Genovese, Gambino, Bonnano, Colombo, and Lucchese. For decades these Five Families ruled New York and built the American Mafia (or Cosa Nostra) into an underworld empire. Today, the Mafia is an endangered species, battered and beleaguered by aggressive investigators, incompetent leadership, betrayals, and generational changes that produced violent, unreliable leaders and recruits.

From his heyday to the present moment, Al Capone - Public Enemy Number One - has gripped popular imagination. Rising from humble Brooklyn roots, Capone went on to become the most infamous gangster in American history. At the height of Prohibition, his multimillion-dollar Chicago bootlegging, prostitution, and gambling operation dominated the organized-crime scene.

Vincent "Chin" Gigante. He started out as a professional boxer - until he found his true calling as a ruthless contract killer. His doting mother's pet name for the boy evolved into his famous alias, "Chin", a nickname that struck fear throughout organized crime as he routinely ordered the murders of mobsters who violated the Mafia code. Vincent Gigante was hand-picked by Vito Genovese to run the Genovese Family when Vito was sent to prison. Chin raked in more than $100 million for the Genovese Family, all while evading federal investigators.

Drawing on a trove of sealed files and previously classified material, Whitey digs deep into the mind of James J. "Whitey" Bulger, the crime boss and killer who brought the FBI to its knees. He is an American original - a psychopath who fostered a following with a frightening mix of terror, deadly intimidation, and the deft touch of a politician who often helped a family in need meet their monthly rent. But the history shows that despite the early false myths portraying him as a Robin Hood figure, Whitey was a supreme narcissist, and everything was always about him.

For decades the FBI let James ''Whitey'' Bulger get away with murder, allowing him continued control of his criminal enterprise in exchange for information. He went on the lam in 1995, after the terrorist attacks of 9/11, 2011 followed top-ranked Osama bin Laden on the FBI'''s Ten Most Wanted List, and then was captured in Santa Monica, California weeks after Bin Laden's demise.
