Like so many other pretty butterflies, Indiana-born Vivian Gordon fluttered to New York in 1920 looking for fame and fortune. Before long, the flame-haired chorus girl parlayed her youth, beauty, and ambition into more profitable means as a tough and glamorous symbol of Prohibition-era excess. She was a speakeasy owner, blackmailer, high-end escort, extortionist, racketeer, and con woman. But given her dangerously intimate associations—from ruthless underworld gangsters to corrupt high-ranking city officials—Vivian was also a woman who knew too much and who rightfully feared for her life. On February 26, 1931, Vivian’s bludgeoned and garroted body was found dumped in Van Cortland Park in the Bronx. Now, in the first in-depth biography of its kind, Pulitzer Prize and Emmy Award-winning journalist Anthony M. DeStefano unravels her tumultuous life and the headline-making murder that became an obsession for many, including then-Governor Franklin Delano Roosevelt. The evidence Vivian left behind was damning: a diary with more than 300 names implicating powerful officials, philanthropists, businessmen, and every major gangland figure in collusion and corruption. The probe eventually resulted in the career-ending investigation of James “Jimmy” Walker, disgraced mayor of New York City. Ultimately, finally finds a place in history for Vivian, a woman with a rare legacy in gangster lore, whose demise was as tragically inevitable as the brutality of the city’s demimonde during Prohibition.
