Rosamund and Sam look forward to living at Cleaves, the medieval manor house bought by their new stepfather, Richard. But problems soon arise when Richard takes a dislike to Sam but is embarrassingly over familiar with Rosamund. The room she is given is reputed to be haunted by another Rosamund, who lived there in Tudor times. As her stepfather’s behaviour becomes more threatening, Rosamund’s life starts to mirror that of her Tudor namesake.
