Four young women allegedly witness a terrifying apparition while walking in the woods. Has the devil really revealed himself to them? Are they genuine victims of demonic possession? Or, as most suspect, is their purpose in claiming all of this considerably more prosaic?The eyes of the country turn to a small Nottinghamshire town, where an inquiry is to be held. Everyone there is living through hard, uncertain times. The king is recently dead. It is a new century - a new world looking to the future.
