Helter Skelter (1974) is a book by Vincent Bugliosi and Curt Gentry. Bugliosi had served as the prosecutor in the 1970 trial of Charles Manson. The book presents his firsthand account of the cases of Manson, Susan Atkins, Patricia Krenwinkel, and other members of the self-described Manson Family. It is the best-selling true crime book in history.
The book recounts and assesses the investigation, arrest, and prosecution of Charles Manson and his followers for the notorious 1969 murders of Leno and Rosemary LaBianca, actress Sharon Tate, and several others.
The book takes its title from the apocalyptic race war that Manson believed would occur, which in turn took its name from the song "Helter Skelter" by The Beatles. Manson had been particularly fascinated by the Beatles' White Album, from which the song came.
