A gorgeous film noir from Denmark. It’s as stylish, atmospheric and bleak as any of its American or French counterparts (the true Scandinavian speciality is the constant boozing and problematisation of alcohol consume). Although the culprit is obvious from quite early on, “Mordets Melodi” plays with the viewer’s expectations and beliefs (perhaps even making fun of them), thus managing to keep up the suspense.
The most extraordinary of this unexpected noir coming from Denmark is that while he kills his victims, the killer sings imitating the voice of the film's false guilty, ie, he personifies from inside something that Hitchcock's Norman Bates would make as a factor from outward signs: a personality's transvestism, that De Palma would make seminal. That and an astonishing mastery of light and shadows in certain sequences.
