Rowling sheds some light on wicked character Dolores Umbridge

Hold on to your wands, JK Rowling has returned to the wizarding world of Harry Potter to delve into one of the book’s most despicable characters.

As a special Halloween treat, Rowling’s site www.Pottermore.com published a 1,700-word explainer about Dolores Umbridge, the witch who torments Harry Potter and makes him cut the words “I must not tell lies” repeatedly into his skin.

The author reveals Umbridge is based on a former teacher of hers, describing her as a person she “disliked intensely on sight”.
