"Is there anything the matter?"
"I want you to see if you have been robbed.'"
Tom was broad awake in an instant.
"Robbed!" he exclaimed, in alarm. He felt for his belt and was relieved.
"No," he answered. "What makes you ask?"
"Because I have had a wallet taken. It makes me laugh when I think of it."
"Makes you laugh!" repeated Tom, under the transient impression that his companion was insane. "Why should you laugh at the loss of your money?"
"I saw the thief sneak out of the stateroom," continued Mr. Waterbury; "but I didn't interfere with him."
"You didn't!" said Tom, completely mystified. "I would. Did you see who it was?"
"Yes; it was your friend and late roommate."
