Really interesting. Took me a little time to get into the story, and the end, when it came, seemed rather abrupt. I found the mystery itself quite fascinating, and not a tame as I'd expected. I appreciated the way the author hinted and suggested the really gruesome bits without having the be really explicit. There were a couple of passages in the book written in second person; a literary device don't recall having ever encountered previously. I was familiar with the concept, but I never really understood how it might work. I found it very effective.
Ian Carmichael does a wonderful job of reading the book. I did find some of the early conversations between Wimsey and Parker a bit confusing as I was having trouble distinguishing who said what, but that problem seemed to fix itself.
