"Well, as for that," he said, slowly, "I have reason to believe that I might have laid hands upon him, if I had been in this neighborhood last night between—h-m-m-m—between ten and twelve o'clock." If he expected this avowal of what he imagined the circumstances to be to make any impression upon the girl he was disappointed; for she was again the frozen image, not to be swayed by any influence under his control.

But not so the Doctor. He looked at the detective, with knitted brow, for a moment; then, after a hasty side-glance at his sister, "I see," he said; "I am merely a peg upon which to hang references to things of which I am entirely ignorant.
