The Red Cavalier

Twin Turrets, the Yorkshire mansion where Sir Robert Grainger, adventurer and collector, was murdered for a fabulous ruby, is the subject of a fierce competition between Vandelia Egerton and Prince Kassim Bardai, who both want to rent the property. Miss Egerton is triumphant, but her stay is haunted by mysterious vandalism and appearances by Sir Grainger's ancestor, the Red Cavalier.
