Query: "What in hell are German teeth?" asked Peter.

If that quote doesn't sound like Lord Peter to you, how about this quote from Lady Peter (Harriet Vane)? "About your second concern, however, I cannot be so emollient."There are really only two problems with this book: a weak plot and a tin ear for the way that Sayers' characters talk - as illustrated above. To be fair, there are some nice touches to the book. It's good to see the Bunters again, the background material on how WWII in England affected the daily life of the residents is excellent, and who can object to seeing Miss Twitterton finally married off - even if it is to an older Polish farmer.But the mystery is hardly mysterious. And the conversations between Lord and Lady Peter are painfully off key. Add a few improbable coincidences and some odd local color and the net result in not very satisfying, at least to this Sayers fan.
