"He's a black villain," declared Uncle John.

"And now," said Chester, "he is on his errand of mischief. Can we do nothing to thwart him?"

"I can't see how," declared Uncle John.

"Nor I," said Hal.

"Wait a moment, though," said Chester.

"Well?" queried Hal anxiously.

"I think it can be done," replied Chester quietly. "At least there is a chance."

"Let's have it," demanded Hal eagerly.

"Well, here is the idea. We'll stir up a racket in here. Naturally some of our captors will come to see what it is all about. We won't quiet down until he opens the door. Now you will notice that the door swings inward. That will help. Also that from outside it is impossible to see this side of the room. I'll stand behind the door. You and Uncle John remain on this side and stay here until the man comes into the room. Then I'll jump him, or them, as the case may be."

"But they'll get you, Chester," said Uncle John.
