once:
"According to the facts as you have stated them, the guilt must necessarily rest upon one or both of the other two persons. But this is assuming that it really was a murder, that there really was no mode of ingress, and that there really were no other persons in the apartment."
Having secured Fleming Stone's interest in the abstract statement, I proceeded to lay before him the concrete story of the Pembroke affair.
He listened gravely, asking only one or two questions, and when I had told him all I knew about it he sat thinking for a few moments.
At last, unable to control my impatience, I said: "Do you now think the guilt rests upon either one or both of those women?"
As I have said, Mr. Stone was not of the secretive and close-mouthed style of detective, and he said in his frank and pleasant way: "Not necessarily, by any means. Indeed, from what you have told me, I should say that the two women knew nothing about the crime until the morning. But this, of course, is a mere surmise, based on your account of the case."
As I had told him the facts as I knew them, with all their horrible incrimination of Janet, I was greatly relieved at his words.
"Then," said I, "will you take up the case, and find the criminal as soon as may be? Money is no object, but time is precious, as I strongly desire to avoid any possibility of a trial of Miss Pembroke."
"Have you any other clues other than those you have told me?"
"I haven't told you any," I said, in some surprise; "but we certainly have several."
He listened with the greatest attention, while I told him in rapid succession of the key, the time-table, the ticket stubs, the torn telegram, the handkerchief, and finally, the missing money.
"Have you traced these to their sources?" he inquired.
"We have, and each one led to a different man."
I then told him of Jonathan Scudder, of Graham Leroy, of James Decker, and of William Sydney Gresham, and he listened with a half-smile on his pleasant, responsive face.
"Of course you can see all these clues for yourself," I went on, "and I feel sure, Mr. Stone, that by an examination of them, you can deduce much of the personality of the criminal."
"I don't care to see them," was his astonishing answer; "I have already deduced from them the evidence that they clearly show."
"Your statement would amaze me," I said, "except that I had resolved not to be surprised at anything you might say or do, for I know your methods are mysterious and your powers little short of miraculous."
"Don't credit me with supernatural ability, Mr. Landon," said Stone, smiling genially. "Let me compliment you on the graphic way in which you have described that collection of clues. I can fairly see them, in my mind's eye lying before me. Were not the ticket stubs bent and broken and a good deal soiled?"
"They were," I said, staring at him.
"And was the time-table smudged with dirt, and perhaps bearing an impress of tiny dots in regular rows?"
"Now I know you're a wizard!" I exclaimed, "for that's exactly what I did see! such a mark on the first page of that time-table!"
"It might easily not have been there," said Stone, musingly; "I confess I chanced that. It was merely a hazard, but it helps. Yes, Mr. Landon, your collection of clues is indeed valuable and of decided assistance in discovering the identity of the person or persons unknown."
It struck a chill to my heart that Fleming Stone seemed to avoid the use of a masculine pronoun. Could he, too, think that a woman was implicated, and if not, why didn't he say the man who committed the crime, instead of dodging behind the vague term he had used. With a desperate idea of forcing this point, I said; "The Coroner believes that since the weapon used was a hat-pin, the criminal was a woman."
"Why did you say it was a hat-pin?" said Fleming Stone, and I realized that his brain was already busy with the subtleties of the case.
"The doctors stated that it was part of a hat-pin, the other end of which had been broken off."
"Did you see the pin that was extracted from the wound?"
"I did."
"How long was it?"
"Almost exactly four inches."
"And are you prepared to affirm that it is part of a hat-pin, and not a complete pin of a shorter length?"
"I am not. The thought did not before occur to me. But as it had no head on it, we assumed that it was probably the half of a broken hat-pin. It is by no means the first instance on record of using a hat-pin as a murderous weapon."
"No," said Fleming Stone; "and yet that does not prove it a hat-pin. May it not have been a shawl-pin, or some shorter pin that women use in their costumes?"
"It may have been," said I; "but women do not wear shawls nowadays. At any rate, any pin of that length would seem to indicate a woman's crime."
"Well, as a rule," said Fleming Stone, smiling, "we men do not pin our garments together; but I dare say almost any man, if he wanted one, could gain possession of such a pin."
How true this was, and how foolish we had been to assume that a woman's pin must have meant a woman's crime! A picture passed through my mind of Laura's dressing-table, where I could have procured any kind of a pin, with no trouble whatever.
"Moreover," went on Fleming Stone, "the great majority of hat-pins used in America will not break. They will bend, as they are usually made of iron, though occasionally of steel."
I looked at the man with growing admiration. How widespread was his knowledge, and how logical his deduction!
"I should have to see the pin," said Stone, "before drawing any conclusion from it. You did not examine it closely, you say?"
I had not said so, but I suppose he deduced it from my slight knowledge of its characteristics.
"I did not examine it through a microscope," I replied.
"You should have done so. If it were really a broken hat-pin, it would show a clean, bright break at the end; whereas, were it a shorter pin which had lost its head, it would show at the end a fraction of an inch of duller steel, and perhaps an irregular surface where the head had been attached."
"I can see that you are right, but I cannot see why it should make much difference which it was."
"My dear sir, according to your statement, the only clue we have to work upon is the weapon which was used. The weapon is always an important item, if not the most important, and it cannot be scrutinized too closely or examined too minutely, for, sooner or later, it is almost always certain to expose the criminal."
"I had thought," I said humbly, "that I possessed a degree of detective instinct, but I now see I was mistaken. I assumed the pin to be a hat-pin, and thought no more about it."
"It may be one," said Stone, "and the only way to find out is to see it. Of course I must also examine the apartment, and then, if necessary, question some of the parties concerned. But at this moment I have little doubt in my mind as to who killed Robert Pembroke. I will take the case, because, though unusual, it promises to be a short one. I think I may safely say that by to-morrow night at this hour we will not only have discovered the criminal, but obtained a confession. But I will say the criminal has been very, very clever. In fact, I think I should never have conceived of such various kinds of cleverness combined in one crime. But, as is often the case, he has outwitted himself. His very cleverness is his undoing."
Surely the man was a wizard! I looked at him without a word after he had made his astounding announcement. I had no idea whom he suspected, but I knew he would not tell me if I asked, so I thought best to express no curiosity, but to leave the matter in his hands, and await his further pleasure.
"You can go at once to see the apartment," I said; "but to look
