Former spy Maggie Bird came to the seaside village of Purity, Maine, eager to put the past behind her after a mission went tragically wrong. These days, she’s living quietly on her chicken farm, still wary of blowback from the events that forced her early retirement. But when a body turns up in Maggie’s driveway, she knows it’s a message from former foes who haven’t forgotten her. Maggie turns to her local circle of old friends --- all retirees from the CIA --- to help uncover the truth about who is trying to kill her, and why. This “Martini Club” of former spies may be retired, but they still have a few useful skills that they’re eager to use again, if only to spice up their rather sedate new lives.
