First of all, I enjoyed middle-aged Dorothy Martin as crime solver. She's a well-drawn, likeable character whose words and actions match her persona. Second, Dams is a good writer with many fine word choices (salubrious, fulminating, and dissolute, for example.)
Third, Dams quotes great works of literature showing she has a broad reading background. This doesn't automatically make someone a good writer, but it sure helps. Fourth, the book shows a married couple in tune with each other's needs and interests, and I enjoyed their banter. Fifth, Dorothy and her husband are mentioned as attending church as if it were a completely normal, natural thing to do. Last, the book is filled with references to life in England which will appeal to anglophiles.
So why didn't I give this book more stars? Because it falls just short of being a cozy mystery; all three of the people involved in the crime were in some stage of sexual sin. No sordid details, though. The occasional light swearing and constant drinking might offend some.
Nevertheless, I look forward to exploring other Dorothy Martin mysteries.
