But there was one story that disturbed me in the more complicated way I would only later come to realize as a hallmark of the true genius of horror fiction. While the other stories left me with a kind of moonlit Halloween glow, this one put a spade into my settled earth and overturned it. I felt weirdly sick after reading it. I felt injured in some obscure way, as though it had betrayed a trust. The story was “The Monkey’s Paw,” by W.W. Jacobs.
