Simmons has written—sorry, I must adjust my grammar going forward. Simmons wrote in a wide variety of genres, including space opera, fantasy, historical fiction, science fiction, horror, and neo noir. Darwin's Blade is yet another: straight-forward action/thriller.
Front and center is Darwin Minor, a Vietnam vet who, after the war, has made a name for himself as the best accident reconstructionist in southern California. Running a private business, he uses knowledge of physics and the latest computing tools to help the police and victims identify what really happened at accident scenes. It's business as usual until somebody tries to kill Darwin as he drives home from an accident scene. Next thing he knows, a statewide investigation is underway for fraudsters staging accidents for insurance claims. That proves to be just the tip of the criminal iceberg.
