SUMMARY: Considered to be one of Agatha Christie’s most controversial mysteries, The Murder of Roger Ackroyd breaks all the rules of traditional mystery writing. A widow’s suicide has stirred rumors of blackmail, and of a secret lover named Roger Ackroyd, who was found stabbed to death in his study. The case is so unconventional that not even crack detective Hercule Poirot has a clue as to how to solve it.
