Five boys. Five weeks camping in the pine forests of Michigan's Upper Peninsula. What could go wrong?Walter Stanley's eccentric bachelor uncle has offered to take him and a chosen friend on the adventure of a lifetime. Only it's too hard to choose just one friend! So along come Ferdinand Eggert with his wireless radio, a persistent John Newell (who insists on paying his own way) and the perennially cheerful Carroll Cage…plus a newcomer to tag along as cook. But before they've even arrived at their destination, it becomes clear that one of the boys is a thief…how will they discover the culprit?
