There are four crucial scenes in this film where Hitchcock shows a change in perspective and identity through mise-en-scene. Hitchcock's characteristic motifs, style and themes are conveyed through the mise-en-scène. There are three key scenes that best exemplify Hitchcock's technical proficiency. After Alicia's party and encounter with the police, she is shown lying in bed with a hangover. We see a close-up of a concoction Devlin made for Alicia's hangover. The next shot is a Dutch angle of Devlin, with his arms crossed and in shadow. Alicia drinks more of the mixture and the camera perspective is in Alicia's point of view. The right-leaning Dutch angle rotates clockwise to an upside-down shot of Devlin as Alicia is lying upside down on the bed. Coincidentally, after the elaborate camera work, Alicia sits down and says, “What is this about? What is your point of view?”. Hitchcock's technical proficiency in this scene is a testament to his authorship. There are two other scenes that exemplify Hitchcock's technical proficiency and ability to connect his vision with the film's subject matter. A decisive part of the film is when Alex realizes that she has married an enemy of the Nazi party. He drags himself up the stairs, a central feature of a Hitchcock film, to break the news to his mother. Alex, sitting on a chair, says the phrase “I'm married to an American agent”. The image of Alex is a close-up from above with low lighting. This scene denotes a change in Alex's character. He no longer trusts Alicia because she now poses a threat to her facade to the Nazis. In the third scene, the camera takes on Alicia's point of view after she discovers that her husband and stepmother have poisoned her. Alicia jumps out of the chair and... middle of paper... gross, just like you've always been jealous of every woman I've shown interest in," Alex complains to his mother. It's Alex's mother who conceives the he idea of ​​making a potion for Alicia and it is her mother with whom she argues over the keys to the cupboards. The parallel between Alicia's dependence on Devlin and that of Alex on her mother is evident in the final scene of honor of Alex's villa. Influenced by German Expressionism, the stairs play a fundamental role in this and subsequent films. Alicia, supported by Devlin, and Alex, followed by their domineering mother, all descend the grand staircase of the villa under the eyes of the Nazi party. Outside the house, Alicia and Devlin flee to freedom while Alex reluctantly returns up the stairs to his fate with the Nazis. The film's conclusion on the stairs is a testament to Hitchcock's style.
