I had to look up Enid Blyton. English writer of children's books. None of which I've read or heard of.
From Wikipedia:
Blyton's work became increasingly controversial among literary critics, teachers, and parents beginning in the 1950s, due to the alleged unchallenging nature of her writing and her themes, particularly in the Noddy series. Some libraries and schools banned her works, and from the 1930s until the 1950s the BBC refused to broadcast her stories because of their perceived lack of literary merit. Her books have been criticized as elitist, sexist, racist, xenophobic, and at odds with the more progressive environment that was emerging in post-World War II Britain, but they have continued to be bestsellers since her death in 1968.
