A muddled, boring, and unsatisfying whodunit. The detective and his partner are pale imitations of Holmes and Watson, and do little real detecting. I was a bit relieved to learn that Satyajit Ray was pressured into doing this movie (and that he also considers it his least satisfying), and that he had little say about the story. The camerawork is pretty good, and there's a somewhat noirish aura to the third act that's refreshing, but otherwise it's a dud.
