Sharpe's Sword: Richard Sharpe and the Salamanca Campaign, June and July 1812, Paperback/Bernard Cornwell

An unfinished duel, a midnight murder, and the treachery of a beautiful prostitute lead to the imprisonment of Sharpe. Caught in a web of political intrigue for which his military experience has left him fatally unprepared, Sharpe becomes a fugitive--a man hunted by both ally and enemy alike.
