Hercule Poirot is perhaps Agatha Christie's most interesting and endearing character; short, round, and slightly comical, Poirot has a razor-sharp mind and puts unlimited trust in his "little grey cells." Those little cells come through for him every time, enabling Poirot to solve some of the most baffling mysteries ever conceived. In Death on the Nile , Poirot, on vacation in Africa, meets the rich, beautiful Linnet Doyle and her new husband, Simon. As usual, all is not as it seems between the newlyweds, and when Linnet is found murdered, Poirot must sort through a boatload of suspects to find the killer before he (or she) strikes again.
