Genevieve has finally escaped the stressful demands of her sales job and achieved her dream: to leave London behind and start a new life aboard a houseboat in Kent. But on the night of her boat-warming party the dream is shattered when a body washes up beside the boat, and she recognises the victim.

As the sanctuary of the boatyard is threatened, and her life is increasingly at risk, the story of how Genevieve came to be so out of her depth unfolds, and she learns the real cost of mixing business with pleasure.
