The Famous Five are having a brilliant time - on holiday in horse-drawn caravans - and they've discovered a ruined castle nearby! The castle looked deserted from a distance - but is that a face at the window? Or is it a trick of the light? The Famous Five just have to find out! Just who is hiding in the castle? These classic editions feature Enid Blyton's unchanged text and Eileen A. Soper's original illustrations.
