Her name was Connie

I was very disappointed with the ending of this story. I felt like Connie gave in too easily and that she should have stood her ground longer. The sense that I get from Arnold Friend is that he is almost not human. He can see things that are going on from and distance, he knew things about Connie and her family that he should not have known, even the way he spoke and moved around made him seem to be of another dimension. This story almost seemed like I was reading somebody's dream or in this case nightmare. I would like to know what happens after Connie goes with Arnold and if she survived. Did her parents look for her? Did the town get involved?
