Having unexpectedly inherited an Elizabethan manor house in rural Norfolk, the new owner Quentin Rivers has asked Phineas Fox to investigate the house’s history. Phin soon becomes immersed in The Tabor’s dark and mysterious past, and in the course of his research uncovers tales of a curious dance, the Cwellan Daunsen: a dance that has not been performed for centuries but whose strange legend still lingers. The dance has a dark side; whenever it took place, children were told to stay indoors – and on no account to look through their windows…
