The Norwegian police have found no trace of him, nor have the British, and the case is being filed as just one more unsolved theft. David Cleveland, investigator for the Jockey Club, is a last resort. He goes without much expectation, and finds himself in waters as dark and deep as the fjords.

When a sick friend asks Edward Lincoln to investigate the comprehensive failure of a string of racehorses, he agrees to help out. But it is impossible for him to go about the task quietly and unnoticed because he is now a world-class star of action films, in which he always plays the hero.

On the first day of Royal Ascot, the crowd rejoices in a string of winning favorites. Ned Talbot has worked all his life as a bookmaker – taking over the family business from his grandfather – so he knows not to expect any sympathy from the punters as they count their winnings, and him his losses.
