The story opens with a narrator—an old friend of Roderick Usher—arriving at the Usher mansion in response to a desperate letter. The mansion is ancient, crumbling, and unnaturally eerie, standing by a black tarn under an oppressive sky. From the moment he enters, the narrator feels a sense of doom and sickness clinging to the place.
Roderick Usher, pale and nervous, confesses that both he and his sister Madeline are afflicted by a strange malady. He believes the house itself is alive and somehow intertwined with their fates. Madeline is weak, ghostly, and wanders the halls like a shadow. Roderick seems to teeter on the edge of madness, plagued by supernatural fears and strange music.
