This week, have a bath and get your gray suit cleaned, it's time for the classic French thriller, Les Diaboliques!
This was a Carnage pick and is one of her all time favorite movies. As of this posting date, it's free to watch with Amazon Prime (you can rent it if you don't have Prime; it's cheaper here than other places we found).
If you don't want to watch first, be warned there are spoilers ahead! Also discussion and trivia!
