Very entertaining book memoir with a former mafia assassin. The guy, in his 80s, ends the interview sessions by admitting to killing his friend, Jimmy Hoffa. He even goes into details about how he did it. Though that is the big news, he also hints that the mafia played a role in the Kennedy assassination. I don't know how I feel about his revelations, but it is, at the very least, an interesting look into the world that inspired The Godfather, Goodfellas, et al.
