"The Fall of the House of Usher" is a short story by Edgar Allan Poe. The tale opens with the unnamed narrator arriving at the house of his boyhood friend, Roderick Usher, having received a letter from him in a distant part of the country complaining of an illness and asking for his help. It is revealed that Roderick's twin sister, Madeline, is also ill and falls into cataleptic, death-like trances. Roderick believes the house he lives in to be sentient, and that this sentience arises from the arrangement of the masonry and vegetation surrounding it.
"The Fall of the House of Usher" was published in September 1839 and is considered the best example of Poe's "totality", where every element and detail is related and relevant.
