“After all,” I said, in the same even tone, “it was found in his house. Now, I have a theory. Shall I tell you what it is?”

He could not well say “no,” though I noticed he was not anxious to listen to the expression of my views or theories on the subject.

“Well,” I continued, looking at him steadily, “I have a theory regarding that strange hole in the ceiling. Can you guess what it is?”
