Dick Francis: The Edge

From the Publisher:
Undercover operative Tor Kelsey just received his make-or-break assignment: masquerading as a waiter on The Great Transcontinental Mystery Race Train - a high-class horse-racing junket for the super-rich. He was told to look out for trouble, but he never could have guessed how much.

Because one of the passengers on this elegant excursion is Julius Apollo Filmer - a sociopathic genius of blackmail and criminal corruption. His goal - take the train and its passengers for everything they have. And Tor is the only one with enough cunning and courage to take him on...
