Enid who?? Blyton. An incredibly prolific writer of children's books in England. Just "voted" the Most Cherished Author. (þ: Literary Saloon)
ETA: I actually know (and love) Ms. Blyton. Over the years I've collected her school stories, her Famous Five and Five Find-Outers mysteries and her Nature Books. For some odd reason, she's virtually unknown in the US, and her books are not published here.
