First, a confession. I have never cared much for Hercule Poirot. In this I am not alone, for his creator felt much the same way, describing him as a ‘detestable, bombastic, tiresome, egocentric little creep’, albeit a creep with remarkable commercial staying power. Fortunately, my prejudice doesn’t affect enjoyment of the brilliantly constructed plots and the unobtrusively effective storytelling.
