It was one of the most unnerving times in American history. A counterculture was spreading through society like a contagion. Its most esoteric and flamboyant center was San Francisco. From within this psychedelic culture of peace, drugs and daisies, there arose the most boastful killer in history. His murders would be those of some demented thug stalking lovers' lanes were it not for his publicity campaign. He not only murdered. He marketed his murders. And his claims make no sense when compared to his murders. He called himself the Zodiac and claimed occult motives, thus implying he arose from the disturbing hippie movement. Then he threatened to plant bombs and snipe school busses, foreshadowing the methods of the militant New Left. He bragged he was too clever to ever be identified or captured. Then he disappeared. His murders have never been solved, and he became the center of a personality cult of crime. The investigation and pursuit of the infamous 'Zodiac' is not the pursuit of a serial killer. To put a face and name on him is not enough. Something far more complex was involved in the crime spree than the motives of a thrill-seeking sex killer. For 13 years the author investigated the case. In HorrorScope he reestablishes the actual facts to vividly recreate the crimes and the volatile times of the Zodiac. Following significant discoveries eventually leads him to the Zodiac and a very convoluted motive for the crimes.
