4th of five ** FILE ** It was fifty-years ago when the Racehorse seen here at right, Devon Loch, owned by the Queen Mother Elizabeth is well clear of the field in the world's most grueling race, the Grand National steeplechase, at Aintree, England, on March 24, 1956, when he appears to jump a phantom fence 25-meters from the line and lands on his belly. The stricken Devon Loch gets back on his feet but is overtaken in the most dramatic final in the race's history and the jockey Dick Francis, walks away in despair. After clearing 30 jumps on the course the horse stumbled and fell just yards from the winning post, but now the jockey, Francis is a prolific fiction writer, and he owes his writing career to the downfall of his horse, according to his autobiography.
