“A five-dollar bill, marked as you have described, was paid to Mr. Washburn, the jeweler, only yesterday.”

“Ha! Well?”

“The one who offered it purchased a gold ring.”

“I don’t care what he bought. Who was it that offered the money?”

“Your nephew, James Smith!”

“I don’t believe it,” said the teacher, very much disconcerted.

“Then, sir, I advise you to question Mr. Washburn.”

“How can he identify the bill? Is it the only five-dollar bill he has?”

“The only five-dollar bill on the Park Bank of New York, and he says he noticed that this was the bank that issued the bill handed him by your nephew.”

“What of that?”
