The last Public Enemy No. 1 of the Depression era, Alvin "Creepy" Karpis reportedly compiled a record of fifty-four aliases, fifteen bank robberies, fourteen murders, three jailbreaks and two kidnappings.

His criminal career came to an end when J. Edgar Hoover and his famed G-Men apprehended the man they wanted more than any other in New Orleans. From there, Karpis found himself confined on Alcatraz Island, where he spent nearly twenty-six years - more than any inmate in the prison's history. Historian Julie Thompson tells the true story of Karpis's life and career, a riveting tale taking readers from rural Kansas and Ohio to the bustling streets of the Big Easy and into the bleak innards of "the Rock."
