Though a few years past sixty, Sarah Kelling’s Aunt Emma is as vigorous as a girl of twenty-two. She sings, she dances, and when the local fire department needs a fundraising boost, she’s happy to jump out a window for charity. This summer, she decamps to Maine, to beat the heat at an island retreat for artists and great thinkers. There are writers, painters, a psychic, and a historian, and their company promises to be great fun—until a few of them go treasure-crazy.

Sensible people have long dismissed rumors of the Pocapuk Island treasure as myth, but artists are seldom sensible. When their rampant digging stirs up buried trouble, it leads to theft, drugging, and a murder. And although Sarah and her husband Max give investigative advice by phone, it’s up to Aunt Emma to save the islanders from themselves.
