I am totally blown away by the bbc radio drama Pilgrim series by Sebastian Baczkiewicz. It features a fascinating protagonist William Palmer. The premise is that he was cursed on the way on the way to Cantebury when he encountered the King of the Grayfolk, Faery. He denied the existence of Faery, being a truly pious pilgrim. The king then cursed Palmer to immortality, denying him a normal death. From that time to this William Palmer has walked the world trying to protect humans ("hotbloods") from the wicked caprices of the grayfolk and other supernaturals he encounters between the everyday world and the Otherworld. A fabulous basis for chilling dramas.
