Penric’s Fox (Penric and Desdemona, #5)

Some eight months after the events of Penric and the Shaman, Learned Penric, sorcerer and scholar, travels to Easthome, the capital of the Weald. There he again meets his friends Shaman Inglis and Locator Oswyl. When the body of a sorceress is found in the woods, Oswyl draws him into another investigation; they must all work together to uncover a mystery mixing magic, murder and the strange realities of Temple demons.
