Answer question according to the text below.

Henry James is one of America's greatest novelists, and the author of The Turn of the Screw, a well-known short ghost story, published in 1898. It is a story that many people have made into films and operas. One of the best operas is one written by Benjamin Britten in the mid twentieth century.

The book is about a governess who looks after two children in a house which has no near neighbours. The story is both haunting and frightening. The children, Flora and Miles, are charming to their teacher, but when she starts to see the figures of a man and woman in the gardens, she begins to believe that supernatural forces possess them, and will lead to their destruction. The reader and the listener sometimes wonder if the governess is mad, because both author and composer cleverly leave a lot of room for the reader’s / listeners’ own terrible thoughts and ideas.

Ghost stories and music have a similar effect on us. The best ghost stories try to get into our minds, and music has the power to go past our conscious thought and appeal directly to our feelings and emotions. So the terrifying production that opened last night at Covent Garden Opera House is successful for two reasons: first because it has a great author and composer, and second because your imagination takes over from your sensible mind.
