After being disowned by her family, Cassandra Darcy – the artistic eldest daughter of Anne de Bourgh (and grand-daughter of the infamous Lady Catherine de Bourgh and Mr. Darcy’s cousin in Pride & Prejudice) – strives to make a living by painting. But struggling to succeed in bohemian London turns out to be the least of her worries! To begin with, there are the unwelcome advances of a certain Lord Usborne, introduced to Cassandra by a high-class procuress. Then there are the letters bequeathed to her by a friend – highly compromising letters written by his wife, Princess Caroline, that the Prince Regent would very much like to possess. In league with Lord Usborne, the prince enlists the services of Cassandra’s lawyer cousin, Horatio Darcy, to track down the missives. When Horatio’s investigation leads him straight to Cassandra, he is initially disapproving of her lifestyle until he finds himself utterly charmed by it – and particularly by her. Romance proves elusive, however, as social obstacles and the efforts of a vengeful Lord Usborne conspire to divide the two would-be lovers.
