Dr Ruth Galloway is in her late 30s. When shes not digging up bones or other ancient objects she lectures at a university in Norfolk. She lives alone but happily so in a bleak marshy area called Saltmarsh overlooking the sea & Norfolks vast skies with her cats & Radio 4 for company. Shes a salty character
- quirky. When a childs bones are found in the marshes near a dig that Ruth & her former boyfriend Peter worked on ten years before Ruth is called upon to date them. They turn out to be bronze-age bones & DCI Harry Nelson who called on Ruth for help is disappointed. He had hoped they would be the bones of a child called Lucy whos been missing presumed dead for ten years. He has been getting letters about her ever since
- odd letters with references to ritual & sacrifice & including"es from the Bible & Shakespeare. Then a second girl goes missing & Nelson gets another letter
- like the ones about Lucy. Is it the same killer? Is it a ritual murder linked in some way to the site near Ruths remote home? Then one of Ruths cats is killed & clearly shes in danger from a killer who knows that her expert knowledge is being used to help the police with their enquiries.. .
