“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.

“Perhaps,” was the reply.  “That’s the chance I must take.  But we can’t let a little thing like that stand in the way.  As soon as I tackle them, or him, you two can rush out and lend a hand.  There’ll be a hard fight, of course, and the first fellow that gets a chance to make a break through the door will do so.  Do I make myself clear?”

“Perfectly,” said Hal.  “And the plan is not so bad.  There is a certain chance of success.”

“Well, it doesn’t look good to me,” replied Uncle John.  “One of you boys is almost sure to get killed.”

“You are taking the same chance, sir,” replied Chester.

“Oh, I’m not worrying about myself,” returned Uncle John.  “But you must remember that I am to some extent responsible for you and I shall have to answer to your mothers for your safety.”

“If you wish,” said Chester dryly, “we’ll each write you a little note exonerating you of all blame should either of us be hurt.”

Uncle John was forced to smile.

“Oh, never mind,” he said.  “Well, boys, if you have decided upon your plan, I guess I shall have to agree to it.”

“I believe it will succeed,” said Chester.  “But at all events, we can’t remain here inactive while that villain Robard is about his work.”

“You’re right there, Chester,” said Hal.  “Something must be done, and as there is no one else aware of this plot, I guess it is up to us.”

“As I said before, you can count on me to the limit,” said Uncle John.

“I’m counting on you, Uncle John,” replied Chester.  “I know you will do your part.”

“Thanks,” was the quiet response.

“Any more suggestions?” asked Chester.

There were none.

“What time is it?” asked Hal.

Chester glanced quickly at his watch.

“Great Scott!” he ejaculated.  “Ten o’clock!  I had no idea it was so late.”

“Nor I,” declared Uncle John.

“Time to get busy, then,” said Hal.

“Right,” Chester agreed.  “We haven’t a whole lot of time.”

He gazed quickly about the room and then took his position at one side of the door, where he would not be seen by one entering the room.  Hal and Uncle John also took their places.

“Everything ship-shape?” asked Chester.

“Guess so,” replied Uncle John, somewhat nervously—­he was not used to this kind of work, although each lad knew there was no question of his nerve and courage.
