Kazuo Ishiguro is interviewed at the Los Angeles Review of Books; among other things, the writer touches on world-building, jumping genres, and why, sometimes, it takes a little while to get where you’re going:
Well, it took me four years or five years before I came up with my second novel, and that wasn’t a strategy, that was just how long it took. And it didn’t do me any harm at all; I’ve never thought about it since. I don’t feel any pressure in terms of timing. I do feel pressure in terms of what I eventually put out there.
