Tension mounted as the evening hours on the island dragged slowly by. At 11 P.M. Charlie Keene arose from his cot. He had ordered Biff and Derek to try and rest.

“Let’s go.”

The boys followed Uncle Charlie down to the cabin cruiser and the dory.

“You both know what you’re to do?” he asked.

“Yes, Mr. Keene,” Derek replied.

“All set, Uncle Charlie,” Biff said.

“Crunch may or may not be with them. I imagine he will be. But I’m sure we don’t have to worry about him now. Okay, Derek, into the cruiser. Biff, you and I will hide behind the dory. Derek, you know when to start and what to do.”

“I do.”

“All right. Take your positions.”

Derek waded out and climbed aboard the cruiser. Biff and his uncle dug into the sand on the beach side of the dory.
