In the early 1980s, William Steel's life took a turn towards the macabre when he quite literally ran into Robert Durst in midtown Manhattan. Steel was attending a school for locksmithing and security systems at the time, and Durst -- the black sheep of a family that controls billions of dollars in New York real estate -- decided he could use a man of those specific talents. Little did Steel realize that his new acquaintance was not only the prime suspect in his first wife's mysterious disappearance but quite possibly the wealthiest serial killer in American history. For the better part of a decade, Steel and Durst maintained what has been called a friendship of mutual usury, as Durst paid Steel for use of his Brooklyn home to engage in drug- and fetish-fueled sex with a variety of prostitutes. As they got to know each other better, Durst boasted to Steel of darker deeds. Were they confessions of rape, torture and cold-blooded murder, or just the twisted fantasies of a maniacal multimillionaire? Steel didn't know for sure until years later. He's now convinced that Durst is, indeed, a murderous monster, and he remains haunted by thoughts that he should have done something to stop the fiend before he claimed more innocent lives. In his gripping memoir, Sex and the Serial Killer, My Bizarre Times with Robert Durst, Steel reveals the depths of the scion's depravity, and he demands justice for Durst's victims and their shattered families.
