A Special SUMMER HOLIDAY Hercule Poirot Amuse-Bouche: Problem at Sea by Agatha Christie

The real mystery of this very special episode is why Hercule "mal
de mer" Poirot would choose to spend his summer holiday in a boat
on the Mediterranean, but luckily for us he does, along with a cast
of characters running the full spectrum of companionability from
delightful to despicable.... So come soak in the sun with us as we
explore Poirot's most extreme--and perhaps, ironically,
darkest--solution of extralegal justice among his many, many cases.
