On August 10, 1977, the NYPD arrested David Berkowitz for the Son of Sam murders that had terrorized New York City for over a year. Berkowitz confessed to shooting 16 people, and the case was officially closed. Spurred by clues overlooked in the investigation, journalist Maury Terry was convinced Berkowitz didn't act alone, but was linked to a Yonkers-based cult that was responsible for other ritual murders. This updated edition of his 1987 exposé includes an introduction by Josh Zeman, who used it as the basis for his documentary The Sons of Sam: A Descent Into Darkness.
