“By George, you’re right,” said Adrian. “I wonder where he is?”

“It don’t look as though anyone had been here since we were,” said Billie.

“Maybe there hasn’t,” replied Donald. “This surely is a queer mess we have fallen into.”

The noise of a great commotion in the street and

the sound of pounding on doors came to them through the grated window.

“The mob is returning!” said Adrian.

“What do you suppose the pounding is?” queried Billie.

“I should say they were breaking into the houses along the street,” said Donald.

“That is just what they are doing,” asserted Adrian. “Looking for us, no doubt.”

“We’d better barricade the door,” exclaimed Donald, and he grabbed the bed and pushed it against the door, while Billie pushed up the table.
