William Powell stars as detective Philo Vance in this suspenseful locked-room murder mystery. Along with a lot of head-scratching clues, there's plenty of fun stuff about stuffy art collectors, a beautiful debutante trapped in a house of hate, a glamorous stage star keeping a tryst with a "dead" man, a walking corpse, and a wounded dog that knows the answer to the most inexplicable mystery ever tackled by the most captivating sleuth since Sherlock Holmes! Oscar winning Director Michael Curtiz (Casablanca) spins a tale that is absolutely guess-proof!
