I do less of that stuff now because I figured out that when I was writing things I didn't care about, it made me angry and depressed, so I turned my focus to what does make me happy, and also I recognized that one of the things that gives me great happiness is teaching creative writing, and so I could write profiles of professional golfers or I could be a professor. Being a professor made me much happier.

I'm really fascinated by how the mob ethos permeates places like Las Vegas and Chicago. I have the book set in Las Vegas and Chicago for pretty specific reasons, some of which are that in both cases the mob history has become a tourist attraction - I'm actually doing a book signing in Las Vegas at The Mob Museum, which I am positively giddy about! - and I find that especially unusual. If you don't call these people "the Mafia" they're just a band of psychopaths killing people for profoundly dumb reasons.

It's an unusual way to write a crime novel, to have these lingering, fairly large story points, but it's something I knew I had to do if I wanted to write a sequel...but, you know, people still have to read and enjoy this book, or it's a moot point.

I was aware that I had to pay off things in a convincing emotional fashion, that I had to address the lingering plot points in some real tangible sense, and that I had to make this a self-contained novel, in case I'm run over by a bus tomorrow or in case there's no demand for anyone to ever see a sequel. (Two things that I hope don't happen, incidentally.)

And there are rules for crime fiction. Or if not rules, at least expectations and you have to give the audience what it wants.

The fact is, though, what I think we really like is Marlon Brando, Al Pacino, Robert De Niro and James Gandolfini. We like what the media has created of the mob bosses in movies and TV and books, because it's something the average person never comes into contact with, it's almost as outwardly outlandish as a sexy vampire, and so we can romanticize it, it's non-threatening.

All of which is mostly bullshit. The reality is that it's just like any other Ponzi scheme: the guys at the top are doing pretty well, but the guys on the bottom are doing Amway pitches in trailer parks.
