“It was taken by the young man who sat next to you.”

“How do you know?”

“He robbed me last night on the way from New York in a Hudson River steamboat.”

“That doesn’t prove that he robbed me. I was robbed here in this city.”

“What do you say to this?” asked Carl, displaying the bank book.

“Bless me! That is my book. Where did you get it?”

Carl told his story briefly, how, on discovering that he had been robbed, he explored the stateroom and found the bank book.

“Well, well, I am astonished! And how did you know Mr. Norris was my nephew?”

“I didn’t know. I didn’t know anything about him or you, but finding his name in the directory, I came here to ask if he knew any such person.”

“You are a smart boy, and a good, honest one,” said Miss Norris. “You have earned the reward, and shall have it.”
