Los Angeles: Author J K Rowling has announced that she will release a tale about Dolores Umbridge, who served as the Defence Against the Dark Arts teacher known for her abusive punishments against students in "Harry Potter and the Order of the Phoenix".
The new story is scheduled to be published online on the author's official blog on Halloween Day, October 31. It will unveil the villain's back story and offer "revealing first-person" thoughts about the former Hogwarts professor, reported Ace Showbiz.
The cruel teacher was played by Imelda Staunton. In the on-screen adaptations of the books, she made her debut in the fifth "Order of the Phoenix" and reprised her role in the seventh installment "Harry Potter and the Deathly Hallows: Part I".
Earlier this year, Rowling delighted "Harry Potter" diehard fans by releasing two other stories from the wizarding universe. One revolves around a 33-year-old Harry Potter at the Quidditch World Cup and another gives more depth to singing sorceress Celestina Warbeck.
