Horse racing can be a dangerous sport, but it becomes a deadly one when a champion is killed. As he rode through the thick English fog, jockey Alan York was looking at an all-too-familiar sight: the back of champion rider Bill Davidson astride the great racehorse Admiral. But this was one race York was destined to win. Before Admiral jumped the last fence, Bill Davidson would be dead. Alan knew racing was a dangerous sport: horses fell, jockeys got hurt. But he also knew this had been no accident. It was the kind of knowledge that could get a man killed.
