The year is 1811. With the British army penned into a small part of Portugal, and all of Spain except for the coastal city of Cádiz fallen to the invader, the French appear to have won their war. Raised in the gutters of London and taught to fight, Captain Richard Sharpe is in the Spanish capital on a mission for the British ambassador. But when a British attack on an enemy-held bridge goes disastrously wrong, he finds himself trapped in a city under siege, a hotbed of treachery, false allies, and pernicious plots. And as dawn breaks on a March morning, Sharpe must be prepared to come to the aid of the charismatic Scotsman Sir Thomas Graham, the city's would-be liberator, whose small, outnumbered army has been abandoned by the Spanish and is now is caught between the devil and the deep blue sea. Yet for Richard Sharpe, the impending battle against overwhelming odds is about more than destiny and duty; it is about revenge.
