I was knocked down and dragged by a police Land Rover in a hit-and-run.

I find it easier to write in the winter in Melbourne. When the weather is good you want to go out for a walk, ride a bike, go to a cafe or something. When it's raining, when it's a miserable day, I just sit down at my desk and get some work done.

I love the trilogy form. I like the idea that you can establish a character in book one. And then in the second part, you can take the characters down to their darkest point. And then in the third part, you have total freedom either to give them redemption - or just to kill them.

I had gone to New York with no plan at all. I did a lot of jobs - barman, teacher, security guard, postman and construction worker - and I was meeting many eccentric characters, and they were saying funny things, which I always wrote down.

At home I drive an old Land Rover.

I did the same thing as every Irish person who comes to New York. I arrived on a Wednesday, and by Saturday night, I was pulling pints at a pub in the Bronx.
