Henry James 
Turn of the Screw [PDF ebook] 

The Turn of the Screw is s ghostly Gothic tale by Henry James. A masterpiece in ambivalence and the uncanny, The Turn of the Screw tells the story of a young woman who is hired as governess to two seemingly innocent children in an isolated country house. As the tale progresses she begins to see the ghost of her dead predecessor. Or does she? The story is so ambivalent and eerie, such a psychological thriller, that few can agree on exactly what takes place. James masters "the strange and sinister embroidered on the very type of the normal and easy" in this chilling Victorian classic.
