My solo travels in Paris have brought many perfect hours of being alone but not a moment of loneliness. People who depend on other people are often in hiding from themselves. Two and a quarter million people live in the City of Light: you will see many of them and you will pass them in the street, but when you see Notre Dame after dark and walk home and perhaps stop to have a drink in the Marais, you can feel that the only thing that is missing from your experience is the common dependence on someone to distract your attention. You are living without it: you are on vacation.

Writing a novel is an act of self-annihilation as much as self-discovery. You can kill whole appetites and flood whole depths while plumbing them, but if you are serious about it you also get to put something into the world that wasn't quite there before.

I was 10 when I realised I couldn't stand football. I'd tried, obviously, before this - no one wants to give in to social pariah-hood without a fight. I had stood frozen on pitches, done some running about and shouted a lot, as though I cared.

Always trust strangers, it's the people you know that let you down.

Like children all over the world, by the age of 10 I'd come to believe that most of the really humane creatures were not really human at all.

I'm not interested in writers who are overcome with certainty, with single-mindedness, or with a sense of how consistent and morally upstanding they are. My writers are in the thick of it and they seek the truth, rather than embody it, and sometimes they find truths that don't sit palatably or easily together. That's life. That's personality. And that's writing.

It was beguiling to live in a country, Scotland, that didn't look enough like itself to be a location for its own movies... I remember consulting a film book and discovering that Arthur Freed decided to shoot Brigadoon in Hollywood because nowhere in Scotland looked Scottish enough.
