The One and Only by Carole Mortimer
A night spent in the arms of Marcus Ballantyne! It happened to Joy-but not without the leading TV actor thinking she was a married woman with a string of lovers! In reality Joy was a provincial librarian who hadn't had a night out since her boyfriend jilted her-how on earth had she landed herself in this mess? And how could she convince Marcus that she wasn't just another good-time girl hoping to be a notch on his bedpost, but that he was the one and only man she'd ever love?
