A humorous fantasy from Diana Wynne Jones. In a world next door to ours, the tourist industry is devastating the population by its desire to experience all the fantasy clichés - Dark Lords, impoverished villages, dragons etc.

The Head of the University resolves to shut the tours down; the only problem being the ruthless tour-master - and his all-powerful demons. To save them all, the incompetent wizard Derk is appointed as Dark Lord in the hope that he will ruin the tours, and sure enough proceeds to fail at everything due to his general uselessness. But can failing at everything lead to a win this time?
