The Canterville Ghost

When a teenage girl moves to England with her brothers and parents into the ancient Canterville Hall, she's not happy. Especially as there's a ghost and a mysterious re-appearing bloodstain on the hearth. She campaigns to go back home, and her dad, believing the ghost's pranks are hers, is ready to send her back. But then she actually meets the elusive 17th-century Sir Simon de Canterville (and the cute teenage Duke next door), and she sets her hand to the task of freeing Sir Simon from his curse.
