Markham introduced him to Vance and me, and briefly explained that we were working with him on the case, and that he had thought it best to take us fully into his confidence.

Spotswoode gave him a dubious look, but immediately bowed his acceptance of the decision.

“I’m in your hands, Mr. Markham,” he replied, in a well-bred but somewhat high-pitched voice, “and I concur, of course, with whatever you think advisable.” He turned to Vance with an apologetic smile. “I’m in a rather unpleasant position, and naturally feel a little sensitive about it.”

“I’m something of an antinomian,” Vance pleasantly informed him. “At any rate, I’m not a moralist; so my attitude in the matter is quite academic.”

Spotswoode laughed softly.

“I wish my family held a similar point of view; but I’m afraid they would not be so tolerant of my foibles.”

“It’s only fair to tell you, Mr. Spotswoode,” interposed Markham, “that there is a bare possibility I may have to call you as a witness.”

The man looked up quickly, his face clouding over, but he made no comment.

“The fact is,” continued Markham, “we are about to make an arrest, and your testimony may be needed to establish the time of Miss Odell’s return to her apartment, and also to substantiate the fact that there was presumably some one in her rooms after you had left. Her screams and calls for help, which you heard, may prove vital evidence in obtaining a conviction.”

Spotswoode seemed rather appalled at the thought of his relations with the girl becoming public, and for several minutes he sat with averted eyes.
