Nominated for the Man Booker Prize, an exquisite tale of romance and rivalry, gambling and greed, from one of England's finest writers   As the shadows lengthen over the June grass, all England is heading for Epsom Down—high life and low life, society beauties and Whitechapel street girls, bookmakers and gypsies, hawkers and thieves. Hopes are high, nerves are taut, hats are tossed in the air—this is Derby Day.   For months people have been waiting and plotting for this day. Everyone's eyes are on champion horse Tiberius, on whose performance half a dozen destinies depend. In this rich and exuberant novel, rife with the idioms of Victorian England, the mysteries pile high, propelling us toward the day of the great race, and we wait with bated breath as the story gallops to a finish that no one expects.
