The Dark Room by Minette Walters

In this acclaimed psychological mystery, Jinx Kingsley, a prominent photographer and millionaire’s daughter, wakes up in an exclusive hospital suffering from amnesia. Not only can she not remember the car accident that caused her memory loss, but she doesn’t remember that her impending wedding has been called off or that her former fiancé and his girlfriend have been brutally murdered in the same way her first husband had been ten years before. Now she must try to piece together her memories in order to determine her innocence. With deft psychological explorations and shocking twists, Walters brings the story to an awe-inspiring conclusion.
