The fall of the house of usher

The narrator goes to the house of Usher to visit an old friend. It is a big house and only the friend and his sister live there. They are the last of the Ushers and are both quite sick. The house seems to be dying with the family. Roderick gets nervous about everything and his senses are all extreme. He can't listen to anything but string interments, or eat anything but bland foods. His sister has spells where she looks like she is dead. She will go into a coma like stage and nobody really knows if she is alive or dead. While the friend is visiting Roderick buries his sister alive on purpose. He wants the family to be gone and everything to be destroyed.
