My work is less violent because we tend to write what we want to read... and I'm not that interested in gruesome books. Any violence, to fit in well with a crime novel, has to have compassion.
A writer loses possession of her work as soon as it's reaches its audience. Each reader brings his own experience and prejudice and imagination to the work. Television adaptation just goes one step further, and the novelist has to learn to let go.
I write traditional drama, and the small enclosed communities work well with this form. I enjoy exploring secrets. On small islands, privacy is important, and there are secrets that everyone can guess but nobody talks about.
