A Hercule Poirot Amuse-Bouche: Yellow Iris by Agatha Christie

What's better than a tale of twin poisonings like we had in our
last episode? Twin tales of twin poisonings, of course. This short
story is substantially similar to Sparkling Cyanide, which we just
covered, but it actually came first, and as a precursor to that
novel it also has some fascinating differences. Journey with us not
only to New York but--in the Suchet adaptation--to Argentina too as
we explore all that this Poirot story has to offer.
