Then as suddenly as the murders began, Zodiac disappeared into the Bay Area fog. After painstaking investigation and more than thirty years of research, Robert Graysmith finally exposes Zodiac’s true identity. With overwhelming evidence he reveals the twisted private life that led to the crimes, and provides startling theories as to why they stopped.
