I have to admit that I haven't read much of Agatha Christie's work. I know I've read Murder on the Orient Express and that I've listened to a few others on audio, but I really haven't made a dent. She was quite prolific after all.
While driving today I heard an interview with actor David Suchet on Talk of the Nation (NPR). Suchet has played Agatha Christie's most famous sleuth, the eccentric Hercule Poirot, in the aptly named British television series Agatha Christie's Poirot since 1989. Hearing Suchet talk about Poirot and the challenges inherent in bringing the character to life made me want to read more of Christie's work.
