One of the best La Cosa Nostra book's I have read The Underboss details the rise and fall of Boston's most powerful Italian mobster, Gennaro "Jerry" Angiulo. Angiulo and his brothers controlled the city's gambling and loansharking rackets from their stronghold in the city's close-knit North End. Jerry Angiulo has to be one of the vilest creatures in the history of the American Mafia ruling with an iron-fist and continually berating his underlings which included calling his son Jason a "cocksucking motherfucker" to his face on regular basis for his constant mistakes. Angiulo was a multi-millionaire and huge money-maker for New England crime boss Raymond Patriarca, he wasn't considered a tough-guy but his power was backed up by the formidable Caporegime Larry Zannino, who along with Jerry's brother Danny, handled the murkier side of things gleefully murdering and maiming anyone who got in the Angiulo's way. The story details the FBI's attempts to bring down the Angiulo's by bugging their office on 98 Prince Street, no-mean feat in a neighbourhood constantly on the lookout for suspicious activity from law-enforcement. Through sheer hard work, resourcefulness and dedication the agents successfully bugged the inner sanctum of the Boston Mafia which proved to be a gold mine due to Jerry Angiulo's constant bragging and penchant for strategising out loud. He was brought to trial and convicted under the RICO act and sentenced to life in prison, with his brothers and underlings receiving varying sentences. This was one of the FBI's finest hours but unfortunately some of the agents who helped bring down LCN in Boston then compromised themselves by giving Irish Mob boss Whitey Bulger a license to kill while taking brides from the psychotic mobster in one of the darkest chapters in the history of law-enforcement. The Underboss is an incredible tale and I would highly recommend it, it's one of those books that you don't want to finish.
