Sunday morning, New Year's Day, Inverness airport and a seasonal burst of highland snow grounds all flights. Lucy finds herself agreeing to share her hire car and the drive back to London with a total stranger, the man standing behind her in the queue. Their drive becomes a journey through a winter wonderland, a cocooned world inside a world. For just a few hours Lucy is separated from reality and finds herself thinking and behaving in a way she never would in normal life. And then several weeks later, when life has begun to re-establish itself so that Lucy can no longer even remember his face, and blushes whenever she tries, an ad appears: a small red car on a dark green poster emblazoned with the words LUCY BLUE, WHERE ARE YOU? I SAW YOU in Inverness airport. You were the girl in the blue coat arguing with the man from Rentacar at 8.30 am on Sunday 12 February. I was standing behind you... He wasn't meant to do this. They were not meant to ever see each other again. And reading the ad, Lucy could only wish passionately that she had never laid eyes on him, let alone the hands and lips (and everything else too) in a Welcome Break motel, junction 17, just north of Edinburgh.
