But why does Gabe seem to be reaching toward the distressed woman — something he had been instructed never to do — as she teeters on the edge, then falls? The dead woman, Amanda, narrates some of the chapters from beyond the grave. She wants to make something clear. The book begins with Margo, an outwardly cheerful librarian with a big secret: In her previous job, she was a nurse with a knack for murdering her patients. With her fake name and new identity, she seems to have gotten away with it.
