In “What the Wife Knew,” accomplished author Darby Kane ably demonstrates her expertise writing about families and relationships. Here we meet several dysfunctional families, but perhaps the most dysfunctional is that of main character Addison. Her mother would clearly win a “Worst Mother of the Year” award, as she is an absolute narcissist who has used Addison her whole life without regard to Addison’s safety or well-being at any time whatsoever. Addison fled when she graduated from high school, but no matter how far she goes and no matter how she tries to stay under the radar, her mother finds her and tries to manipulate her.
