"Stop, Bobby!"

"Hartley! I'm afraid to go to sleep. It's dreadful not to know whether you are active in your sleep, whether you are evil and ingenious to the point of the miraculous in your sleep. I'm so tired, Hartley."

"Why should you have gone to that room this afternoon?" Graham asked. "You must get this idea out of your head. You must have sleep, and, perhaps, when you're thoroughly rested, you will remember."

"I'm not so sure," Bobby said, "that I want to remember."

He pointed to the footprint.

"There's no question. I was here last night."

"Unless," Graham said, "your handkerchief and your shoes were stolen."

"Nonsense!" Bobby cried. "The only motive would be to commit a murder in order to kill me by sending me to the chair. And who would know his way around that dark house like me? Who would have found out so easily that my grandfather had changed his room?"

"It's logical," Graham admitted slowly, "but we can't give in. By the way, has Paredes ever borrowed any large sums?"
