When she's not digging up bones or other ancient objects, Ruth Galloway lectures at the University of North Norfolk. She lives happily alone in a remote, wild place called Saltmarsh, overlooking the North Sea under Norfolk's vast skies. When a child's bones are found in the marshes near an ancient site that Ruth worked on ten years earlier, Ruth is asked to date them. Soon it becomes clear that Ruth is in grave danger from a killer who knows that her expert knowledge is being used to help the police with their enquiries.
