Compact well directed drama of the dawning realization of the Nazi threat in Europe. A noir before that was a popular genre. Walter Pidgeon handles his role well, his suave dignity enabling him to move from the lighter tone at the start of the film to the serious one later on. Joan Bennett is a breezy delight as a practitioner of the world's oldest profession although the Hayes office ludicrously insisted she have a sewing machine in the corner of her room to make it appear she's a seamstress. She did some of her best work in Lang films, he was a tough director but she was herself a straight shooter who had no problem giving as good as she got enabling them to work well together through four films.
