"Yes."

"It was not the wind. Some one was attempting to open it. I am going to find out who it is and why they are there."

"How?"

"By stratagem. I wish you to go upstairs and remain there until I call you."

"Why should I do that?" he asked, hesitating and perplexed.

"Because I ask you. You will do it?"

"I don't like it—but if you insist, I promise."

"Before you go I wish you to lie on the couch there while my servant comes here and does what I will tell him; and you will act as though you were bidding him good-night—but as if you were still drugged."

"Hadn't you better tell me everything?"

"There is no time. Will you do this? Please."
