Annie is assisting Wendy Pyle and Maggie Sloan plan a ceremony for the opening of Blue Hill's time capsule. The capsule is stores in a statue of Lois Stover, one of the town's most famous citizens. Stover not only served as a special agent during World War I, but she also was the first female architect registered in Pennsylvania and provided inspiration for many of Aunt Edie's adventures. But mere days before the ceremony, both the statue and its time capsule disappear! How did the thieves manage to steal the life-size statue right off of its stone base and why? Could rumors about a treasure trove of hidden jewels inside it be true? Meanwhile, Ben desperately wants a metal detector, but Anne isn't comfortable with the idea of her son wandering all over town, digging up dubious finds. Besides, metal detectors are expensive and they simply can't afford one. When a neighbor offers to sell his used one for next to nothing, though, Anne can't refuse. To her surprise, Ben's new hobby might help solve the mystery of the missing statue.
