This case was different from anything Vera had ever worked before. Two bodies, connected but not lying together. And nothing made her feel as alive as murder. Life seems perfect in Valley Farm, a quiet community in Northumberland. Then a shocking discovery shatters the silence. The owners of a big country house have employed a house-sitter, a young ecologist named Patrick, to look after the place while they're away. But Patrick is found dead by the side of the lane into the valley - a beautiful, lonely place to die. DI Vera Stanhope arrives on the scene, with her detectives Holly and Joe. When they look round the attic of the big house - where Patrick has a flat - she finds the body of a second man. All the two victims have in common is a fascination with moths - catching these beautiful, rare creatures. The three couples who live in the Valley Farm development have secrets too: Annie and Sam's daughter is due to be released from prison any day; Nigel watches, silently, every day, from his window. As Vera is drawn into the claustrophobic world of this increasingly strange community, she realizes that there may be deadly secrets trapped here . . .
