A Hercule Poirot Amuse-Bouche: The Affair at the Victory Ball by Agatha Christie

How have we not covered Christie’s first published short story
yet?! (A Poirot, naturally.) Consider this a master class in some
of the fundamental tropes she would go on to use many, many times.
Actors, costumes, a temporal deception, even the harlequinade! Add
to that a real-world, “ripped-from-the-headlines” analogue, and
what more could two Christie podcasters want? (Well, we could
always use more Miss Lemon in the Suchet adaptation, but we can't
have everything.)
