I've never put Northern Ireland into a novel because it's not my territory. I come from the South, so my imaginative territory is very much the Republic of Ireland rather than the North. Even though, if I wrote a novel about the North, it might sell more.

If you have to read to cheer yourself up, read biographies of writers who went insane.

I am violently untidy. My desk is overcrowded. I write my first drafts in longhand in a long notebook using a plastic throwaway fountain pen. Then I work on a word processor using a different desk and a different room.

I write with a sort of grim determination to deal with things that are hidden and difficult and this means, I think, that pleasure is out of the question. I would associate this with narcissism anyway and I would disapprove of it.

You create a world away from home and make new rooms for yourself. But when you arrive back home in your old rooms, the world you've made for yourself ceases to be real. Everything seems to crumble. Anyone who's been sent away to boarding school can understand that.

When a book comes from the publisher and you see it for the first time... Of course it's not remotely like seeing a baby for the first time, but I can remember with each book what room I was in when I opened it. That would be excitement, though, I think. Not pride.

I live in words. I like looking at things, but I don't have a strong visual imagination.
