"Before I answer any questions, I want to ask you one. Did you, by any chance, mention me to the gentleman known to you as M. Félix Armand?"
"Yes," I answered, after a moment's thought; "I believe I did. I was telling him about our trying to find the secret drawer—I mentioned your name—and he asked who you were. I told him you were a genius at solving mysteries."
Godfrey nodded.
"That," he said, "explains the one thing I didn't understand. Now go ahead with your questions."
"You said a while ago that you would know all about this affair day after to-morrow."
"Yes."
"How do you know you will?"
