In the early stages of her career, Agatha Christie was known for writing engaging whodunits full of lively characters and utterly madcap plot twists. As she matured as a writer, however, Dame Agatha became less interested in zany new ways to kill the dead bodies, and more interested in pursuing heady philosophical investigations about the nature of justice. Many of the stories from her middle period have barely any mystery to them at all; the cast is so small and the events so clear that the focus becomes less on trying to figure out who the killer is and more on investigating the killer’s motivation and that of the detective exposing the truth — as often as not that indefatigable Belgian, Hercule Poirot.
All of which brings us to Curtain. Written at the peak of Dame Agatha’s career (though not published until the end), Curtain opposes Poirot with a villain who is utterly and unapologetically evil, who commits heinous crimes for the sheer pleasure of it, who cannot be dissuaded, and whose crimes, by their very nature, are beyond the reach of the law. If you’ve never read Curtain, beware the rest of this post, as it will be filled with spoilers. If you have, however (or if you don’t care), read on as we explore what Dame Agatha had to teach us about the relationship of justice, the non-aggression principle, and morality.
