I don’t know how to write. Which is unfortunate, as I do it for a living. Mind you, I don’t know how to live either. Writers are asked, particularly when we’ve got a book coming out, to write about writing. To give interviews and explain how we did this thing that we appear to have done. We even teach, as I have recently, students who want to know how to approach the peculiar occupation of fiction writing. I tell them at the beginning—I’ve got nothing for you. I don’t know. Don’t look at me.

I’ve written six books now, but instead of making it easier, it has complicated matters to the point of absurdity. I have no idea what I’m doing. All the decisions I appear to have made—about plots and characters and where to start and when to stop—are not decisions at all. They are compromises. A book is whittled down from hope, and when I start to cut my fingers I push it away from me to see what others make of it. And I wait in terror for the judgements of those others—judgements that seem, whether positive or negative, unjust, because they are about something that I didn’t really do. They are about something that happened to me. It’s a little like crawling from a car crash to be greeted by a panel of strangers holding up score cards.

Something, obviously, is going on. I manage, every few years, to generate a book. And of course, there are things that I know. I know how to wait until the last minute before putting anything on paper. I mean the last minute before the thought leaves me forever. I know how to leave out anything that looks to me—after a while—forced, deliberate, or fake. I know that I need to put myself in the story. I don’t mean literally. I mean emotionally. I need to care about what I’m writing—whether about the characters, or about what they’re getting up to, or about the way they feel or experience their world. I know that my job is to create a perspective. And to impose it on the reader. And I know that in order to do that with any success at all I must in some mysterious way risk everything. If I don’t break my own heart in the writing of a book then I know I’ve done it wrong. I’m not entirely sure what that means. But I know what it feels like.

I do no research. Given that I’ve just written a book that revolves around two London Met police detectives, this might seem a little foolhardy. I have no real idea what detectives do with their days. So I made some guesses. I suppose that they must investigate things. I tried to imagine what that might be like. I’ve seen the same films and TV shows that you have. I’ve read the same sorts of cheap thrillers. And I know that everything is fiction. Absolutely everything. Research is its own slow fiction, a process of reassurance for the author. I don’t want reassurance. I like writing out of confusion, panic, a sense of everything being perilously close to collapse. So I try to embrace the fiction of all things.

And I mean that—everything is fiction. When you tell yourself the story of your life, the story of your day, you edit and rewrite and weave a narrative out of a collection of random experiences and events. Your conversations are fiction. Your friends and loved ones—they are characters you have created. And your arguments with them are like meetings with an editor—please, they beseech you, you beseech them, rewrite me. You have a perception of the way things are, and you impose it on your memory, and in this way you think, in the same way that I think, that you are living something that is describable. When of course, what we actually live, what we actually experience—with our senses and our nerves—is a vast, absurd, beautiful, ridiculous chaos.

So I love hearing from people who have no time for fiction. Who read only biographies and popular science. I love hearing about the death of the novel. I love getting lectures about the triviality of fiction, the triviality of making things up. As if that wasn’t what all of us do, all day long, all life long. Fiction gives us everything. It gives us our memories, our understanding, our insight, our lives. We use it to invent ourselves and others. We use it to feel change and sadness and hope and love and to tell each other about ourselves. And we all, it turns out, know how to do it.
