After Capone is the first book-length work to present the complete, never-before-told story of Frank "the Enforcer"Nitti—born Francesco Raffele Nitto—the driving force behind the Chicago mob's operations in the years that followed Al Capone's imprisonment. Beginning with Nitti's Italian origins, Mars Eghigian traces the Enforcer's entry into and subsequent rise inside Chicago's underworld, his near-fatal shooting by city detectives, his strange death, and the ultimate downfall of all who were associated with him.

Based on years of research and supported by original sources from state and federal archives, After Capone is the definitive reference on Nitti's violent life and times and a fascinating and chilling account of the ability of mob power to adapt to the constantly shifting nature of American culture.
