It was all coming out from somewhere, and I just had the job of writing it down. I was, however, determined that the central characters would have a happy ending, but it was quite difficult sometimes to get them out of trouble.

It was as though there was a film going on inside my head, and I was watching it as it went by. I was completely immersed in this. I didn't know what was coming, but it just came.

I read a lot of archaeology and early history in a general way, not thinking particularly of this book, and this provided me with the background. It showed me how, possibly, the people lived back then.

Keep it light so you can say a lot more, especially if it's something you care about.
