More than forty years ago, Charles Manson and his mostly female commune killed nine people, among them the pregnant actress Sharon Tate. It was the culmination of a criminal career that author Jeff Guinn traces back to Manson's childhood. Guinn interviewed Manson's sister and cousin, neither of whom had ever previously cooperated with an author. Childhood friends, cellmates, and even some members of the Manson Family have provided new information about Manson's life. Guinn has made discoveries about the night of the Tate murders, answering unresolved questions, such as why one person on the property where the murders occurred was spared, and shows us how Manson created and refined his message to fit the times, persuading confused young women (and a few men) that he had the solutions to their problems.
