Despite being the daughter of a famous journalist, Fiona's career and life have very much been on hold since the murder of her older sister 20 years before. Her sister's body was found on the grounds of a defunct girl's boarding school, Idlewild. A man is in prison for the murder, but Fiona still has questions and can't let it go. Even her relationship with Jamie Creel, the police chief, and son of the chief who investigated her sister's murder is hampered by her questions and emotional distance.
