The widely praised and meticulously researched book that reveals the story of how, for fifty years, superlawyer Sidney Korshak and the nefarious Chicago Outfit pulled the strings of American business, politics, and society. Investigative reporter Gus Russo returns with his most explosive book yet, the remarkable story of the "Supermob"--a cadre of men who, over the course of decades, secretly influenced nearly every aspect of American society. Presenting startling, never-before-seen revelations about such famous members as Jules Stein, Joe Glaser, Ronald Reagan, Lew Wasserman, and John Jacob Factor--as well as infamous, low-profile members--Russo pulls the lid off of a half-century of criminal infiltration into American business, politics, and society. At the heart of it all is Sidney "The Fixer" Korshak, who from the 1940s until his death in the 1990s was not only the most powerful lawyer in the world, according to the FBI, but the enigmatic player behind countless twentieth century power mergers, political deals, and organized crime chicaneries.
