I believe that if writers want their readers to care about a character, they have to care themselves. I have to root for a detective who screws up as much as Thorne does, who shares my birthday, my North London stomping ground, and my love of country music, both alt and cheesy.

My dad was a terrible father. Dreadful. But he had a very difficult childhood. He was fostered - he never knew who his father was. So he had a very different attitude to family and kids. I don't have any issues. I'm not suffering some secret angst.
