Summary Spring warms the air in an upscale cul-de-sac in western Connecticut, and with the shedding of jackets comes the startling discovery that one of four homeowners — a beautiful young widow named Gretchen — is pregnant. Since she rarely leaves home, the three most likely suspects are the husbands of her three neighbors, each of whom has spent time with her in the year since her husband passed on. Preposterous? Not at all. One of those husbands has a history of infidelity. The second is married to a woman who, as CEO of her own business, is often out of town. The third has a special problem: he and his wife are struggling with infertility treatments. For Graham and Amanda, sex has become programmed and cold. Amanda wonders just how much her husband misses the spontaneous passion they once had and whether he might have found it elsewhere. With Gretchen as a catalyst, the three couples take stock of their marriages. As the mystery deepens, blame and mistrust threaten what each of them holds most dear.
