When Berta Harris of E.J.'s Weight Watchers' group succumbs to an untimely death, the twelve-step groups in attendance at her memorial service have plenty of explanations for why she died. But amateur sleuth E.J. has her own questions: why was Kerry Killian, an old friend and the realtor selling Berta Harris's house, murdered the day after E.J. questioned her? What does this have to do with the mysterious death of Berta Harris? And why would anyone in the group want to put on weight? As E.J. immerses herself in these big questions, her marriage to husband Willis grows increasing strained. Can Pugh solve the mystery around the deaths of Berta and Kerry and save her own marriage?
