I loved the Famous Five books too - wonderful stuff. And the William books, and Biggles and his female counterpart, Worrals. And all those wonderful Chalet School books.
And does anyone remember the 'Classics' comics where they presented classic novels in comic-book format? They used to have an amazing range: I particularly remember The Three Musketeers, The Man in the Iron Mask, Robin Hood, Ivanhoe, Moby Dick, Treasure Island. Great stuff, I wish they still made comics like that.
