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.

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.

Spending a lot of time away from home was strange. My parents visited me, obviously, but I was in hospital a lot, alone. And then when my health had improved a bit and I was in a sick-bed in the house, with the life of the house going on around me, that was very vivid for me. I always think that's a bit like the position of a novelist in a novel, going through drafts: there but not there, one remove from reality.

We are all, Esme decides, just vessels through which identities pass: we are lent features, gestures, habits, then we hand them on. Nothing is our own. We begin in the world as anagrams of our antecedents.

Listen. The trees in this story are stirring, trembling, readjusting themselves. A breeze is coming in gusts off the sea, and it is almost as if the trees know, in their restlessness, in their head-tossing impatience, that something is about to happen.

When my family moved from Ireland in the 70s, Britain was such a difficult place to be Irish. It was a decade of real social and economic upheaval in Britain. There were strikes, the three-day week, the oil crises, huge inflation, the winter of discontent and, what was it, four Prime Ministers? And relations between Britain and Ireland at that time were at an all-time low. I was born in the year of Bloody Sunday and of course the pub bombings happened in the mid-1970s.

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.
