I recently watched the silent film with a piano score performed skillfully, which significantly enhanced what is certainly an overextended story. "Alice" (Anny Ondra) has a trivial argument with her police officer boyfriend "Frank" (John Longden), and then somewhat unwisely begins a relationship with a repugnant artist (Cyril Ritchard) who tries to take advantage of the situation, and whom she unintentionally kills in a violent way. Fearing that no one would credit her story, and instead of notifying the police, she runs away – though not before someone sees her, which leads to complications involving a blackmailer with questionable motives (Donald Calthrop, who is well-suited for the part). Simultaneously, the police misinterpret events during their inquiry, resulting in another unfortunate incident—leaving "Alice" burdened by even greater feelings of remorse! It requires some adjustment to accept the rather fixed style of the camera work, but once you understand that you're sharing the same viewpoint as the person operating the camera, it begins to function quite well, allowing for a deeper engagement with a compelling narrative about infidelity and dishonesty. The written explanations are infrequent but effectively supplement Hitchcock’s natural talent for storytelling using the restricted technology available in 1929, which makes clever use of illumination, darkness, and the surroundings of the characters. I don't believe that the sound film released shortly afterward could possibly be as impactful.
