To be a writer was always my greatest aim. I remember writing a play about Guy Fawkes when I was 10. I suppose it's significant, at least to me, that my first work should be about a historical figure.
Why should a novelist not also be a historian? To force unnatural divisions within the English language is to work against its capacious and accommodating nature. To expect a writer to produce only novels, or only histories, is equivalent to demanding from a composer that he or she write only string quartets or piano sonatas.
There are so many characters whizzing around inside my head, it's like Looney Tunes. But as soon as I've finished writing about them, I completely forget who they are.
Oh, I just tend to believe in things when I'm writing them. For instance, when I was writing 'Doctor Dee,' I believed in magic. And when I wrote 'Hawksmoor' I believed in psychic geography. But as soon as I type the last full stop, I'm back to being a complete blank again.
