“Just be patient,” Jerry smiled. “And whatever you do, don’t drop a hint to Mrs. Deline of what we suspect.”

“She knows I dislike her.”

“That’s all right, but don’t let her guess that you consider her guilty of anything more serious than making a play for your father.”

“What about Dad? Shouldn’t I warn him?”

“Let me take care of that part,” Jerry smiled.

“All right,” Penny agreed reluctantly. “Just be sure that you don’t muff it. Remember, you’re playing with my future!”

Jerry finished smoothing out the footprints in the sand and then escorted the girls to the hotel.

“I must report to Headquarters without delay,” he said, pausing at the hotel entrance. “Don’t worry about the package. We’ll have the place watched every minute.”

After Jerry had gone, Penny and Louise entered the hotel.

“Is my father here yet?” Penny asked the desk clerk.
