I try not to be too precious about my writing, and I try to be willing to walk away from it for a few hours when something's not working, to let things percolate a bit. I try not to hide myself away from life too much, because I think that's a risky thing for a writer to do.

When I worked at The Independent newspaper, I had colleagues who would laugh and say that whenever they picked up the phone to my dad and heard his accent, they thought they were about to hear a five-minute warning to get out the building. People in Britain have always thought it acceptable to make racist remarks about the Irish. The prejudice underlying that supposed joke was everywhere.

Motherhood is all-encompassing, and in a way, as the mother, you're the star of the household.

For a while I used to listen to those whispers about babies costing you books, and Cyril Connolly's loathsome quote that "There is no more somber enemy of good art than the pram in the hall." But it's rubbish. Absolute rubbish. A huge amount of your work is done when you're not at your desk. Knotty problems that you need your unconscious to solve. So it can be helpful to walk away and focus on other things and it can be helpful to be a bit harassed in your daily life, to be hungry for time to write.

As other authors have realized, heat can have a strange effect on us, can cause odd chemical reactions in the brain. Heat can bring out secrets; it can change people's personalities.

I think it was Rose Macaulay who said, "A house unkept cannot be so distressing as a life unlived."

My husband, William Sutcliffe, the writer, is my first reader and in many ways my most important. That initial reading of the manuscript is crucial and irreplaceable and you want them to approach it as someone in a bookshop might, not knowing much about it. So I've got into this pattern of not telling Will anything about the book I'm working on. He often knows nothing about the book I'm working on at all until I give him the whole manuscript and ask him to read it. The book I'm working on at the moment he knows nothing about. No one does.
