In a battery of events that will make a hero out of an illiterate private, a young Richard Sharpe poses as the enemy to bring down a ruthless Indian dictator backed by fearsome French troops.The year is 1799, and Richard Sharpe is just beginning his military career. An inexperienced young private in His Majesty's service, Sharpe becomes part of an expedition to India to push the ruthless Tippoo of Mysore from his throne and drive out his French allies. To penetrate the Tippoo's city and make contact with a Scottish spy being held prisoner there, Sharpe has to pose as a deserter. Success will make him a sergeant, but failure will turn him over to the Tippoo's brutal executioners — or, worse — his man-eating tigers. Picking his way through an exotic and alien world. Sharpe realizes that one slip will mean disaster. And when the furious British assault on the city finally begins, Sharpe must take up arms against his true comrades to preserve his false identity, risking death at their hands in order to avoid detection and thus to foil the Tippoo's well-set trap.
