As an undercover FBI agent, Joe Pistone was able to infiltrate the American mob so convincingly, both the feds and Mafioso still express admiration for his work today, three decades after his descent into the Bonano family as up-and-coming hood Donnie Brasco.

    Mafia Summit: J. Edgar Hoover, the Kennedy Brothers, and the Meeting That Unmasked the Mob is the true story of how a small-town lawman in upstate New York busted a Cosa Nostra conference in 1957, exposing the Mafia to America. The book is by Gil Reavill.
