Published in 1898, The Turn of the Screw is Henry James’s best-known ghost story. Ghost stories were very popular at the end of the 19th century, when there was also much interest in the supernatural. 

James begins his novella with a prologue, an introduction to the main story. A group of friends is spending Christmas together in an old country house. One evening they decide to tell each other ghost stories. One of the guests says that he once read a very frightening one. Of course everyone wants to hear it, so he has the pages of the story sent from his house in London. A couple of nights later he reads it to his friends. The story forms the main part of the novella. It is written by a young governess about her first job.

She is employed by a young, handsome man to look after his young nephew and niece—Miles aged 10 and Flora aged 8. They live in a large house in the country called Bly and they are both very beautiful and good. Soon after her arrival the governess sees—or imagines she sees—the evil ghosts of two dead servants, a man called Quint and a woman called Miss Jessel. She is convinced that the ghosts are communicating with the children and that they are going to hurt them. She decides that she must save her pupils before it is too late. 

Are the children really in danger? Or is the governess mad? Henry James leaves it to the reader to decide.
