The Dark Room Walters, Minette

Jinx Kingsley wakes in a private clinic with no memory of how she got there. Her face is battered. Her fiancé and best friend are dead — a murder-suicide, the police say. But Jinx doesn't remember any of it, and as her memory returns in jagged fragments, nothing about the official story adds up. Detective Superintendent Frank Cheever doesn't buy it either. The deeper he digs into Jinx's wealthy, fractured family, the more he finds old resentments, buried secrets, and people who had reasons to want both victims dead. Minette Walters writes psychological suspense with a scalpel — sharp, unsettling, and impossible to look away from. The Dark Room is taut, twisty, and anchored by a protagonist who has to piece together her own life while everyone around her might be lying.
