This is one of the most complicated murder cases ever screened, the story is overwhelming in complexities, and what seems to be an easy and self-evident beginning, soon winds itself into an inextricable labyrinth, in which everyone is misled to gross mistakes except the one man who knows and maybe is responsible for it all, the mysterious character of Doktor Warschauer, a pathetic remnant of a once brilliant ace of culture, theatre and learning, reduced to a hopeless remorseful drunk, who doesn't care about anything any more but who is the only one who knows the entire truth although he has perjured himself for it, and he prroduces the very weird definition of justice in the most famous scene of the film, when he confides in his young student (learning English from him) in Lucerne with two ballerinas dancing gaily in the background - a typical Julien Duvivier grotesque but ingenious arrangement. Because of one victim, they are all victims in this, and although there might be some hope after all, the hoplelessly desperate face of Mr Maurizius in tears vanishing in the darkness is the final signature of the film. This is perhaps Anton Walbrook's most interesting and prominent performance, seconded well by the totally matter-of-fact and unsentimental Charles Vanel in his most consistently objective role - his poker face conceals any abysses of regrets and hard experience, maybe also of intolerable lessons, but he lets absolutely nothing out. Eleonora Rossi Drago plays the most important female part, and although her part is small, she turns the tables more than once. It's an excruciating labyrinthal odyssey in the hopeless Kafkaesque nightmare of the entrapment of court procedures, (the author Jacob Wassermann of Vienna, 1873-1934, was himself a Jew,) but Julien Duvivier as usual controls everything with the accomplished hand of a perfect master.
