“Why, what you going to do with them?”

“We’ll leave one with Mr. Sleeper and take the other with us.”

“Good idea.”

The radios mentioned were a recent invention which they had worked and were very compact, a small selenium plate taking the place of the ordinary aerial.

Mr. Sleeper displayed great interest when they showed him the outfit and explained how it worked.

“Sure I’ll keep one and if you get into any trouble just let me know,” he said as soon as they had told him their plans. “I’d like to go with you but I’m afraid I couldn’t stand it. I’m not much of a walker. Broke my leg a few years ago and it never was set right. Gives out if I attempt to walk very far.”

“But my legs are all right and I want to go.”

“I was afraid you were listening behind that door.”

“But I can go?” Helen asked eagerly.

“Not this time, kitten. This is no trip for a girl.”
