I'm unique for a suspense author in that I don't have a specialty background. A lot of suspense writers used to be lawyers or crime beat reporters. I didn't even know a cop when I started out. I finally figured out that I could visit prisons - I just had to be willing to make the phone calls.
Which reminds me of a fortune cookie: you often find your destiny on the path you take to avoid it.
I attacked Dawkins's book on God because I think he is theologically illiterate.
