The Black Moth (by Georgette Heyer)

(Amazon UK link)

This is a historical novel by Georgette Heyer.

'The Black Moth' is a particularly exciting and fast-moving story by one of my favourite authors. An Earl's son takes the blame for his brother's cheating at cards, and is forced to flee, eventually becoming a highwayman. He keeps his chivalry, however, and rescues a pretty girl, at risk to his own life.

Romance ensues (of course) and the climax includes a dramatic sword fight, before a cleverly written and very tidy ending that's typical of Georgette Heyer. 

Excellent.
