I read continually and don't understand writers who say they don't read while working on a book. For a start, a book takes me about two years to write, so there's no way I am depriving myself of reading during that time. Another thing is that reading other writers is continually inspiring - reading great writers reminds you how hard you have to work.

I'm not quite Honoré de Balzac, but I can't start without a strong espresso. After an hour and a half or so, I need another. Nothing else, mind, and certainly not alcohol. Can't imagine anything more ridiculous than drink-writing.

Sometimes, I like to imagine the perfect reader - the reader who not just understands what I am about, but soaks up every word as if it were written for them. I have been fortunate in that I have got to meet such readers now and again.

I find that jazz loosens up the deep place of my mind, lets me find my own strange rhythms. Generally, I find the knottier the jazz, the better. Anything with singing is a distraction. Listening to classical music tends to have the unconscious effect of making my writing too smooth.

I write in Times New Roman, 12 point, and arrange the margins so that the screen looks like a page from a book. This spurs me on to make the writing as perfect as I can make it.

"Night sky was black and then there was blood, morning crack of light on the edge of the earth." The ideal first sentence contains within it an intimation of the whole book 'Red Sky in Morning'. That's what I was hoping for.

I particularly like the catchphrase of Leonardo Da Vinci: Ostinato Rigore! (Which means, pretty much, Relentless Rigor).
