Unnatural Death - Dorothy L. Sayers

Miss Climpson´s letters to Lord Peter are a hoot:

 

This Miss Clara was evidently rather a "character", as my dear father used to call it. In her day she was considered very "advanced" and not quite nice (!) because she refused several good offers, cut her hair SHORT (!!) and set up in business for herself as a HORSE-BREEDER!!! Of course, nowadays, nobody would would think anything of it, but then the old lady - or young lady as she was when she embarked on this revolutionary proceeding - was quite a PIONEER.

 

I totally adore her writing-style.
