Sid Halley had been a champion jockey. But those days were lost in a fall beneath a 500-pound horse that cost him his left hand and his racing future — and fractured his marriage in the bargain.
Now medical and engineering science have provided him with a marvelous mechanical substitute for his whip hand. But there are no substitutes in Halley's life for his two great loves: his beautiful, bitchy ex-wife and thoroughbred racing.
And they're both in trouble — trouble that has led him into a battle of nerves with an elegant, vicious aristocrat, where losing could be worse than the loss of his hand, his career, or his wife — and where surviving means a desperate confrontation with his own worst fear.
