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
