I figured that to be a writer I would need to have been born in the nineteenth century, be British, or have three names. So I turned my sights elsewhere . . . to acting.

When I left the theatre and turned to writing, one of the big pulls was that, unlike the theatre, I didn't have to wait to be hired before I could do my art. That was huge. But you still have to figure out how to support your habit; it's rare and lucky when art pays the bills.

That requires quite an imaginative leap because it's hard for me to imagine that my biography would be of much interest to anyone, and because I'm a fairly private person, the notion doesn't appeal to me.

One of the nice things about moving from acting to writing is that your work can be in the public eye without having to be in the public eye yourself. I guess that's not completely true. If you're lucky - and I have been - there are book tours and lectures. I don't have stage fright, and I enjoy meeting people, so that's easy and enjoyable, but it's not a constant, and it's not celebrity.

If you had told me twenty years ago that I would write a novel set in Russia, much less two, I simply wouldn't have believed you. I had no familiarity with Russia or its history, but part of what drives me as a reader, and more and more as a writer, is curiosity, the desire to explore unfamiliar terrain and inhabit alternate lives.

I tell my students, if you're interested in marine biology or llama farming, follow that string. Yes, it will probably take you a longer time to write that book, but it's not a race. That's another great thing about being a writer: you don't age out.

Once I had started, I discovered the secret pleasure of writing a novel. It's such an immersive, deep commitment. With short stories, you're continually having to start again from scratch, but with a novel you only need one good idea every few years.
