Win, place, or show - Dick Francis

In Odds Against,
he lands a position with a detective agency. His first case brings him up against a field of thoroughbred criminals, and the odds against him are making it a long shot that he'll even survive.

Whip Hand finds Halley haunted by his glory days, although he still finds a certain satisfaction in solving a case. Hired by the wife of one of England's top racehorse trainers, Halley needs to figure out why her husband's most promising horses have been performing so poorly, and winds up haunted by more than just memories.

In Come to Grief, Halley becomes convinced that one of his closest friends-and one of the racing world's most beloved figures--is behind a series of shockingly violent acts. No one wants to believe that Ellis Quint could be guilty, so the public and press are turning their wrath against Halley instead. Now he's facing opposition at every turn-and finding danger lies straight ahead.
