Beverley, Elsie, and Margot are not your average housewives. They are all wives of convicted killers. During the sun-drenched summer of 1966, the three women form an unlikely friendship after the discoveries of their husbands' brutal crimes. With their exes dead or behind bars, the women attempt to forge new futures for themselves. Headstrong Beverley compulsively tries to maintain control of everything around her, all while raising two children. Bookish Elsie fights day in and day out for the chance to make a name for herself in the newsroom, working among men who sneer at her career goals. Glamorous Margot refuses to take anything seriously and devotes all her energy to upholding the appearance that everything is fine--anything to quell the shame from her husband's deceit. They know people look at them and think only one thing: How could they not have known their husbands were committing horrific crimes? How much guilt is theirs to carry? And yet, when a string of killings hits the news, the three women--underestimated, overlooked, shrewd--decide to get to work. After all, who better to catch a killer than those who have shared their lives and homes with one?
