What this book is about
Lucy has never been able to get close to her mother-in-law Diana, a cold, accomplished woman who runs a charity for Afghan refugees and distributes her affection according to rules Lucy can never quite figure out. When Diana is found dead with a lethal dose of morphine in her system, the family begins to fracture — and Lucy finds herself a suspect. Sally Hepworth's dual-timeline domestic thriller alternates between Lucy's memories of her difficult relationship with Diana and the police investigation, slowly revealing what Diana was actually protecting and why.
