Writing is like bricklaying; you put down one word after another. Sometimes the wall goes up straight and true and sometimes it doesn't and you have to push it down and start again, but you don't stop; it's your trade.

I think probably the scaredest I've ever been was in Somalia. I arrived there when the episode that became known as 'Black Hawk Down' was still taking place. The Americans were still pinned down under fire. And everybody else was basically going the other way, and I was the only one putting my hand up for a flight in.

It is human nature to imagine, to put yourself in another's shoes. The past may be another country. But the only passport required is empathy.

Write what you know. Every guide for the aspiring author advises this. Because I live in a long-settled rural place, I know certain things. I know the feel of a newborn lamb's damp, tight-curled fleece and the sharp sound a well-bucket chain makes as it scrapes on stone. But more than these material things, I know the feelings that flourish in small communities. And I know other kinds of emotional truths that I believe apply across the centuries.

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.

It is natural to want to forget, Anna, when everyday is a brimful of sadness. But those souls also forgot those that they had loved. You do not want that, surely? I have heard some preach that God wants us to forget the dead, but I cannot believe so. I think He gives us precious recollections so that we may not be parted entirely from those He has given us to love. You must cherish your memories of your babes, Anna, until you see them again in Heaven.

Even the classics that we read to our young children are full of wolves' fangs and burning ovens and bloody feet and ice shards piercing hearts. Even the New Testament climaxes with an act of unspeakable torture. Might as well just read to our kids from the Amnesty Annual Report and be done with it.
