Mr. Moss laughed very much at this also, and swung himself down from the counter and went in search of the pie-plates. He returned eventually with three that seemed to be of the required size and quality.
"Wrap 'em up," said Frank, throwing the five dollar bill on the counter.
Mr. Moss wrapped up the plates, then picked up the bill and went over to the cash register. He rang up the amount of the sale and was about to put the money in the till when he suddenly hesitated, then held the bill up to the light. Slowly, he came back to the counter, rubbing the bill between thumb and forefinger, feeling its texture and minutely examining the surface.
"Where did you get this bill, boys?" he asked seriously.
"We just changed it for a stranger on the train," answered Frank. "What's the matter with it?"
"Looks bad to me," replied Mr. Moss dubiously. "I'm afraid I can't take a chance on it."
He handed the bill back to Frank, then indicated the package on the counter.
"What are you going to do about the plates?" he asked. "Have you any other money besides that bill?"
"Not a nickel," said Joe. "At least, not enough to pay for the plates. But do you really think the bill is no good?"
"I've handled a lot of them. It doesn't look good to me. I tell you what you'd better do. Take it over to the bank across the street and ask the cashier what he thinks of it."
