The Black Moth - Georgette Heyer

The year is 1752. Devil, the Duke of Andover, and highwayman Jack, the Earl of Wyncham are at odds over a country squire's beautiful daughter. Cheating at cards, the marital problems of the younger sister of the Duke and the younger brother of the Earl, and debts beyond imagination form the backdrop for this romance, Heyer's first work and the only one in the public domain.
