The book takes us through the process from start to finish: the discovery of the bodies, the investigations, the eventual linkage of the two sets of murders, how the Manson Family's involvement was discovered, how the motive was unearthed, the charges, the trial, the sentencing, and the aftermath. If you're looking for a narrative perspective from the perspectives of the killers, that's not what you'll find here. It never really gets in the heads of Manson or his girls, and it couldn't, because they never really opened up to the prosecution team. There are still questions by the end of it, but they aren't questions that can be answered from the outside.
Helter Skelter is a big book, over 600 pages, but it reads fairly quickly. The writing is nimble, and though it doesn't scrimp from talking about some details of blood type analysis or fingerprinting as it applies to the case, it doesn't get bogged down in technicality. The biggest single flaw of the book is Bugliosi's self-aggrandizement. He clearly did a phenomenal amount of work and won a case that could have easily gone the other way if Manson hadn't been a difficult client for his lawyer to work with, but he definitely spends more time than is really necessary bemoaning the investigative deficits of the police and making sure the reader knows how much of the case was 100% a result of his own handiwork. By the end I'd started literally rolling my eyes whenever Bugliosi gave himself a big pat on the back. At the end of the day, it's an incredibly detailed account of the crime for anyone who's interested in reading one, though if your interest is in true crime generally rather than this crime specifically it might not be the best investment of reading time.
