Philip thought for a minute. “He had awfully broad shoulders, and I don’t think a kid would have jumped on Mal.” He shrugged. “But I really think whoever it was won’t come back.” He put the floor boards back in place. “If he does, he won’t do any digging for buried treasure at this spot. Jimmy, go and get the old Bus and park it right here.”

Jimmy grinned with delight. “Right. And if our curious friend comes back to search, he’ll have to move the Bus. And, unless he’s a Samson he’ll have to start her up, and, when this thing starts running, he’ll realize that he’s set off the loudest fire alarm in Michigan.” He ran off to get the Bus.

“If we don’t find any treasure when we dig up the well,” Marjorie said, “let’s dig under the floor here.”

“Definitely no,” Phil told her firmly. “We’ll dig up the well and let it be known far and wide that we found nothing. That should put a stop to all the silly rumors.”

Pat nodded approvingly. “And night prowlers.”

When they returned to the house they found that Kitty and Mal had sandwiches and a large pot of hot cocoa waiting for them.

“I think you men should take turns keeping watch tonight,” Kitty said nervously. “And please, can’t we sleep in the house tonight instead of in the cabin?”

“Of course, you can,” Phil said. “And perhaps it isn’t a bad idea for us to take turns keeping an eye on the place.” He smiled reassuringly. “For the rest of tonight anyway.”

“I’ll take one shift,” Marjorie said, suppressing a yawn. “I won’t sleep a wink anyway.”

But she did, the minute her head touched the pillow, and when she awoke in the morning was very disappointed to hear that the night had been uneventful.
