I like a good “cozy,” but it needs to be either one of the British classics (Agatha Christie, Ngaio Marsh, Margery Allingham, the immortal Dorothy Sayers), Rex Stout or a well-plotted and character-driven recent addition. I’m especially fond of Donna Leon’s series set in Venice, and the attention her Guido Brunetti pays to meals and to his former-radical wife. There are a lot of bad mystery novels out there–anything involving a recipe, a quaint/creepy nonexistent village or someone with a peculiar name is instantly suspect to me.
The big question is, why are mystery novels a satisfying small comfort? What do they do that romance novels, for example, do not? What need do they fill? I think mystery novels work for those of us who love them because they create a small world, people it with characters you can believe in, ask a question (who killed Roger Ackroyd?) and answer it in a logical and emotionally satisfying way. In most cases, the guilty are punished and the innocent released.
Some mystery novelists are able to make readers comfortable even when good does not prevail. Donna Leon’s novels have an extra twist; sometimes the evil are not punished due to the depravities of the Italian government and its corruption. The “Aurelio Zen” novels feature this as well.
Why is mystery more rewarding than romance? I’m not sure if it’s because some of us need logic, and others just don’t believe in Prince Charming any more. Maybe it’s just the pleasure of being lost in a complete, well-formed world with characters you care about, and mortal results. Maybe it’s that these books have order, in a world of disorder. What do you think?

I’m so glad you include Margery Allingham in your comments about the appeal of Murder Mysteries. As a life-long writer she was deeply interested in her own craft and made many perceptive comments about this. I learned so much from her when I was writing her biography, The Adventures of Margery Allingham (ISBN 9781899262014) and I would willingly send you a copy of this if you would find it interesting. You’d need to send me an email with some details. Happy reading anyway (Have you tried Imogen Robertson yet – new young British author of historical murder mysteries)
Thanks, Julia. I’ll get with you about your biography of Margery Allingham. Haven’t tried Imogen Robertson yet — thanks for the tip! I have been reading the “Shardlake” series by Robert Sansome.
Mmmm I really enjoyed the first two but found Sovereign just too long and bulky. Haven’t been back but perhaps I should. What did you think of the later ones?
Just started Sovereign. We’ll see!
Quick correction–author’s name is C. J. Sansom, in case anyone is looking for the books.
