Series: Edwardian Murder Mysteries #1
This is an Edwardian mystery with a naïve young woman called Rose and a slightly older gentleman with a war wound as amateur detectives when a woman is found dead at a country house party. The period information was sometimes over-explained, Rose was incredibly naïve, and the mystery was so-so with a lot of cover-ups because of the suspects' positions in society. It took a while to get to the death too because there was a lot of introduction with Rose and Harry before we got to the party. Not sure whether I'll read another one in the series.
I liked the narrator though.
