Enid Blyton’s Famous Five series has acquired a reputation, since the first book, Five on a Treasure Island, was published in 1942, for being the most wholesome family entertainment imaginable.
Each of the novels revolved around four children – Julian, Anne, Dick and George – and their dog Timmy, all of whom got involved in mild scrapes in an unchanging English countryside, where modern technology (or war) were never mentioned and where the characters were held in a permanent pre-pubescence.
