The Fall of the House of Usher, a 19th century Gothic short story indirectly deals with the theme of incest between the protagonist Roderick Usher and his twin sister Madeline. The author takes the utmost care not to mention the term anywhere in the text but rather conveys it through the description of the extraordinary nature of their family. Gothic thrives on transgression: incest, rape, perversion, crime, insanity, and death are prominent themes within the Gothic tradition, which embodies an obsession with the darker side of human life. The recurrent violation of taboos represented in Gothic fiction is closely tied to its primary strategy of evoking terror and fear in the recipient.
