Jockey Kit Fielding's patron, Princess Casilia, is in trouble. Her invalid husband is being threatened by a ruthless business partner who wants to use the firm to manufacture arms. At the same time, some of the Princess's best horses are being killed - shot by a bolt.
The only person the Princess can turn to is Kit - but he has problems of his own. His fiance Danielle has taken a shine to another man. And his old feud with Maynard Allardeck, racing steward and hereditary enemy of the Fieldings, might lose him his license to race.
Between riding winners (and trying to save his impending marriage) Kit has somehow to find out and stop who is slaughtering the horses. But, as he's about to discover, the killer has more than horses in his sights . . .
