“Why, by the window, of course.”

“Well, that’s what I said,” responded Chester, “but Perkins is sure he didn’t take the key out of the door. And when we went up there afterwards the door was locked fast. I guess he put the key in his pocket and forgot it. He can’t find it, though. I gave him fits for letting you get away.”

“Well, don’t worry about the key, Chesty. Here it is.” Sam dug it out of his pocket and passed it over.

“H—how did you get it?” gasped Chester.

“Just took it out of the door.”

“But—but you said you got out by the window!”

“I said that? You must be dreaming. I went out by the door, of course.”

“But—but it was locked on the outside!”

“Was it? Funny I didn’t notice that. Are you sure?”

“Of course I am!” responded Chester puzzledly. “How did you get out, Sammy?”
