The dead woman looks totally peaceful and there are no marks of violence. But why is she here, in this remote spot? Why does no one come forward to identify her? And why is she wearing a thin white dress on this howling October night? When young Welsh police sergeant Fiona Griffiths starts to investigate, her enquiries take her to a quiet monastery buried deep in the Welsh hills. And when she finds that a young teenager from the area went missing a few years earlier, her anxieties start to deepen.

At first, the murder scene appears sad, but not unusual: a young woman undone by drugs and prostitution, her six-year-old daughter dead alongside her. But then detectives find a strange piece of evidence in the squalid house: the platinum credit card of a very wealthy - and long dead - steel tycoon. What is a heroin-addicted hooker doing with the credit card of a well-known and powerful man who died months ago? This is the question that the most junior member of the investigative team, Detective Constable Fiona Griffiths, is assigned to answer.

The story opens with the apparently accidental drowning of a sixth form student in the Norfolk countryside. As a matter of routine, or so it seems, the case passes across the desk of Detective Sergeant Smith, recently returned to work after an internal investigation into another case that has led to tensions between officers at Kings Lake police headquarters. As an ex-DCI, Smith could have retired by now, and it is clear that some of his superiors wish that he would do so.

"And see if there's any news about the missing girl." Life, as Smith used to say, is just one thing after another - as one investigation ends, a new one begins. But for reasons unknown to the rest of her team, DCI Cara Freeman will be haunted by the next case for the Kings Lake Central murder squad. They find themselves delving into the seamy side of life in the town, and one of their number will have departed before this new investigation is over. Perhaps Detective Sergeant Chris Waters should have seen it coming, but he has a lot more than work on his mind these days.
