In the second episode of this absorbing series with those who lead or seek to lead US horseracing during its most critical battle of ideas, Nick talks to the US Jockey Club Chairman Stuart Janney III. A scion of one of racing's most important dynasties, Janney has divided opinion sharply through his stewardship of its most august institution, particularly through his trenchant views on doping in the sport and his recent appearance on 60 minutes. Here, he gives Nick the unvarnished story of how he set about rooting out the most notorious dopers in US racing history with the help of private investigators. This, and much more:
