The fairies are experiencing some very puzzling events, which turn the entire village on its head. Finally Thalia finds a clue in an old book - the village must be haunted by invisible tricksters. No one believes her, except Salmacis, the Spirit of the Well, who gives Thalia a clue about how to rid the villages of these little pests. Thalia has to use all her cunning to devise a plan, which involves sparkling objects, a piece of cake and a spectacular sunset. Luckily this proves successful in the end and the fairies can resume their busy lives.
