<b>Jefferson Hinkley is back in the newest thriller in the Dick Francis tradition, this time on a special mission to the United States to investigate a conspiracy involving the biggest horse races in the country.</b><br> <br> Jeff Hinkley, investigator for the British Horseracing Authority, has been seconded to the US Federal Anti-Corruption in Sports Agency (FACSA) where he has been asked to find a mole in their organization - an informant who is passing on confidential information to those under suspicion in American racing. At the Kentucky Derby, Jeff joins the FACSA team in a raid on a horse trainer's barn at Churchill Downs, but the bust is a disaster, and someone ends up dead. Then, on the morning of the Derby itself, three of the most favored horses in the field fall sick. <br> <br> These suspicious events can be no coincidence. In search of answers, Jeff goes undercover as a groom on the backstretch at Belmont Park racetrack in New York. But he discovers far more than he was bargaining for: corrupt individuals who will stop at nothing - including murder - to capture the most elusive prize in world sport, the Triple Crown.
