On the morning of October 12, 1978, the Chelsea Hotel looked like it always did after a long New York night, with its hallways dim, its air heavy, and its secrets still clinging to the walls, but behind the door to Room 100, one of the most infamous mysteries in rock-and-roll history was waiting to be found. Inside, twenty-year-old Nancy Spungen lay bleeding on the bathroom floor, her life ended by a single stab wound, while just feet away, her boyfriend—Sex Pistols bassist Sid Vicious—stumbled through the room in a haze of drugs, shock, and confusion. What happened in those final hours would become more than a tabloid scandal or a punk-rock tragedy; it would become a case suspended somewhere between love story, crime scene, and cultural collapse, where every witness had a different version, every answer seemed to raise a darker question, and the truth, if anyone ever knew it, may have died inside that room.
