Jefferson Hinkley is back. In his role as an undercover investigator for the British Horseracing Authority, Jeff is approached by the multi-time champion jockey, Dave Swinton, to discuss the delicate matter of purposefully losing races. Little did Jeff expect that this call would result in an attempt on his life. Dave Swinton is then found dead, burnt beyond recognition in his car at a deserted beauty spot. The police think it's a suicide but Jeff is not so sure. Hinkley starts to investigate but soon discovers that others are out to prevent him from doing so, at any cost.
