Lady Lupin, lover of cocktails, parties, and fast motor cars, finds herself married to a charming and thoughtful vicar. Unfortunately, his parish is located in an obsure and unimportant part of the country - to call it a backwater would be to flatter it.
Just as Lady Lupin is settling into her new home (complete with competative women heading up various girl guides, mother's assocation, you-name-it organizations), her husband's curate is killed.
Here enters the mystery. Unfortunately, it really isn't much of one. The majority of the book is about Lady Lupin and how she deals with other people, domestics, guests, misunderstandings, etc. All very interesting, sometimes charming, and sometimes amusing. But as far as the mystery goes, there is very little action on it after the curate is killed.
I'm not sure if I'm being clear, but this is one of those mysteries where the murder takes place, then there is a lot of interpersonal/character developement in the middle in the guise of sleuthing, and then the killer is unmasked at the end.
There is no slowly revealing and adding new clues along the way, no additional happenings (perhaps a second killing) to deepen the puzzle, really no puzzle, per se, at all.
