When Betty spoke like that, her comrades usually obeyed her.

Half scared at Betty’s frowning face, Maude told her story.

“What foolishness!” said Betty, as she finished. “Martha could no more take a penny that didn’t belong to her than I could!”

“Then what made her act so flustered when she invited us to have ice-cream and when she paid for it?” demanded Maude.

“I don’t know,” said Betty.

“And where would she get a new five-dollar bill all of a sudden?”

“I don’t know,” said Betty.

“And where is my bill?” wound up Maude, triumphantly, and again Betty was forced to reply, “I don’t know.”

“But all the same,” she went on, “Martha didn’t take it! And I’ll prove it somehow!”

“You can’t prove it unless you find my bill.”
