The Agatha Christie radio adaptations keep closer to the original stories than the more recent TV versions. John Mophet does an excellent Poirot; arrogant, but adorable from a distance. And Death on the Nile is one of Christie's best. Unlike other thrillers and mysteries, I listen to the dramatisations and audio books over and over again, even though I know the ending. What makes a Christie murder better than most others is that she sticks to what she's supposed to be doing -- spinning a good yarn. So many other writers distract you from the puzzle with sex, social issues etc. Modern crime writers could learn a lot from the Queen of Crime.
