A successful steeplechase jockey, Francis turned to writing after he retired from racing in 1957. He penned 42 novels, many of which featured racing as a theme. His books were translated into more than 20 languages, and in 2000 Queen Elizabeth II — whose mother was among his many readers — honored Francis by making him a Commander of the British Empire.
Francis' son Felix said he and his brother, Merrick, were "devastated" by their father's death, but "rejoice in having been the sons of such an extraordinary man."
