"I have nothing to do with that," said the telegraph boy. "I was sent out to buy some articles, and this money was given me to pay for them."
"Have you got any other money of this description?" asked the trader, suspiciously.
"Yes," answered Frank, readily. "I have another twenty."
"Let me see it."
"Certainly. I should like to know whether that is bad too."
The other twenty proved to be a fac-simile of the first.
"I must know where you got this money," said the merchant. "You may be in the service of counterfeiters."
"You might know, from my uniform, that I am not," said Frank, indignantly. "I once lost a place because I would not pass counterfeit money."
"I have a detective here. You must lead him to the man who supplied you with the money."
"I am quite willing to do it," said our hero. "He wanted to make a tool of me. If I can put him into the hands of the law, I will."
