“I see what you mean.” This point, I think, impressed Markham more strongly than any other Vance had raised; for the presence of the poker on the dressing-table had not been explained away either by Heath or Inspector Brenner. . . . “Is that the reason you questioned Skeel as if he might have been present when your other visitor was there?”

“Exactly. By the evidence of the jewel-case I knew he either was in the apartment when the bogus crime of robbery was being staged, or else had come upon the scene when it was over and the stage-director had cleared out. . . . From his reactions to my questions I rather fancy he was present.”

“Hiding in the closet?”

How else could that one clothes-press have escaped the rifling activities of the pseudo-burglar? He wouldn’t have omitted it deliberately, and he was far too thorough-going to have overlooked it accidentally.—Then there are the finger-prints on the knob. . . .”

CHAPTER XV.
Four Possibilities

(Wednesday, September 12; evening)

When Vance finished speaking, there was a long silence. Markham, impressed by the other’s earnestness, sat in a brown study. His ideas had been shaken. The theory of Skeel’s guilt, to which he had clung from the moment of the identification of the finger-prints, had, it must be admitted, not entirely satisfied him, although he had been able to suggest no alternative. Now Vance had categorically repudiated this theory and at the same time had advanced another which, despite its indefiniteness, had nevertheless taken into account all the physical points of the case; and Markham, at first antagonistic, had found himself, almost against his will, becoming more and more sympathetic to this new point of view.

“Damn it, Vance!” he said. “I’m not in the least convinced by your theatrical theory. And yet, I feel a curious undercurrent of plausibility in your analyses. . . . I wonder——”
