This is a biography of Robert Sangster, a man who forsook the comfortable life in a well-established family empire and with great daring embarked on a long-term gamble to transform a centuries-old British institution: horse-racing, and succeeded in revolutionizing the sport on a world-wide scale. The book reveals details of his associations with Vincent O'Brien, Lester Piggott and Pat Eddery. It tells how Sangster challenged the system and replaced it with his own, turning a sport into a multi-million-dollar commodity market - one where the inch of a short-head defeat can mean a difference of #10 million. The author's previous books include Lester Piggott: Downfall of a Legend.
