Sammy "The Bull" Gravano was one of the most feared mobsters in history. As the right-hand man to mafia kingpin John Gotti, he carried out multiple murders on behalf of the crime family. But after his arrest, he committed the ultimate mafia sin: he broke the sacred oath of silence and cut a deal with the government—agreeing to testify against his former boss. In shocking testimony, Gravano described the cold-blooded murders of close friends and business partners and the secret world of La Cosa Nostra. As the highest-ranking mobster ever to defect, The Bull's testimony helped put Gotti and dozens of others behind bars and devastated the hierarchy of organized crime. After the trial, Gravano was supposed to slip away quietly under the Witness Protection Program with a new name and a new face. But the notorious gangster was not about to live a normal life. Despite the bounty on his head, Gravano abandoned the Witness Protection Program and drifted back into the criminal world. Sammy Gravano is one of the last mobsters of a bygone era and his journey from Bensonhurst, Brooklyn to the mafia's inner circle, to government informant, and then to prison, is a riveting tale of murder, betrayal, and survival.
