A new baby brings an abundance of joy to Isabel Dalhousie and her husband, Jamie--but Isabel's almost four-year-old son, Charlie, is none too keen on his newborn brother. In fact, Charlie refuses to acknowledge Magnus, and Isabel must find a way to impress upon her older son the patience and understanding that have served as guiding principles in her own life. These are, of course, the qualities that bring Rosemary Hipple, an old acquaintance of Isabel's, to seek her help in a tricky situation. Rosemary is something of a matchmaker and has brought together a cosmetic surgeon and a successful banker at her most recent dinner party. But new information comes to light about the cosmetic surgeon that causes Rosemary to doubt the auspiciousness of the match. Isabel agrees to find out more, but her inquiries take an unexpected turn, and she starts to wonder which of the two she should be investigating after all. As ever, her intelligence, quick wit and deep empathy for others will come to her aid as she grapples with the issues that are her bread and butter: friendship and its duties, the obligation of truthfulness and the importance of perspective.
