Odds Against, by Dick Francis
Former jockey Sid Halley has spent the last two years at a London detective agency, but is assigned only routine cases. After fourteen years as a steeplechase jockey, he’s restless and unhappy. On a simple assignment, he is shot in the gut and can’t eat solid food for a while. While he recovers, his father-in-law, Charles Roland, invites him for a visit, even though Sid and his wife Jenny are separated. Charles has borrowed an expensive gem and mineral collection and wants Sid to help him impress and investigate another guest, Howard Kraye. Kraye may be connected to a string of bad luck at nearby Seabury Racecourse. Sid learns that a developer wants to buy out Seabury’s shareholders and build houses on the land. At a visit to a stockbroker, Sid encounters secretary Zanna Martin, who hides an injury from the world, just as Sid does with his damaged hand. Thefts and explosions add to the suspense of this intricately plotted mystery, published in 1966. During an exciting pursuit behind the scenes at Seabury, Sid’s injured again, and his future at the detective agency is uncertain. I enjoyed the fast pace, well-developed characters, and some witty dialogue. Sid appears again in three more mysteries, and this book was made into a television series, The Racing Game.
