Outside chance - Lyndon Stacey

Ben Copperfield is a freelance journalist who specialises in all things equine, so when he is called with the news that the hot favourite for the Cheltenham Gold Cup has been kidnapped, just a few weeks before the race, he wastes no time in following the story up. This could be the racing scoop of a lifetime.
But as the date of the Gold Cup draws ever closer, it is unclear whether the missing horse is still alive. Where could a valuable racehorse be hidden for so long? And what is the secret from the owner's past that he is keeping from the police? Doggedly chasing the truth, Ben finds himself tested, both physically and psychologically, as he gradually uncovers a tale of prejudice, ambition and heartbreak.
