Chris Capuano is dead.
Well, murdered to be precise. When Kate Capuano, a Boston doctor, wakes up to the news that her husband of five years has been pushed from the window of an office building, she thinks that's the worst of it. That is until she meets Lucy Marchand, his fiancé.
With the police focusing on a convenient scorned woman narrative for the murder, Kate and Lucy decide to team up to untangle a web of affairs, blackmail, and shady financial transactions, and to find comfort in each other.
But you're supposed to hate the other woman, right? Not fall in love with her. Especially not when she very well could be the killer you're looking for.
