The Dying Light by Ann Cleeves

Detective Matthew Venn is called to investigate when the body of a young woman is found in the swimming pool of Tide House, a luxurious holiday home in North Devon. The girl’s best friend has disappeared and the property belongs to rising political star Paul Armstrong, leading to intense media scrutiny.

The dead girl and her friend had been spotted at a music festival the previous day, an event which brought locals and outsiders together - some of whom may have been more connected with the Armstrongs than first thought.

Caught between a powerful family’s secrets and a powder keg of local tensions, Venn must navigate a treacherous path - knowing that the real answers lie not in what people say, but in the silence that they keep . . .
