[William] Eggleston's photographs look like they were taken by a Martian who lost the ticket for his flight home and ended up working at a gun shop in a small town near Memphis. On the weekend he searches for the ticket - it must be somewhere - with a haphazard thoroughness that confounds established methods of investigation.

The process of book writing for me is entirely one of trial and error.

I think, about the distinction between fiction and nonfiction. Fiction is not really about anything: it is what it is. But nonfiction - and you see this particularly with something like the BBC Samuel Johnson Prize for Non-Fiction - nonfiction we define in relation to what it's about. So, Stalingrad by Antony Beevor. It's "about" Stalingrad. Or, here's a book by Claire Tomalin: it's "about" Charles Dickens.

The ideal is to feel at home anywhere, everywhere.

Like most writers I spend a lot of my time sort of thinking, "It's such agony, I can't do it."

Each of my book arrives at a form and a style that is appropriate to the subject.

I think I can recognize when a piece is at a state of completion. I always say to my wife, "Oh yeah, it's roughly finished." I've got it there. And then there's that whole other phase of moving on to properly amp up the sentences and sometimes to move stuff around as well.
