Cherringham is a quiet and peaceful town in the Cotswolds. Time moves slowly here, and nothing out of the ordinary ever happens, until one morning a woman's body is discovered in the river. Sarah Edwards has just returned to Cherringham with her two children following the breakdown of her marriage. Sarah had been friends with Sammi Jackson - the woman in the river –before they both moved to London and she's certain there is more to her death than meets the eye. But juggling the school run and her job as a web designer does not leave much time to solve murder mysteries. After the death of his wife, NYPD former homicide detective Jack Brennan has retired to Cherringham hoping for a quiet life. He soon realizes "peace and quiet" isn't really him and, despite his misgivings, he's persuaded by Sarah to help her look into Sammi's death. It quickly becomes clear that the case isn't as simple as the police hope. From her violent ex-boyfriend to her alcoholic father, it seems everyone has something to hide. Sarah and Jack will need to use all their wits to get to the bottom of this case.
