There were in life rarely, if ever, "right" decisions, never perfect ones, only the best to be made under the circumstances.

I had been a reporter for 15 years when I set out to write my first novel. I knew how to research an article or profile a subject - skills that I assumed would be useless when it came to fiction. It was from my imagination that the characters in my story would emerge.

Work less than you think you should. It took me a while to realise there was a point each day when my creativity ran out and I was just producing words - usually lousy ones - for their own sake. And nap: it helps to refresh the brain, at least mine.

I found 'The Twin' sitting on a coffee table at a writers' colony in 2009. It carried praise from J.M. Coetzee. That seemed ample justification for using it to avoid my own writing. I finished it - weeping - a day later, and I've been puzzling over its powerful hold on me ever since.

So the premise of 'The Submission' is that there's an anonymous competition to design a 9/11 memorial and it's won by an American Muslim, an architect born and raised in Virginia, and his name is Mohammad Khan.

Jealousy clings to love's underside like bats to a bridge.

My parents are aging and there are difficult issues. It's strange to have children at the beginning of life and parents nearing the end.
