The Last Rites — M.J. Arlidge

When a troubled young woman disappears, Alice Rogers' parents fear the worst but their concerns are ignored by the police. Two weeks later a body is discovered in the River Calder, and the new Detective Inspector Jane Hacker suspects foul play despite her team thinking otherwise. DI Hacker has recently returned to her hometown, a community full of secrets where dangerous truths lie buried including the truth about her brother who died by drowning.

Suspicion lands on Alice's ex-partner Liam, a man with a history of violence. But when a second body is discovered in suspicious circumstances, DI Hacker believes a serial killer might be at work. Hacker sets herself on a collision course with the local police, the community - and a merciless killer. To uncover the truth, DI Hacker will be forced to question everything she stands for. She can trust nobody, and the shocking secrets revealed over seven days will fracture her entire world.
