THE MARTINI CLUB ISN’T WHAT YOU THINK . . .

Maggie Bird’s ‘book group’ is an unusual one – a group of retired spies living an anonymous life in the quiet town of Purity. But a shocking murder at the Cod Cove Resort hotel coincides with the disappearance of Maggie’s friend Ingrid.

Ingrid’s husband Lloyd is devastated. He has no experience in covert operations, but he is determined to find his wife – wherever in the world she is. With a concerned Maggie at his side, Lloyd unwittingly sets off a chain of events that threats Ingrid’s life.

Meanwhile in Maine, local cop Jo Thibodeau and her unlikely allies uncover startling evidence that turns all their assumptions upside down . . .

Living in Purity has never been more dangerous. Could this be the end of the Martini Club?
