Reluctantly joining forces, Cleo and Harry realize the wrong person was targeted, but the police think they have their killer and refuse to look elsewhere. Taking on the investigation themselves, they peel back the lies and expose the sordid details of a marriage in tatters, and see firsthand how gossip and politics fuel the machinations of high society. Meanwhile, at the Mayfair Hotel, expansion plans are on the menu, causing tensions to heat up in the kitchen between the chef and Cleo's uncle.
