5 Exquisite detail and terrifying because its trueTopCat1984 | 13/07/2007 | See all TopCat1984's reviews (68)Top 100 Books Reviewer Usually with biographies and accounts, the detail is sparse, as the author is writing retrospectively or pretending they actualy know something about the subject. But not with this book. Graysmith was part of the investigation and his insight and true accounts is both terrifying and relentless. No details left out. Its very analytical and methodical in its writing style, as Graysmith like the Police was and still is trying to determine Zodiac's true identity. This book is not biased and offers only the truth no matter how horrifying. An absolute classic.
