In 1947, California's infamous Black Dahlia murder inspired the largest manhunt in Los Angeles history. Despite an unprecedented allocation of money and manpower, police investigators failed to identify the psychopath responsible for the sadistic murder and mutilation of beautiful twenty-two-year-old Elizabeth Short. Decades later, former LAPD homicide detective-turned-private investigator Steve Hodel launched his own investigation into the grisly unsolved crime -- and it led him to a shockingly unexpected perpetrator: Hodel's own father. A spellbinding tour de force of true-crime writing, this newly revised edition includes never-before-published forensic evidence, photos, and previously unreleased documents, definitively closing the case that has often been called "the most notorious unsolved murder of the twentieth century."
