“You’ve got something on your mind, Bruce! What is it?” challenged Hiram Dobbs.

“Oh, just thinking,” answered Bruce in a way meant to be off-handed, but palpably evasive and embarrassed.

“You can’t fool me!” insisted Hiram in his persistent fashion. “Ever since you took those diamonds back to the police you’ve been mooning. You don’t mean to tell me you’ve caught the detective-fever?”

“Me!” laughed Bruce. “No more chance of that than of running an airship. I’d better correct one false impression you’ve got, though, Hiram.”

“And what is that?”

“I didn’t take those diamonds to the police at all.”

“Didn’t? Well, that’s news!” declared Hiram wonderingly.

“You see, you were all so busy here I didn’t want to bother you about a little thing like that. I took the diamonds back to the people who lost them. I’ve had an idea about those diamonds for some time.”

“You have some good ideas, Bruce—what’s this one?”

“Why, I have felt satisfied all along that the thief had those diamonds when he was escaping in the Scout.”
