Lord Waincliffe breaks his horse’s bridle out riding one day and calls at the nearest house for help so that he can ride home safely. It belongs to Terence Stourton, a Professor of Literature, and he meets his daughter, Rosetta, who repairs the bridle for him. Not only does he think that Rosetta is the most beautiful girl he has ever seen, but he feels there is something unusual about her. Only when he returns home does he realise that she bears an extraordinary resemblance to his sister, Dolina. Lord Waincliffe and his brother, Henry, are finding it very difficult to afford their house and estate and they have the idea that the Marquis of Millbrook, who livesnearby and is very rich, could help them build a Racecourse on both their estates that would solve all their financial woes. So they invite the Marquis, who is known for his love of beautiful women, and they expect their lovely sister to help them persuade him, but Dolina insists on going to London for a ball instead. They enlist Rosetta to impersonate Dolina for the evening and the Marquis is so deeply impressed by her and her beauty that he agrees to fund the Racecourse. Then the problems for Rosetta really begin and when all seems impossible and her heart is forever broken, everything is resolved in this fascinating and intriguing tale by BARBARA CARTLAND.
