“Well, well. Fancy that! And, such being the case, one might conclude—without too great a curfuffling of one’s brains—that, preceding his issuing from that particular door, he was actually in Miss Sibella’s room?”

“I suppose so, sir.”

“Dash it all, Sproot! You know deuced well he was there.”

“Well—yes, sir.”

“And now suppose you continue with your odyssey.”

“It was more like the Iliad, if I may say so. More tragic-like, if you understand what I mean; although Mr. Rex was not exactly a Hector. However that may be, sir, Doctor Von Blon came immediately——”

“He had not heard the shot, then?”

“Apparently not, for he seemed very much startled when he saw Mr. Rex. And Miss Sibella, who followed him into Mr. Rex’s room, was startled, too.”

“Did they make any comment?”

“As to that I couldn’t say. I came down-stairs at once and telephoned to Mr. Markham.”
