Lady Margaret Priam is concerned about her good friend Dianne Stark, the woman who seems to have everything. But Dianne is clearly worried about something, and dissatisfied with her perfect life--which makes Margaret examine her own life with questions, too. When Dianne's visiting sister is murdered, the possible criminals include a mugger, someone who doesn't care for the flirtatious Karen, or someone who mistook her for Dianne. Then Margaret confronts the murderer, and the plot seems to tip even further into implausibility. Not my favorite of the Priam books.
