Katie and Stefan barely escape Uncle Fred’s with their lives, and find a clue about the men pursuing them that leads them to Glasgow. In the past, Stefan encounters Katie at another seaside wedding, convinced that he’ll find evidence that Hugo and her aren’t right for each other. But just when he’s about to give up on her, he finds some shocking evidence of what she’s really up to.

Stefan and Katie’s captor interrogates them about what happened on their trip to Las Vegas months earlier — a trip that Stefan thought was an impromptu bachelorette party for her after Mary Delaney bailed on her. But as Katie reveals, she had an ulterior motive that fit into her grand plan, and that put both of their lives in danger…

Katie journeys to London to seek answers from Vince, a tailor to the criminal underworld, while we finally learn the truth about her secret tragedy, and the ten-years-in-the-making revenge plot that it led to. Stefan searches for her in London, but is he ready to forgive her? And can he get to her before The Block do?
