“There ought to be some money in that secretaire?”

“There may be. No one knows what there is.”

“And where is it?”

“On the first floor.”

“Sketch me the plan of that floor, as you have done of the ground floor, my boy.”

“That is very simple.” Andrea took the pen. “On the first story, do you see, there is the anteroom and the drawing-room; to the right of the drawing-room, a library and a study; to the left, a bedroom and a dressing-room. The famous secretaire is in the dressing-room.”

“Is there a window in the dressing-room?”

“Two⁠—one here and one there.” Andrea sketched two windows in the room, which formed an angle on the plan, and appeared as a small square added to the rectangle of the bedroom. Caderousse became thoughtful.
