Francis and Welcome bring readers another richly entertaining collection of the best horse-racing stories by authors past and present. Here are selections from Damon Runyon, Molly Keane, Banjo Patterson, and others, as well as one selection each from Francis and Welcome.  In "My First Winter," John Welcome's narrator describes how he was hoodwinked by his best friend into riding a horse for him in a comical steeplechase. And in "Spring Fever," Dick Francis unfolds the tale of the fiftyish widow, Mrs. Angela Hart, who is entirely too trusting of her conniving trainer and jockey, until a chance hint alerts her to their deception and gives her the opportunity for revenge.
