Suspense movies are seldom as fun as Henri-Georges Clouzot's Diabolique. While many psychological thrillers get bogged down in the morose mental unravelling of their protagonists, Clouzot adopts a more playful technique. A very cruel man is murdered by his wife and mistress; pretty simple so far. But, soon, the body goes missing and the two women slowly come apart. A story like this could seem like the stuff of particularly dark horror stories, but our able director has the audacity to make the audience enjoy it. We squirm right along with these characters, knowing that there is something more than meets the eye here, but never quite knowing what. Like the best Hitchcock combined with the best Agatha Christie, Diabolique presents us with a grotesque tale, following it with a quick, almost-indiscernible wink, just to let us know that it will always be two steps ahead of us.
