Helter Skelter: The True Story of The Manson Murders is a 1974 book by Vincent Bugliosi and Curt Gentry.

[1] 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, pregnant actress Sharon Tate, and several others.

[2] The book takes its title from the apocalyptic race war that Manson allegedly believed would occur, which in turn took its name from the song "Helter Skelter" by the Beatles.

[4] At the time of Bugliosi's death in 2015, it had sold over seven million copies, making it the best-selling true crime book in history.

Bugliosi himself narrated the Talking Books unabridged audiobook at the time of the book's original release, and read an abridged version of his update for the 25th anniversary edition abridged audiobook read by Robert Foxworth.
