Bill Granger is best known for his spy series, “The November Man.” But this versatile writer also wrote three mysteries about a former sports writer named Drover. Drover was involved in a messy gambling investigation. He was cleared, but his sports writing career was over. Drover found work as an investigator for a Las Vegas bookie. In the first book in the series, Drover (1991), Drover investigates the fixing of a NFL game: Denver Broncos vs. New Orleans Saints. In the second book, Drover and the Zebras (1992), Drover looks into a point-shaving scheme involving a nationally ranked college basketball team. And in Drover and the Designated Hitter (1994), Drover investigates betting on Major League Baseball games. If you’re a fan of sports mysteries, you’ll enjoy the Drover series.
