floor is reached.” Manning was a thoughtful-looking chap. Though we had never met before, I knew of him and I had an impression that he was a civil engineer or something like that. I felt drawn to him at once, for he had a pleasant, responsive manner and a nice, kindly way with him. In appearance, he was scholarly, rather than business-like.

But on leaving the Trust Company Building, we found the place at last. At least, we found a door which was in the position where we supposed the elevator shaft would require it, and we tried to open it. This we failed to do. “Looks bad,” said Talcott, shaking his head. “If Amos Gately is in there, it’s because he’s unable to get out—or—unconscious.” He couldn’t bring himself to speak the crueler word that was in both
