Accardo: The Genuine Godfather by William Roemer is a excellent book, i was partially fascinated by Murray Humphreys who was credited for inventing the term money laundering..
That was Roemer's best book, DeNiro. I still don't like the way he marketed "War of the Godfathers" as non-fiction, but I'll give him credit where credit is due with "Accardo." There was some great historical stuff pertaining to the City of Chicago in that book. But I really could have done without the way he kept referring to Accardo as "The Man." It got annoying after awhile. Still a good book, though.
