“What were you doing back there at the plane, if that’s where you were?” demanded Tom, while Ned held the prisoner fast.

“Yes, I was near your plane, but I didn’t do any damage—I—I just couldn’t,” Kenny faltered.

“Were you going to do any damage?” Tom inquired sternly.

“I was—if I could—yes,” was the reply. “They wanted me to blow it up or damage it in some way, so you couldn’t make the return trip. But I hadn’t the heart to do it—I just couldn’t bring myself to it, Mr. Swift—I just couldn’t.”

“Who do you mean wanted you to blow up my machine?” asked the young inventor. “Was it Schlump and those two masked men? Who are they, anyhow?”

“Yes, it was them. But I can’t tell you who those other two are,” was the reply. “It would mean death to me if I squealed. But I’m through. Do what you like with me, only don’t let those fellows get hold of me. I’m done for if you do.”

“How do you know but what you aren’t done for now?” asked Ned grimly. “We’ve got you fast, and your confession is enough to send you to jail. Kidnapping is a serious crime, you know.”

“I don’t mind going to jail,” whimpered Kenny. “That would be better than being killed—never knowing when the blow was going to fall. If I’m in jail they can’t get me. And they’ll try to, for they’ll soon know I didn’t carry out my end of the bargain.”

“Well, you’re going to jail all right!” declared Tom. “It may be the best and safest place for you, and I surely will feel better when you’re behind bars. But what’s the game, anyhow? Why should Schlump and those two masked men want to do me harm?”

“I can’t tell you,” Kenny faltered. “I have betrayed them enough as it is, and I’m not going to say any more. I give up—that’s enough for you—and I warn you to look out. Now all I want is protection from them. Have me locked up; I deserve it.”
