When Sophie Lilburn leaves London for the sleepy West Country town of Westmead, so that her husband Chris can pursue his long-held dream of singing in a cathedral choir, she is aware that it will bring changes to her life. But she is not prepared for the claustrophobia Quire Close, or the extent to which her career, her relationships, and even her marriage will be affected. Then she learns that eleven years earlier a young girl was murdered in the Close who has never been identified and her killer has never been apprehended.

Meanwhile, in the equally narrow world of the bleak East Anglian fens, Jacquie Darke sets forth on a quest to find her missing sister. It is a journey which will lead her to heartbreak, self-knowledge, and danger.

A killer has struck once and has got away with it. Will he strike again?
