Thanks for the tip, Hal! I’ll definitely have to look for Douglas Wilson’s book, as well as Josephine Tey. I always keep an eye out for new mystery writers. I can only reread Death on the Nile or Gaudy Night so many times…
You should check out Michael Innes‘ mysteries. He’s a Scottish novelist and academic. (In addition to some great mysteries, he wrote a lot of literary criticisms. I love his work, but I always feel rather stupid after reading it–I have to stop frequently to look up definitions or track down his many allusions!
I also enjoy Catherine Aird, mostly as a mental break. It’s light reading, but very entertaining.
