Book excerpt: With individual thoroughbred racehorses costing millions of pounds each, the explosion in the bloodstock industry in the 1980s was the ultimate gamble of the decade - symbol of the business euphoria of the times. Tracing the events of how Sangster and his elite Irish racing experts took the world's most prestigious bloodstock auction, the Keeneland Sales in Kentucky, by storm and written with the co-operation of Sangster himself, this book is the inside track on a breathtaking bid to corner the thoroughbred market.
