What is Miss Strangeworth's reputation in town?

Miss Strangeworth has a very good reputation in town. She's seen as a kindly, harmless little old lady. She often stops to talk to people in the street on her daily rounds, dispensing advice and generally making pleasant conversation. No one would ever suspect just how vicious and nasty she really is. After all, she's lived in the town longer than just about everyone else; her father was one of the first people to build a house in the street where she lives. And she's always seemed to care very deeply about the town and its inhabitants. Miss Strangeworth is a local institution.
The problem, however, is that Miss Strangeworth has become, in her own mind at least, the unofficial guardian of the town's stability and moral purity. This is her town, and she thinks that gives her the right to tell other people how to live their lives. And when she sits down in her quiet little study to write those nasty poison-pen letters, she genuinely thinks she's doing the town an important public service.
