Sharpe's job as Captain of the Light Company is under threat and he has made a new enemy, a Portuguese criminal known as Ferragus. Discarded by his regiment, Sharpe wages a private war against Ferragus - a war fought through the burning, pillaged streets of Coimbra, Portugal's ancient university city.

Sharpe's Escape begins on the great, gaunt ridge of Bussaco where a joint British and Portuguese army meets the overwhelming strength of Marshall Massena's crack troops. It finishes at Torres Vedras where the French hopes of occupying Portugal quickly die.
