You can't write about the past and ignore religion. It was such a fundamental, mind-shaping, driving force for pre-modern societies. I'm very interested in what religion does to us - its capacity to create love and empathy or hatred and violence.

I was really interested in how marriages work, how you can, you know, be in love with somebody and spend many years with your lives intertwined, but in the end another soul can be fundamentally unknowable. And I think that the stress of war, when one party goes away and the other has to deal at home, is a really testing time in a lot of marriages.

We were too intelligent, too cynical for war. Of course, you don't have to be stupid and primitive to die a stupid, primitive death.

I am not part of that earlier Australian generation who set off on a deliberate search for fame and fortune in distant lands. My generation was the first that didn't need to. By the 1980's when I left home, our culture had grown deep enough and wide enough to encompass all but the most rarefied of ambitions.

The brave man, the real hero, quakes with terror, sweats, feels his very bowels betray him, and in spite of this moves forward to do the act he dreads.

The thing that most attracts me to historical fiction is taking the factual record as far as it is known, using that as scaffolding, and then letting imagination build the structure that fills in those things we can never find out for sure.

Despair is a cavern beneath our feet and we teeter on its very brink.
