The Turn of the Screw by Henry James

An unnamed narrator listens to a male friend reading a manuscript written by a former governess whom the friend claims to have known and who is now dead. The manuscript tells the story of how the young governess is hired by a man who has become responsible for his young nephew and niece after the death of their parents. He lives mainly in London and is not interested in raising the children himself.

The boy, Miles, is attending a boarding school, while his younger sister, Flora, is living at a country estate in Essex. She is currently being cared for by the housekeeper, Mrs. Grose. The governess's new employer, the uncle of Miles and Flora, gives her full charge of the children and explicitly states that she is not to bother him with communications of any sort. The governess travels to her new employer's country house and begins her duties.
