But when two armed, masked men burst into a conference room one lunchtime, kidnapping a trainee and a partner, Maddy's life is plunged into disarray once more - particularly when charismatic DCI Jake Carver, who caught a heartless killer when they last met and with whom Maddy shared a mutual chemistry, is called to the scene. Things become more complicated when a disturbing video reveals two more trainees have been taken. What initially appears as a random kidnapping for mercenary gain soon evolves into something far more complex, the horrifying events of 30 years ago motivating the abductors and having colossal implications?
