A fair-haired and uniformed member of the City Watch or police force, Angua is first seen in Commander Vimes' office, lurking in the shadows. He witnesses the protagonist William de Worde being dressed down about causing trouble by what he publishes in the Ankh-Morpork Times. William has seen Angua on the streets and finds that she stares at people too intently. Her face goes blank when William guesses that Cpl. Nobbs is a werewolf. She is herself quite important in the werewolf community and able to keep strangers from finding the Patrician's lost dog, Wuffles. She is put on William's track along with Watch gargoyles, but William buys a particularly stinky concoction of oils of aniseed, rampion, and scallatine and hurls the scent bomb beneath her nose, incapacitating her sense of smell. She likens it to running unprepared into Foul Ole Ron. It shuts her nose down for hours. The Watch cannot arrest William for assaulting an officer because Angua is in werewolf form at the time and they do not want her true nature to become public knowledge.
