“ Novel-writing can be a cold-blooded business. One uses whatever happens to be lying around in memory and employs it to suit one’s end….Then, again, during the months whilst one is writing about the past, a story is colored by what presently is happening to its writer. So, imperceptibly, the tone of voice changes, original intentions slip away. And I found myself looking through another window at a darker landscape inhabited by neither the present nor the past. ”
