And Then There Were 55: Peril at End House by Agatha Christie

There is so much to cover in this devilishly clever and somewhat
underrated Poirot mystery. (Plus cocaine. A lot of cocaine.) Join
us as we discuss just how bad a job M. Poirot does in this one
(it's surprising!), the finer points of Art Deco design, and the
delightfulness of Cornwall as a setting (though sadly, sans
Poldark).
