Sid Halley, former British jump racing champion and private detective, is not having a good time. His wife Marina has decided she needs some time out of their marriage to think about the future and Sid is devastated. But then Gary Bremner, an ex-jockey trainer, calls him to ask for his help - he is being threatened by someone in the racing world and he needs a friend he can trust. However, the very next morning, Gary’s stable yard is torched, horses killed, and Gary has disappeared.

Determined to uncover the truth and to help his friend, Sid starts to investigate. He soon finds himself embroiled in a conspiracy that cuts to the very heart of the integrity of British horse racing, and then danger comes closer to home than ever.

Can Sid get to the bottom of what’s going on before he too becomes a victim, while, at the same time, saving his marriage?
