“Down on the beach?” said Arthur.

“No.”

“Give it up,” said George.

“Well, you wouldn’t guess in a hundred times trying,” said Tom, “so I’ll tell you. It was in Jack Harvey’s camp.”

“Harvey’s camp!” exclaimed the three brothers, in chorus.

“Yes, sir, Harvey’s camp.”

“I didn’t know they were off on a cruise,” said George. “Oh, I see, you’ve been getting even, have you? And how about the camp? Is it still there? What have you done with that?”

“It’s still down there,” laughed Tom. “We didn’t do anything to it at all. In fact, the crew were all there, and Harvey, too. We stayed there because they invited us. And, what’s more, we have just had breakfast with them all.”

The Warrens stared at Tom in amazement.

“Had breakfast with Harvey and his crew! Oh, say, you fellows, quit fooling now, and tell us where you have been.”
