This is a big one! So big, we decided to break it into two parts. This episode deals with the novel only; next episode we will tackle the three English-language adaptations and also touch on the feature film yet to be released, which looms darkly on the horizon.... Our ranking of this one is bound to be a bit controversial, and we'd love to hear any strong opinions you may have. But first, go get your sponge bag, your handkerchief, your pocket watch, your pipe cleaner, your scarlet dressing gown, and of course your passport (no smudges, please) and climb aboard the Simplon-Orient Express with Papa Poirot for this undeniable Christie "crown jewel" of a novel.
