Old fashioned murder mystery very much in the Agatha Christie style. I enjoyed it very much. This was a free Amazon download.
We have a country house - very much comfortable living with an elderly husband, a very much younger wife. The party for the week end comprises his nephew and wife (broke and eye on the main chance as being inheritors), the wife's ex lover, another brother and sister - the brother couldn't care less attitude and out to create trouble wherever he goes and Angela Marchmont our detective very much like Miss Marple only decades younger.
The elderly rich man gets murdered and the who dun it starts with lots of apparent clues though for once I was fixed in my mind who the killer was (and I was right!)
Very countrified and I think typical of the time - both the attitudes of the young people and the old. Told in narrative form by Knox (he was the ex boyfriend by the way) which was a bit confusing as Angela was supposed to be the star turn. Nevertheless a very nice mystery murder for a lazy afternoon which I enjoyed very much.
I am only sorry that Ms. Benson has not written anymore novels!
