Blyton and Rowling.
A compare and contrast piece at the Telegraph:
[Intermediaries allow] Rowling to preserve some private life. Blyton had one, too, but in front of it was a manufactured façade. Where Rowling blogs on her website, Blyton wrote chatty letters about her life to her fans through magazines. They concealed as much as they revealed. When she divorced and remarried, the "Daddy" in her letters seemed unchanged. When her terrier, Bobs, died, she continued to write stories in his voice, and told her gardener not to mark his grave, in case a visiting child should stumble upon the truth.
If you're interested in either author, a must read -- I wish it had been longer. Can anyone recommend a good Blyton biography?
