"Yes."

"How?"

"I decline to say. I've had enough interference with my plans already. Neither you nor the police have accomplished anything. Miss Goncourt knows what I propose to do; but she has given me her word not to interfere. If you are to accomplish anything, it must be before eight o'clock tomorrow night."

"Very well. I will make my plans accordingly."

"What do you propose to do?"

"That I cannot say, at the moment. I think, however, that I shall first try to find out who it is that smokes these gold-tipped cigarettes." He drew the fragment of cigarette which he had found from his pocket, and placing it on the desk before him regarded it critically.

Mr. Stapleton gave a grunt. "What are they, Exquisites?"

"Yes. How did you know?"

The banker laughed. "Easy enough. My wife smokes them."

The detective looked up quickly. "Indeed! Brings them from America with her, I suppose."
