The Crow Trap — Ann Cleeves

Three very different women come together to complete an environmental survey on the Northumberland countryside. Three women who, in some way or another, know the meaning of betrayal.... For team leader Rachael Lambert the project is the perfect opportunity to rebuild her confidence after a double-betrayal by her lover and boss, Peter Kemp. Botanist Anne Preece, on the other hand, sees it as a chance to indulge in a little deception of her own. And then there is Grace Fulwell, a strange, uncommunicative young woman with plenty of her own secrets to hide...

When Rachael arrives at the cottage, however, she is horrified to discover the body of her friend Bella Furness. Bella, it appears, has committed suicide--a verdict Rachael finds impossible to accept.

Only when the next death occurs does a fourth woman enter the picture--the unconventional Detective Inspector Vera Stanhope, who must piece together the truth from these women's tangled lives...
