I do always know where I'm going in my books. I know the endpoint. I've written only two thousand words of my next novel but I know what the ending will be already.

I wanted to write a book that imagined where advances in the study of genetics might lead us.

Living in France means I see the UK in snapshots. There is something quite nice about being in exile and the things you remember about places tend to be the most vivid details. You don't get that when you see somewhere every day.

Social mobility decreased under Labour and under the current government it is reversing. The differences between the poorest and richest are returning to Victorian levels.
