Julian, Dick, Anne, George and Timmy the dog find excitement and adventure wherever they go in Enid Blyton's most popular series. In book eleven, the Famous Five are on an adventurous holiday in horse-drawn caravans. They discover a ruined castle that looks deserted. But is that a face at the window? Or is it a trick of the light? Just who is hiding in the castle? This edition features the text from the Classic edition and contains the original cover art and inside drawings by Eileen Soper.
