“This: that one of the blood spots marking the criminal’s steps through the room was decidedly more pronounced than the rest; and, what was even more important, that the window out of which I was looking had its counterpart in the house on the opposite side of the alley. In gazing through the one I was gazing through the other; and not only that, but into the darkened area of the room beyond. Instantly I saw how the latter fact might be made to explain the former one. But before I say how, let me ask if it is quite settled among you that the smears on the floor and stairs mark the passage of the criminal’s footsteps!”
“Certainly; and very bloody feet they must have been too. His shoes—or rather his one shoe—for the proof is plain that only the right one left its mark—must have become thoroughly saturated to carry its traces so far.”
“Do you think that any amount of saturation would have done this? Or, if you are not ready to agree to that, that a shoe so covered with blood could have failed to leave behind it some hint of its shape, some imprint, however faint, of heel or toe? But nowhere did it do this. We see a smear—and that is all.”
“You are right, Miss Strange; you are always right. And what do you gather from this?”
She looked to see how much he expected from her, and, meeting an eye not quite as free from ironic suggestion as his words had led her to expect, faltered a little as she proceeded to say:
“My opinion is a girl’s opinion, but such as it is you have the right to have it. From the indications mentioned I could draw but this conclusion: that the blood which accompanied the criminal’s footsteps was not carried through the house by his shoes;—he wore no shoes; he did not even wear stockings; probably he had none. For reasons which appealed to his judgment, he went about his wicked work barefoot; and it was the blood from his own veins and not from those of his victim which made the trail we have followed with so much interest. Do you forget those broken beads;—how he kicked them about and stamped upon them in his fury? One of them pierced the ball of his foot, and that so sharply that it not only spurted blood but kept on bleeding with every step he took. Otherwise, the trail would have been lost after his passage up the stairs.”
“Fine!” There was no irony in the bureau-chief’s eye now. “You are progressing, Miss Strange. Allow me, I pray, to kiss your hand. It is a liberty I have never taken, but one which would greatly relieve my present stress of feeling.”
She lifted her hand toward him, but it was in gesture, not in recognition of his homage.
“Thank you,” said she, “but I claim no monopoly on deductions so simple as these. I have not the least doubt that not only yourself but every member of the force has made the same. But there is a little matter which may have escaped the police, may even have escaped you. To that I would now call your attention since through it I have been enabled, after a little necessary groping, to reach the open. You remember the one large blotch on the upper floor where the man dropped the wallet? That blotch, more or less commingled with a fainter one, possessed great significance for me from the first moment I saw it. How came his foot to bleed so much more profusely at that one spot than at any other? There could be but one answer: because here a surprise met him—a surprise so startling to him in his present state of mind, that he gave a quick spring backward, with the result that his wounded foot came down suddenly and forcibly instead of easily as in his previous wary tread. And what was the surprise? I made it my business to find out, and now I can tell you that it was the sight of a woman’s face staring upon him from the neighbouring house which he had probably been told was empty. The shock disturbed his judgment. He saw his crime discovered—his guilty secret read, and fled in unreasoning panic. He might better have held on to his wits. It was this display of fear which led me to search after its cause, and consequently to discover that at this especial hour more than one person had been in the Shaffer house; that, in fact, a marriage had been celebrated there under circumstances as romantic as any we read of in books, and that this marriage, privately carried out, had been followed by an immediate voyage of the happy couple on one of the White Star steamers. With the rest you are conversant. I do not need to say anything about what has followed the sending of that Marconi.”
“But I am going to say something about your work in this matter, Miss Strange. The big detectives about here will have to look sharp if—”
