“Now, through a hole in the window, a person could, by the aid of some instrument, let us say a poker with a hook at the end, grip the ring, pull down, and open the transom.”

“Excellent! excellent! Your scheme is very cleverly constructed, but you overlook one thing, monsieur, there is no hole in the window.”

“There was a hole.”

“Nonsense, we would have seen it.”

“In order to see it, you must look for it, and no one has looked. The hole is there; it must be there, at the side of the window, in the putty. In a vertical direction, of course.”
