New Hyde Hospital’s psychiatric ward has a new resident. It also has a very, very old one. Pepper is the surprised inmate of a mental institution in Queens, New York. In the darkness of his room, on his first night, a terrifying creature with the body of an old man and the head of a bison nearly kills him before being hustled away by the hospital staff. It’s no delusion: The other patients confirm that a devil roams the hallways when the sun goes down. Pepper rallies three other inmates in a plot to kill the monster that’s stalking them. But can the Devil die?
