Jim --
You're way ahead of me. I'm hoping this will be a series, but the idea is for sports-related thrillers, not just golf. The next one is about baseball. If given the chance, though, I'll definitely write another golf thriller before I base one on soccer or tennis.
Mike -- Even Dan has this one wrong. The original detective character was a golf course rater who couldn't afford his travel expenses and decided he needed to supplement his income by solving crimes in the exotic locales he visited, such as Agar, South Dakota and Valentine, Nebraska. It was going to be a "Route 66" kind of deal, but I'd put the guy in, say, Holyoke, Colorado, and nothing would happen, except that he kept running into Matt Ward. This, of course, provided the opportunity for dark farce, but it wasn't good thriller fodder.
