"The Fall of the House of Usher" is a short story by Edgar Allan Poe, first published in September 1839 in Burton's Gentleman's Magazine. It was slightly revised in 1840 for the collection Tales of the Grotesque and Arabesque. It contains within it the poem "The Haunted Palace", which had earlier been published separately in the April 1839 issue of the Baltimore Museum magazine.
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. Although Poe wrote this short story before the invention of modern psychological science, Roderick's symptoms can be described according to its terminology. They include hyperesthesia (hypersensitivity to light, sounds, smells, and tastes), hypochondria (an excessive preoccupation or worry about having a serious illness), and acute anxiety. It is revealed that Roderick's twin sister, Madeline, is also ill and falls into cataleptic, death-like trances. The narrator is impressed with Roderick's paintings, and attempts to cheer him by reading with him and listening to his improvised musical compositions on the guitar. Roderick sings "The Haunted Palace", then tells the narrator that he believes the house he lives in to be sentient, and that this sentience arises from the arrangement of the masonry and vegetation surrounding it.
Roderick later informs the narrator that his sister has died and insists that she be entombed for two weeks in a vault (family tomb) in the house before being permanently buried. The narrator helps Roderick put the body in the tomb, and he notes that Madeline has rosy cheeks, as some do after death. They inter her, but over the next week both Roderick and the narrator find themselves becoming increasingly agitated for no apparent reason. A storm begins. Roderick comes to the narrator's bedroom, which is situated directly above the vault, and throws open his window to the storm. He notices that the tarn surrounding the house seems to glow in the dark, as it glowed in Roderick Usher's paintings, although there is no lightning.
The narrator attempts to calm Roderick by reading aloud The Mad Trist, a novel involving a knight named Ethelred who breaks into a hermit's dwelling in an attempt to escape an approaching storm, only to find a palace of gold guarded by a dragon. He also finds hanging on the wall a shield of shining brass of which is written a legend: that the one who slays the dragon wins the shield. With a stroke of his mace, Ethelred kills the dragon, who dies with a piercing shriek, and proceeds to take the shield, which falls to the floor with an unnerving clatter.
As the narrator reads of the knight's forcible entry into the dwelling, cracking and ripping sounds are heard somewhere in the house. When the dragon is described as shrieking as it dies, a shriek is heard, again within the house. As he relates the shield falling from off the wall, a reverberation, metallic and hollow, can be heard. Roderick becomes increasingly hysterical, and eventually exclaims that these sounds are being made by his sister, who was in fact alive when she was entombed and that Roderick knew that she was alive. The bedroom door is then blown open to reveal Madeline standing there. She falls on her brother, and both land on the floor as corpses. The narrator then flees the house, and, as he does so, notices a flash of light causing him to look back upon the House of Usher, in time to watch it break in two, the fragments sinking into the tarn.
