Former book editor Susan Ryeland is in Crete, running a struggling hotel with her partner Andreas when a couple arrive and ask Susan for help finding their missing daughter. They believe her disappearance is connected to a murder which happened at their own hotel in England as well as the Alan Conway novel that was inspired by the case.

Susan checks into the Treherne's hotel and meets Lisa, Cecily's sister and Aiden, Cecily's husband. As she investigates she learns more from the hotel night manage and spa manager, both of whom indicate that former employee Stefan was correctly found guilty in the murder of Frank Parris.

Susan decides to go to London to investigate what Alan Conway knew about the Frank Parris murder. DS Locke catches up with Susan and warns her to stay away from the case.

Susan meets with Alan's ex-partner, who tells her that Alan knew Frank quite well. He also tells Susan that Frank had a relationship with a sex worker named Leo which could be a clue.

The Endicotts reveal that Martin Webster had a motive to kill Cecily. Liam Corby tells Susan that that he knows a secret of Lisa's. Susan's sister reminds her that Andreas loves her, and what a good pair they make.
