Agatha Christie is the owner of numerous superlatives: best-selling novelist, influential mystery writer, criminally successful playwright. Also, did we mention she's a dame?
Her novel, The Murder of Roger Ackroyd, written in the 1930s, endures not only for its fanciful cast of characters (including the lovable detective Hercule Poirot) but also for its subversion of the murder mystery genre. In short: read this one.
We spoil the heck out of this one's ending. Discussion of the book requires it. You've been warned!
