“We won’t loose him,” the policeman promised.
They found Captain Brice and Jack waiting for them at the hotel.
“Well, thanks to you boys, that job’s done,” Captain Jim declared as they were eating a late supper.
“But there’s one thing that isn’t done,” Jack said. “I want to know how that cabin went up into thin air and what’s more I’m going to find out if it takes all summer.”
“It won’t take that long,” Captain Jim laughed. “As a matter of fact it will only take about two minutes.”
“Then you’ve solved it?”
“Bob has, or a part of it at least and I’m inclined to think the whole of it.” And he proceeded to tell them all about it.
“What do you know about that?” Jack asked as soon as he had finished.
“Mighty clever I call it,” Captain Brice declared. “And to think that we never suspected it.”
“Only a man with Slippery Elm’s fertile brain would think up a thing like that,” Captain Jim said as he pushed back his chair.
