Jeff Hinkley works as an undercover investigator for the British Horseracing Authority. Mostly, it's just a case of exposing a horse-doping scandal or uncovering a few suspicious bets. But when the banned trainer Jeff's been following murders a bookie in cold blood right before his very eyes everything changes ... With both the police and Jeff's bosses demanding answers, the situation escalates rapidly. He soon learns that entire race meetings have been filled with drugged horses. Worse still, the perpetrator vows he will not stop until horseracing is ruined - unless he's paid a king's ransom. Jeff, using all his contacts and undercover skills, must discover who is behind it. On the line are his reputation and career - and soon his life.
