As usual for the much-traveled young Biff Brewster, he had major components of adventure and intrigue when his Uncle Charlie contacted him to come to the Caribbean and help with a search for some valuable pearls in and around Martinique. They were first found by Brom Zook, father of Derek Zook, who first surprisingly met with Biff by accident. They were thoroughly astounded to find they looked identical enough to be twins. As the search Biff planned to join his uncle on, they became involved with an evil man named Dietz. He was sided by Crunch and Specks, a pair of relatively stupid men willing to do anything to help their master. The question was basically, "Were the pearls found," and "Who found them?" An answer eventually occurs as you can find out by listening.
