When Penny Derwood and her seventh-grade class tour a button factory, she accidentally gets involved in a mystery that she and her brother, Jack, are determined to unravel. In their efforts to solve the mystery, they undergo a series of hilarious adventures and at the same time begin to learn something about teamwork, family unity, and accepting one another.
Pull on your boots! It's winter in Peabody, Wisconsin, and there is plenty of excitement afoot at the Derwood household. Wise-cracking siblings Jack and Penny become entangled in an international smuggling operation and the nonstop adventure of cracking a dangerous case. At times, however, it is hard to decide which is a greater threat: seasoned criminals or neighborhood bullies. (Bob Jones University Press; 1983; 272 pgs)
