In this true crime history, a Chicago cop uncovers the epic gangland saga that led to a former bootlegger’s assassination in 1959.
 
When beat cop Don Herion and his partner responded to shots fired on December 16, 1959, they didn't know that they had heard the final, fatal salvo in one of the most contorted conflicts in the history of organized crime. Back in the 1930s, bootlegger and Irish mob boss Roger Touhy went to war with Al Capone and his Chicago Outfit. Then he was framed for a fake kidnapping. After twenty-six years in prison, Touhy was finally released. Less than a month later, he was murdered in an ambush. 
 
Touhy’s epic story of crime and punishment involves nearly all the notorious men of his day: Frank Nitti, John "Jake the Barber" Factor, Mayor Cermak, Melvin Purvis, J. Edgar Hoover, Baby Face Nelson, Dan "Tubbo" Gilbert, FDR and JFK. As Touhy's life was ending on his sister's front porch, Herion's quest to unravel the tangle of events that led to his assassination had just begun.
