A twisty domestic thriller. When Lucy meets her wealthy, elegant, and controlling mother in law Diana, she is aware that she doesn’t quite measure up. Five years later, Diana is found dead, an apparent suicide, but there is none of the poison from the bottle she is found with in her bloodstream, none of the cancer she mentions in the suicide note, and evidence of suffocation. The novel tells the story of the intervening five years, from multiple points of view, as the killer is revealed.
