box was shut, locked, and returned to

  the bedroom.

  "Now we are ready for him," said Holmes; "we have still ten

  minutes. I am going far to screen you, Lady Hilda. In return you

  will spend the time in telling me frankly the real meaning of this

  extraordinary affair."

  "Mr. Holmes, I will tell you everything," cried the lady. "Oh,

  Mr. Holmes, I would cut off my right hand before I gave him a

  moment of sorrow! There is no woman in all London who loves her

  husband as I do, and yet if he knew how I have acted -- how I have

  been compelled to act -- he would never forgive me. For his own

  honour stands so high that he could not forget or pardon a lapse

  in another. Help me, Mr. Holmes! My happiness, his happiness,

  our very lives are at stake!"

  "Quick, madam, the time grows short!"

  "It was a letter of mine, Mr. Holmes, an indiscreet letter written

  before my marriage -- a foolish letter, a letter of an impulsive,

  loving girl. I meant no harm, and yet he would have thought it

  criminal. Had he read that letter his confidence would have been

  for ever destroyed. It is years since I wrote it. I had thought

  that the whole matter was forgotten. Then at last I heard from

  this man, Lucas, that it had passed into his hands, and that he

  would lay it before my husband. I implored his mercy. He said

  that he would return my letter if I would bring him a certain

  document which he described in my husband's despatch-box. He had

  some spy in the office who had told him of its existence. He

  assured me that no harm could come to my husband. Put yourself in
