Synopsis
This book gives the history of the Zodiac killer who was active in the 1960s and 70s in California. It describes the investigations of the many law enforcement branches that worked on the case and other murders that might have been committed by Zodiac, including the 1966 Cherie Jo Bates stabbing. Later chapters deal with Graysmith's many theories on the case, and the book eventually cites two possible suspects (who are given pseudonyms) and details some of the circumstantial evidence against them. Graysmith received assistance from police departments that fell within the jurisdictions of the murders, especially from Inspector Dave Toschi from the San Francisco Police Department, who had worked the Zodiac case.
