On December 11, 1966, a shocking murder occurred in the small, working-class neighborhood of El Sereno, on the east side of L.A. In the middle of the night, a mysterious assassin viciously shot the nondescript, young Henry Stockton three times in the head and twice in the chest before setting his house on fire. Strangely, the murderer left behind no clues, and the police were baffled—until another murder occurred over a year later, when a young, pregnant woman was found bludgeoned to death in her Jaguar. In this true story filled with twists, criminal intrigues, and a dizzying string of circumstantial evidence, Vincent Bulgliosi—co-author of the best-selling Helter Skelter and prosecutor of Charles Manson—and Ken Hurwitz reveal how these seemingly unrelated cases turned out to be the work of criminal masterminds acting out of jealousy, greed, and desire to obtain affluence at any cost.
