The summary of "The Rocking-Horse Winner" is the following:
Hester is dissatisfied with her life because she has no luck and her husband does not make as much money as she would like. Her son Paul begins to place bets on horse races together with his uncle and the gardener, and the horses he chooses actually win. He and his uncle decide to give his mother a gift of five thousand pounds, but he becomes ill. The day of the Derby he wins eighty thousand pounds, and he confesses his mother that he can guess the name of the winner horse by riding his rocking horse at home and reaching a psychic state of mind. Finally, he dies that night, and Hester feels that he is doing better now that he is dead than riding a rocking-horse in order to make money.
