Books like False Colours by Georgette Heyer

After the Countess of Denville dies, her husband’s debts threaten the family’s status. Resourceful twins Evelyn and Christopher Fancot must steer the Denvilles through financial peril and intertwined romantic entanglements. The younger brother, Christopher, discovers his missing twin, Evelyn, the new Earl of Denville, has vanished. To protect their mother’s reputation and preserve a promising marriage for Cressida Stavely, Christopher impersonates his twin at a high‑society engagement. While concealing his identity, Christopher faces demanding relatives—including the strict Lord Brumby, the shrewd Sir Bonamy Ripple, and the formidable Lady Stavely—and navigates the complexities of court life. His cleverness and charm gradually change Cressida’s feelings, revealing deeper connection and truth behind the family’s financial crisis.
