For months, I’d started to think I’d made a mistake in trying to write the best book I could. I should have written a bad Jackie Collins rip off. “It was wrong, but there was something about the way he cocked his head that couldn’t quite be… and then he looked at her and smiled… as people do when they see someone… but really see them… with an apologetic insight, with a smile they can’t stop…” blah, blah, blah. And then, today, for the first time, I smashed 50 Shades in sales. At last! I was beginning to worry that either the world had gone mad, I’d gone mad, or I was in love with a page boy called… Bob. Next stop: Waterstones Warrington, 25 August.
