I was a news reporter for 16 years, seven of them a foreign correspondent in the Middle East, Africa and the Balkans. Perhaps the most useful equipment I acquired in that time is a lack of preciousness about the act of writing. A reporter must write. There must be a story. The 'mot juste' unarriving? Tell that to your desk.

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.

Certainly I'm still mining my experiences as a journalist. I think it's no coincidence that all three of my novels basically are about how people act in a time of catastrophe. Do they go to their best self or their worst self?

And at this moment in history, our core value happens to be the raw, aching truth of the human predicament. It may also be the only belief that can save us as a species. A species that will continue to find comfort and delight in the companionship of animals, the miracle of birds, the colours of the corals and the majesty of the forests. We are in it together, on this blue spinning marble in the cold and silent void. And we must act on that belief, if we are going to be able to continue to live a good life here, in this beautiful and fragile country, on this lovely planet, our only home.

How strange it is, Anna. Yesterday, I have filed in my mind as a good day, notwithstanding it was filled with mortal illness and the grieving of the recently bereft. Yet it is a good day, for the simple fact that no one died upon it. We are brought to a sorry state, that we measure what is good by such a shortened yardstick.

You go on. You set one foot in front of the other, and if a thin voice cries out, somewhere behind you, you pretend not to hear, and keep going.

If a man is to lose his fortune, it is a good thing if he were poor before he acquired it, for poverty requires aptitude.
