Yes I definately agree. But the main problem with reading Donnie Brasco is the fact that theres always another undercover agent he has to introduce and it just seems dodgy. I'm suprised Brasco was never under much supervision from the wiseguys. Don't get me wrong though it is interesting seeing the cases interlocking though.

You right aswell about Sonny you really do bond with him more in the book and Leftys devotion towards Brasco is amazing.
