There was a place in Poole called the Eileen Soper attraction, now sadly closed. She was an illustrator, most recognised for her Enid Blyton books. The place was set up as a Famous Five style mystery so you had to move a 'book' on a library shelf to open a secret door, find a clue in a tunnel/cave, and decode a secret message. There were also displays of her work. It was hugely fun, brilliantly designed, and very informative. My daughter would have loved it.
