The Turn of the Screw

I had begun The Turn of the Screw, and so far I don't know what to expect from it. The story is a frame story that starts with some friends telling tales around a fire a Christmas Eve when a certain person, Douglas, mentions that he has an interesting tale from the written words of a friend of his. Unfortunately, he was not able to begin telling the story until the following day, which all the friends looked forward to with anticipation. Then begins the story inside the frame, the story of a woman who begins with finding a job as a caretaker and school teacher for two kids. So far, the young woman has met the little girl of the family. One thing that does cause concern in me, though, is that she and the servants of their house puts a lot of emphasis in their "innocence," which makes me question just how sweet, kind, and innocent the children are.
