"One Good Turn (A Jolly Murder Mystery)" by Kate Atkinson
This is Atkinson's second foray into the murder mystery realm...very much tongue in cheek I think. I quite liked her first novel "Behind the Scenes at the Museum"(not a mystery) which was quite funny and a little strange. I tried "Emotionally Weird" but found it a little too weird for my taste. One Good Turn is quite amusing (first half better than the second) but if you're looking for a mystery that's quite well written and has some substance give it a try.
