While J. Edgar Hoover was denying that there was such a thing as organized crime, in the forties, fifties, and sixties the mob was busy forming powerful syndicates in many northeastern cities. This book tells the fascinating, first-hand story of how FBI Special Agent Joe Griffin, with the help of a team of courageous professionals, succeeded through dogged determination and uncanny street smarts to convict major La Cosa Nostra leaders in Buffalo, Cleveland, Rochester, and Youngstown.Forget Hollywood's version of the mafia; this is the real inside story from a man who observed the day-by-day behavior of these "instinctual killers" and for whom "it was a matter of principle to destroy them." FBI Medal of Valor recipient Joe Griffin, with the help of writer/researcher Don DeNevi, provides intimate details of mob intrigue, drug deals, gambling rings, hits, bloody gangland wars, and even a plot to plant a "mole" in the Cleveland FBI office.All the more fascinating because it's true, Mob Nemesis is an engrossing story of the underworld from a man who took them on and won.
