With tight breeches and loose morals, the horse trials circuit is a hell-for-leather chase across the magnificent parkland of England's finest country estates. Flirtation is compulsory sport; love is a professional hazard. Silver-tongued charmer Rory Midwinter is quite at home in this hedge-jumping, bed-hopping world of competitive weekend house parties. Having been born into the saddle, and with a rock star owner as patron, he has no intention of settling down. Only his long-term groom Faith has other ideas. Tash and Hugo Beauchamp are the undisputed golden couple of British three-day eventing, but their mettle is put to the test by the arrival of The Devil on Horseback, brooding Kiwi rider, Lough Strachan. Lough holds the key to Hugo's darkest secret, and he intends to use it to access his greatest rival's beautiful wife.
