"Great Scott! What can have happened to him?" exclaimed Chester.
"Probably got caught," replied Hal.
"Then we must go back after him. Come on."
"Wait a minute," said Hal. "Don't forget this paper we recovered. It must be returned to General Ferrari, Uncle John or no Uncle John."
"But we can't let them kill him!" cried Chester.
"They won't kill him," said Hal positively. "They would be afraid to do that. First I must deliver this paper, and then we shall try to rescue Uncle John. But the paper is first. You know that."
"You are right, of course," Chester agreed. "Besides Uncle John knew what he was up against before he came with us. He'll have to wait until we can help him."
"All right, then. Now my idea is for you to wait here while I return this paper to General Ferrari. Then I shall come back and we will see what can be done. If they should take Uncle John from the house you follow them."
"Suits me," said Chester. "Get back as soon as you can."
Hal waved a hand and hurried away in the darkness.
