Magpie Murders

This was an impressive riddle inside a riddle mystery. It wasn't as cozy as some that I've read recently, and I didn't find myself feeling warm and fuzzy about the characters, but I was definitely hooked into the narrative and the twisty turns. There is something about a smart whodunnit (and this is very clever) to draw me in and keep my mind occupied -- something that is good for my mental health. I do recommend for that.
