She was about to let them fall from her hand, when a bit of paper
fluttered from one envelope. Picking it up Betty was astonished to read
on the torn portion the words:

"_I cannot carry out that deal I arranged with you, because I have had
the misfortune to lose five hundred dollars and I shall have to_--"

There the paper, evidently part of a letter to someone, was torn off.
There were no other words.

"Girls!" cried Betty, "look--see! This letter! That man may be the one
whose money we found! He has written about it--as nearly as I can recall,
the writing is like that in the note pinned to the five hundred dollars.
Oh, we must find that tramp!"

"He wasn't a tramp!" exclaimed Grace.

"No, I don't believe he was, either," admitted Betty. "That's what he
meant when he spoke of his disguise, and looking for something. He's
hunting for his five hundred dollars. Oh, dear! which way did he go?"

"Toward Middleville," returned Amy.

"Then we must hurry up and catch him. We can explain that we have
his money."

"But are you sure it is his?" asked Mollie.

"This looks like it," said Betty, holding out the torn letter.
