"Well, we'd all be dead now if it hadn't been for his nerve and quick action. What a brave man he was!"

"That mustn't happen again," exclaimed Armande. "We must clean those rats out of the tower before it will be safe for us here."

"How are you going to do it?" inquired Jacques.

"Go up after them of course. Who will go with me!"

"I will, I will," cried a half-dozen voices eagerly.

"Come along then," exclaimed Armande, and advancing to the stairway he placed one foot on the bottom step and glanced up.
