I thought this was a very exciting Christie novel. This is one of Agatha Christie's favorite books because of the psychological insights Poirot employed in solving the murder of a young, beautiful, wealthy bride. Before Poirot could clearly see who committed the murder, he had to sort out the other criminals who had gathered on a sightseeing trip up the Nile River. There was a thief, a terrorist, a kleptomaniac, a blackmailer, and a stalker along with an alcoholic, a Communist, an English attorney and untrustworthy American trustee. Poirot deftly sorts out the different crimes, leaving the reader stunned at the close of the book. I highly recommend this book for someone who hasn't yet read a Christie book and needs a powerful introduction to her novels.
