The little-known third feature by the great French maverick Georges Franju (Eyes Without a Face, Judex) is a delightfully playful romp through Agatha Christie territory, whose script (written by Pierre Boileau and Thomas Narcejac of Les Diaboliques and Vertigo fame) is mischievously aware of the hoariest old murder-mystery clichés and gleefully exploits as many of them as possible. They’re equally aware of the detective story’s antecedents in the Gothic novel, a connection that Franju is only too happy to emphasise visually at every opportunity thanks to his magnificent main location. A young Jean-Louis Trintignant (The Conformist, Amour) is amongst the Kerloquen heirs. This blu-ray, DVD combo pack is loaded with bonus features.
