To begin this review, I must explain that I do not normally read books in the True Crime genre. In fact, this is the first and only True Crime book I have read. My reading interests are traditionally geared towards philosophical, religious and historical texts. I became interested in Charles Manson after watching some of his interviews about spirituality on YouTube. I picked up Helter Skelter because it appeared to be the most critically acclaimed text on the subject of Charles Manson. If you are someone who is simply looking for a gripping, page-turning story about murder and mayhem, BUY THIS BOOK. It is a well-written and accurate factual chronicle of the Manson murders that is every bit as good as all the other reviews on Amazon say. (Be aware, however, that this book is dated. A lot of information about the murders have come out since this book was published, and even the updated new versions don't cover the new material in any great depth.) If I were reviewing this book strictly on the quality of the story told, I would award it 5-stars.
Having said that, this book could have been much more engaging. It is simply that, a well-written factual chronicle of the Manson murders. For some reason, the book opens on the day after the Sharon Tate murder. The author (the attorney who prosecuted Manson) presents the facts chronologically, with many many exceptions, in the same order that detectives working the case learned of them. This means that the book is less the story Charles Manson and his family, and more the story of prosecutor Vincent Bugliosi. This manner of story-telling brings to the forefront the limitations of the author. Again, Bugliosi is an attorney with a mind only for the concrete facts. If you are hoping for a critical examination of Manson, the control he had over his followers, his beliefs, his childhood, etc., choose a different book. On the few occasions the author attempts to stray from a factual account of the murders in order to address the more abstract ideas and implications surrounding the murders, he gets it wrong. (Browsing Amazon, I see that Bugliosi has recently published a book on religion. Read the reviews of that book and you will see that, even forty years after writing Helter Skelter, Bugliosi is apparently still unqualified to write about more abstract topics.)
My advice is to read this book if you want a purely factual account of the Manson slayings, or are just looking for some good entertainment. However, if you are also interested in the psychology behind Manson and his family, you will need to supplement Helter Skelter with other reading. Finally, be aware that, at 700+ pages, this book will likely take at least a few weeks to finish.
