More than fifty years after what has been called “the most notorious unsolved murder of the 20th century,” the case has finally been solved. On January 15, 1947, the body of beautiful 22-year-old Elizabeth Short—dubbed the Black Dahlia because of her black clothing and the dahlia she wore in her hair—was discovered on a vacant lot in downtown Los Angeles, her body surgically bisected, horribly mutilated, and posed as if for display. Even the most hardened homicide detectives were shocked and sickened by the sadistic murder. Thus began the largest manhunt in LA history. For weeks the killer taunted the police—and public—much as his infamous English counterpart Jack the Ripper had done in London 60 years before, sending tantalizing notes, urging them to “catch me if you can.” And for weeks and months the LAPD came up empty. Charges of police ineptitude soon gave way to rumors of corruption and cover-up at the highest levels. Meanwhile, a rash of lone women in LA were brutally murdered, and their cases also remained mysteriously unsolved. Could the Black Dahlia Avenger be, in fact, a serial killer stalking the city streets?
