“Guilty conscience, eh?”
Filch is the embittered, unlovely, cantankerous old Hogwarts caretaker. Along with his beloved Mrs Norris, Filch patrols the school corridors looking for rule-breakers. Filch is a squib and deeply resents Hogwarts students for their magical abilities. In his downtime, Filch’s hobbies include oiling old torture instruments, writing lists of banned items and plotting the expulsion of Peeves.
