Thinking more about the author, and what his knowledge of mafia is and whether or not he could have the insight that Puzo did; It is possible, because look at our Turnbull. He's not Italian, and I assume not mob connected
, yet look at all the knowledge he has on not only the mafia but Italian customs, traditions, etc.
It's not impossible that this author may have a handle on it as well. We can hope!
Of course, I really think TB should write the book, as I would have complete confidence that that it would be great as I am sure he'd put his heart and soul in it.
Since that's not likely, I'll hope for the best!!
