Quintessentially British cop Richard Poole is a fish out of water when he is sent to the tiny island of Sainte Marie to solve a mysterious murder. Poole encounters a very different type of policing at his new post, challenging his more buttoned-up sensibilities. His new partner, Camille Bordey, is instinctive, feisty and brilliant, and the rest of the Saint Marie police force have their own unique way of doing things. Though Richard would never admit it, they make a perfect team.
