The Five Jars is the only novel written by James, who is best known for his ghost stories. It is a peculiarly surreal fantasy apparently written for children. While he is out walking, the narrator is drawn to a remote pool, and finds a small box that has been hidden since Roman times. He gradually learns how to use its contents, fighting off a series of attempts to steal it, and becomes aware of a strange world hidden from our own. (Summary by Peter Yearsley)
