My Dark Places: An L.A. Crime Memoir is a 1996 book, part investigative journalism and part memoir, by American crime-fiction writer James Ellroy. Ellroy's mother Geneva was murdered in 1958, when he was 10 years old, and the killer was never identified. The book is Ellroy's account of his attempt to solve the mystery by hiring a retired Los Angeles County homicide detective to investigate the crime. Ellroy also explores how being directly affected by a crime shaped his life - often for the worse - and led him to write crime novels. The book is dedicated to his mother. Source: Wikipedia (en)
