Agatha Christie is one of my favourite authors, and 'Death on the Nile' is one of my favourite books of hers! :) I'm glad you like it. Some of my other favourites are 'The Murder of Roger Ackroyd', 'Murder in Mesopotamia' and 'Murder at the Vicarage' (this one is a Miss Marple book). Definitely recommend you read any book written by her though :)
