The Body on the Beach: A Fethering Mystery

It's the classic British whodunit, set in a seaside town, with two elderly ladies taking on the role of the nosy private investigators. They are no Miss Marple, and I feel that this book didn't add anything new to the genre, so I probably won't read any of the others. But if this genre is your jam, then it's competently written, and you'll probably enjoy it.
