How did JKR relieve Issacs from his suffering...

"Before it came out, I wasn't quite sure – there was a point where I wasn't sure I was going to do [it] anymore because there wasn't much for me to do in number five and I wasn't in number six. I met Jo Rowling for the first time at a big awards dinner. I went over and basically fell to my knees and said 'Get me out of prison, I beg you.' She looked over her shoulder and looked back at me mouthing, 'You're out. Chapter One.' And that was it, that's all I had to know, and I signed up immediately."
