A good read, IMO of an authentic mafioso. I read the paperback when it came out in the early 70s and "The Godfather" was the buzz, and "Joey" did a memorable review of that film and fictional mob family. I also liked Joey's hardcore honesty when it came to his personal thoughts on doing his job ("like a guy lays brick"). Intensely sociopathic, as you'd expect.
The only thing I take exception to is in the book's description/teaser: "...includes an afterword by coauthor David Fisher that unmasks Joey’s real identity..." is only true in a very general sense. No names are named, so "Joey Black" is still the only name we know him by.
