She turns to her husband Martin for support, only to find that he's too preoccupied to listen to her concerns. When Becca meets Paul Fitzwilliam, he provides a shoulder for her to cry on. And even though she's met his scarily attractive wife, Becca's vulnerable to seduction. Is this the perfect romance - or is Becca about to make the biggest mistake of her life?
