“I’m really going to work,” Penny announced grimly. “No Mrs. Deline ever will outwit me! Our first job must be to find that package she buried in the sand.”
“And what of the person hiding in the woods?”
“The rangers ought to take over that part.” Penny peered out through the car window at the dark woods which hemmed in the camp. “Somehow,” she admitted, “I don’t like the idea of being here at night. I’m not exactly afraid, but—”
“Listen!” Louise ordered sharply, “Someone’s coming!”
Penny snapped off the radio. Tensely, the girls watched the road. The next instant they relaxed, for it was Mr. Parker who trudged wearily up the slope. Seeing Penny and Louise in the car, he came over to apologize for being so late.
“I’ve been with Jerry for the past two hours,” he explained. “Time went faster than I realized.”
“Any news?” Penny asked eagerly.
“Not about the radio station if that’s what you mean. The fellow got away with his portable outfit slick as a whistle.”
“The authorities have no idea who the man is, Dad?”
“Not the slightest. So far they’ve not been able to break the code he uses either. But in time they’ll get him.”
