Thank goodness he changed it: Matilda is one of my all-time faves.
From the New Yorker:
But in early drafts of “Matilda,” Dahl had painted her as a wicked child who uses telekinesis to fix a horse race, a pursuit that ultimately kills her. Although Dahl was known for archness, even cruelty—remember Violet Beauregarde, in Willy Wonka’s factory, blowing up into a huge blueberry—the new book seemed unusually savage.
The article is actually more about the stage production of Matilda, but WOW. I clearly really need to read Storyteller.
