This character is the villain of the story, and though the narrator describes him as a killer, the term "evil" is not inaccurate in describing this man. Leroux is on special assignment from Napoleon, and his task involves the abduction and torture of civilians in his search for a spy who damages the French cause. Not merely satisfied to get the information from torture, Leroux also carves his name in his victims so that others will fear him. He presents a formidable opponent for Sharpe. Leroux is cunning and deadly with his sword, the most finely crafted sword Sharpe has ever seen.
