Murder Must Advertise is such a fun book. Witty, word-play-y, though it works best if you’re already familiar with Lord Peter. Great characterisations, and not even that bad of a plot (always the weak point with Sayers). The characters were life-like and good and touching in unexpected places. Keen eye for British class and culture. Loved the banter, missed the Bunter. I’m very happy my re-read arrived here, because Murder Must Advertise and the next book, Nine Tailors, seem to me the best of Sayers’ work.
Edit: This review was written before I had read Gaudy Night, which I now consider her best work.
