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.
The old charters of Massachusetts, Virginia, and the Carolinas had given title to strips of territory extending from the Atlantic westward to the Pacific.
