After reading Whose Body? (the first Lord Peter Wimsey book) last year, I wanted to read more by Dorothy L. Sayers, so I chose Clouds of Witness (the second book) for my classic by a woman author. I actually finished it a few weeks ago, but I forgot to write my review for the challenge. Lord Peter Wimsey must figure out who killed the man who was engaged to his sister (Lady Mary) in order to save his brother (The Duke of Denver) who is accused of the murder. It was another enjoyable read and I rate it 4 out of 5.
