Markham rose, and began pacing meditatively. At length, halting in front of the operator, he asked another question:
"Did you hear any other suspicious sounds in this apartment after the man left?"
"Not a sound of any kind, sir," Jessup declared. "Some one from outside the building, however, telephoned Miss Odell about ten minutes later, and a man's voice answered from her apartment."
"What's this!" Markham spun round, and Heath sat up at attention, his eyes wide. "Tell me every detail of that call."
Jessup complied unemotionally.
"About twenty minutes to twelve a trunk-light flashed on the board, and when I answered it, a man asked for Miss Odell. I plugged the connection through, and after a short wait the receiver was lifted from her phone—you can tell when a receiver's taken off the hook, because the guide-light on the board goes out—and a man's voice answered 'Hello.' I pulled the listening-in key over, and, of course, didn't hear any more."
There was silence in the apartment for several minutes. Then Vance, who had been watching Jessup closely during the interview, spoke.
"By the bye, Mr. Jessup," he asked carelessly, "were you yourself, by any chance, a bit fascinated—let us say—by the charming Miss Odell?"
For the first time since entering the room the man appeared ill at ease. A dull flush overspread his cheeks.
"I thought she was a very beautiful lady," he answered resolutely.
