If one tries to think about history, it seems to me - it's like looking at a range of mountains. And the first time you see them, they look one way. But then time changes, the pattern of light shifts. Maybe you've moved slightly, your perspective has changed. The mountains are the same, but they look very different.

Having the urge to write a novel, especially if you've yet to be published, is like having a medical condition impossible to mention in polite company - it's a relief simply to know there are fellow-sufferers out there.
