Murder Must Advertise and The Nine Tailors and Whose Body are my rereads for Sayers since I really enjoy Parker and Mary. Though actually this reminds me that I want to reread Clouds of Witnesses as I love the Mary and Parker stuff but the whole brother plot while well written is uncomfortable. Also the one with the whole complicated inheritance one is interesting too. Harriet never really worked for me, I don't know why and so I tend to not reread books with her in them as much. Bunter is the best and really enjoying himself. I'd love to talk Sayers with you.

Have you read Ngaio Marsh since there are times she's clearly poking fun at the genre while writing it well?
