The narrator arrives at the House of Usher riding on a horse. Roderick Usher invites the narrator through a letter to help him overcome his agitation of his soul. The narrator sees the building sickly and Roderick Usher as pale and weak. The house and Usher resembles the state of Usher himself. '' I had been passing alone, on horseback, through a singularly dreary tract of country; and at length found myself, as the shades of the evening drew on, within view of the melancholy House of Usher".
Usher reveals that his twin sister Madeline is dying. Lady Madeline eventually passes out. Usher decides to keep her in a vault until a proper burial. The narrator notices that Madeline's cheeks and chest is still flushed. Usher's mentality worsens after her death. " On the closing in of the evening of my arrival at the house, she succumbed ( as her brother told me at night with inexpressible agitation) to the prostrating power of the destroyer".
Shortly after Lady Mandaline's death, the narrator starts to hear strange noises in the house. One night, during a storm, Usher comes to the narrator's room and notices the storm outside. The narrator then reads a book to calm down Usher. " The antique volume which I had taken up was the Mad Trist of Sir Launcelot Canning but I had called it a favorite of Usher's".
As the narrator reads the book the sounds described are heard in the house. As he keeps on reading they hear a loud scream. Usher starts to rock back and forth. He starts mumbling that he has heard sounds coming from his sister's coffin and is afraid that he buried her alive. Then the door flies open, and reveals Lady Madeline covered in blood. " It was the work of the rushing gust-but then without those doors there did stand the lofty and enshrouded figure of the lady Madeline of Usher. There was blood upon her white robe"
Madeline falls on Usher and dies. Roderick Usher also dies at the same time, most likely due to fear. The narrator runs away from the house. " In her violent and now final death agonies, bore him to the floor a corpse, and a victim to the terrors he had anticipated."
As the narrator is running away he turns back to watch the house start to fall apart. Eventually, the house collapses and there is no more House of Usher. " From that chamber, and from that mansion, I fled aghast."
