Weran, the best source for what you're looking for is the book you were looking at in Barnes & Noble: "Donnie Brasco," by Joe Pistone. An excellent read, and even better than the movie (which was pretty good). Pistone also wrote "Way of the Wiseguy," a quick but pretty superficial read.
Ntra la porta tua lu sangu � sparsu, E nun me mporta si ce muoru accisu... E s'iddu muoru e vaju mparadisu Si nun ce truovo a ttia, mancu ce trasu.
