Die Tapetentür (literally "The Wallpaper Door", but translated as The Jib Door, 1957) is a novel by Austrian author Marlen Haushofer. It depicts the failing relationship between the introverted, sensitive protagonist and her professionally successful, extroverted, unfaithful husband. The novel offers an early example of Haushofer’s exploration of the themes of individual loneliness and alienation, as well as the longing to break free from social conventions.
