“You remember where it was buried?”

“Approximately.”

“I’ll not have time to go with you now,” Jerry said, looking at his wrist watch.

“Louise and I haven’t much to do this morning. We’ll be glad to search.”

“Go ahead,” Jerry urged. “If you fail then I can take over. The important thing is not to tip off your hand. Don’t let anyone suspect what you’re about.”

Penny and Louise nodded soberly. They felt rather important to have been assigned a definite task.

“Report to me as soon as you find that package,” Jerry urged as he started on. “It may contain something of vital importance. It may not. We’ll withhold judgment until we have the facts.”

Left to themselves, the girls lost not a moment in hastening to the section of beach where Mrs. Deline had been seen to bury the package.

“Now just where was it?” Penny asked, gazing about the deserted dunes. “What became of our marker?”

“We left a stick to show the exact spot.”
