The Uberwald Incident
Samuel “Sam” Vimes is the Commander of the City Watch, the burgeoning police force of the Discworld’s largest city, Ankh-Morpork. His rise from drunk policeman to respected member of the aristocracy, and the simultaneous growth and development of the Watch under his command, have together been one of the major threads of the Discworld series. Born into poverty, (as a descendant of disgraced ancient Ankh-Morpork nobility), he is now a highly reluctant member of modern Ankh-Morpork nobility, having been made both a knight and a duke, as well as an ambassador.
Vimes is a very conflicted character: An incorruptible idealist with deep beliefs in justice and an abiding love of his city, he is also a committed cynic whose knowledge of human nature constantly reminds him how far off those ideals are. A member of the upper classes, he still has an innate dislike of hereditary wealth and a horror of social inequality. The conflict within Vimes is between his virtuous nature (“the Watchman”) and what he calls “the Beast”. Vimes protects himself from the Beast with the symbol of his own badge, which prevents him from becoming the criminal he despises, at least in his own mind.
