Robert Graysmith's New York Times bestselling account of the desperate hunt for a serial killer and his own investigation of California's unsolved Zodiac murders. A sexual sadist, the Zodiac killer took pleasure in torture and murder. His first victims were a teenage couple, stalked and shot dead in a lovers' lane. After another slaying, he sent his first mocking note to authorities, promising he would kill more. The official tally of his victims was six. He claimed thirty-seven dead. The real toll may have reached fifty. Robert Graysmith was on staff at the San Francisco Chronicle in 1969 when Zodiac first struck, triggering in the resolute reporter an unrelenting obsession with seeing the hooded killer brought to justice. In this gripping account of Zodiac's eleven-month reign of terror, Graysmith reveals hundreds of facts previously unreleased, including the complete text of the killer's letters.

"The New York Times" bestselling author who investigated the Zodiac case now uncovers a real-life mystery of murder, body doubles, and obsession. Marli Renfro was a model who played a part in one of the most iconic scenes in American movies - as Janet Leigh's nude body double in Alfred Hitchcock's "Psycho" - only to fade into obscurity, a footnote in Hollywood history. It wasn't until 1988 that Marli Renfro made news again - raped and murdered by a serial killer with a fetish for the classic Hitchcock shocker. But as Graysmith investigated Marli's story, a nagging doubt entered his mind. What if Marli was still alive? What if another woman had been murdered in her place? And if Marli was still alive, would he ever find her? The line between art and reality is blurred in this astonishing coda to one of the most memorable screen murders of all time, and to a real-life crime that one man was determined to solve.
