With every book, you go back to school. You become a student. You become an investigative reporter. You spend a little time learning what it's like to live in someone else's shoes.

Your memory is a monster; you forget - it doesn't. It simply files things away. It keeps things for you, or hides things from you - and summons them to your recall with a will of its own. You think you have a memory; but it has you!

I believe that, in any novel of mine, the principal objective is the construction of the whole.

Sigmund Freud was a novelist with a scientific background. He just didn't know he was a novelist. All those damn psychiatrists after him, they didn't know he was a novelist either.
