דיק פרנסיס

Under Orders is a novel by Dick Francis, published on 7 September 2006. This is the fourth Francis novel to feature Sid Halley, jockey turned private detective.

From the acclaimed master of mystery and suspense comes the story of a self-imposed outcast who must refresh his detection skills in order to save himself and his family.

A high-class, transcontinental horse-racing junket should be an idyllic getaway for the super-rich.But one passenger on this train is a sociopath, a genius at blackmail and criminal corruption—and he plans to take everyone for everything they've got.
