"Mirror, Mirror" is a mystery story with two parallel tales. One tale covers a century. It is the history of the Tremble's, Roger's family. It gives a graphic insight into the psyche of 'Roger' the serial killer. The other tale covers the timeframe of a week. It follows Inspector Georgina Borg's pursuit of a serial killer. She has been unable to crack the killer's identity. The murders have been over a period of ten years. She has followed the trail from Sydney to Melbourne. All of the victims have been loners or with distant family and without husband and especially kids. Cate, the last victim, however has a different profile entirely. Borg knows it is the same killer, but why this change of modus operandi? She feels that this will be the killer's downfall. Borg is convinced that latest victim may complete and solve the serial killers puzzle and reveal his identity. In the meantime Borg's life is an emotional mess. She is unable to commit herself to a permanent relationship with Professor Richard Thompson, but is madly in love with him. During her investigations into the latest killing, Richard becomes a prime suspect! The two stories reflect upon each other and finally, in a macabre twist, come together. Georgina is then faced with a race against time to try and stop her now 'revealed' killer from leaving her precinct, and perhaps eluding the clutches of the law forever.
