Sid Halley, champion steeplechase jockey, suffers a devastating injury in a fall that ends his career. He sinks into self-pity until his aristocratic father-in-law bullies him into trying something new: becoming a private detective. A great literary gumshoe emerges as Halley regains his dignity, faces his vulnerability, and finds new meaning in life.

Based on the novel Odds Against and other stories by former jockey and bestselling author Dick Francis, this series goes inside the cutthroat world of British horse racing. As owners scheme, bookies connive, and greed leads to murder, Halley uses what he learned as a jockey to expose the scoundrels in the Sport of Kings.
