The rural idyll of life in a remote Welsh valley has turned sour for the Cordiners. For David, life in the local police force is deathly dull after the exhilaration of working for the Met. For Tessa, the hostility of the local community is a daily torment.
Then a young nurse is found dead at a nearby beauty spot, her corpse strewn with wild flowers in some sick ceremony. Caught up in the challenge of a murder investigation, David misses the signs that danger is stalking his wife in their secluded cottage.
