I read Agatha Christie in huge gulps as a teenager. This is the first time I've revisited Hercule Poirot as an adult. Not much has changed; Christie is heavy on the intellectual exercise and light on characterization. Nigel Hawthorne does a good job with all the voices EXCEPT Poirot's, whose heavy accent is a bit ludicrous. The mystery was really easy. Ah well. Not her best.
