i think that Sarah Zettel aka Darcie Wilde aka Delia James can write good novels regardless of the genre and era.
I always enjoyed them and this book confirmed my opinion.
Rosalind is well developed, interesting and clever character. An unusual heroine who knows how to relate to the Ton and discover the culprits.
This was another well plotted and solid mystery that kept me guessing. Entertaining and gripping.
Highly recommended.
Many thanks to the publisher for this arc, all opinions are mine
