Five on Finniston Farm (Famous Five 18)

There's a ruined castle on Finniston Farm, but only the dungeons remain - and nobody knows where they are! The Famous Five are determined to find them - and whatever is hidden in them - but they are not alone. Someone else wants to know, too. The question is: can the Five get there first? These classic editions feature Enid Blyton's unchanged text and Eileen A. Soper's original illustrations.
