Returning home to England from New York, Margot finds her family in chaos. Her cousin Chloe is in prison awaiting trial for murdering her twin sister Claudia, their mother has withdrawn into the imaginary world of her romance novels, Claudia’s fourteen-year-old daughter has regressed to early childhood and refuses to leave her bed, and to top it all off, the family cat has decided to live with the neighbors.

As Chloe’s trial approaches, the atmosphere in the house becomes increasingly fraught, and Margot begins to wonder whether someone else is responsible for Claudia’s death. Is Chloe taking the blame for the family’s sake? It’s not until a second murder that the pieces begin to fall into place and the cat agrees to come home.
