FAVOURITE AGATHA CHRISTIE NOVEL
I'm going to cheat a little bit here and choose three, because I can't decide between Marple and Poirot, and I also like her espionage tales.
Favourite Poirot - Murder on the Orient Express
Exotic locations, numerous red herrings, and Hercule Poirot - what's not to like?
Favourite Marple - 4:50 from Paddington
Cosy English setting and Jane Marple has a razor mind beneath that fluffy exterior.
Favourite espionage tale - Destination Unknown
Christie's take on the Cold War, with disappearing scientists, spies, and secret agents.
