JK Rowling has hit out at a Twitter critic who attacked her for making Hogwarts headmaster Albus Dumbledore gay.
The author posted a message saying that she had "hated killing off" some of her most loved characters in the final Harry Potter novel.
In response, one angry user responded: "Once u revealed Dumbledore was homosexual I stopped being a fan. Nice how u blindsided us with that one. Enjoy your billion $ (sic)."
Rowling, who has been bombarded by Twitter trolls for her support of the 'Better Together' Scottish referendum campaign, noticed the reply and posted a sarcastic one back.
