"Oh, Dora! Don't say it!" protested Dorothy, in horror.

"I don't say I believe it. But you know very well that Billy is up to all sorts of mischief."

"But Billy Long is one of our own boys."

"I know he goes to Central High. But all the boys who go to our school are not angelic."

"Far from it," sighed her sister, pensively.

"And 'Short and Long' is a regular little snipe, sometimes!" said Dora, with emphasis.

"But to rob a store!" gasped her twin sister.

"He was seen around there the afternoon before. Why, I know that a policeman has been to his house looking for him, and nobody has seen Short and Long since Thursday night."

"But the robbery was committed some time Tuesday night."

"He wasn't suspected at first. Perhaps he thought nobody had noticed him helping the men in the afternoon."
