The Artist

The team investigate the brutal attack and subsequent death of popular art teacher Abigail Lincoln at the college where she worked. Initial suspicion falls on the college caretaker, who has a conviction for stalking and assaulting a former girlfriend, and with whom Abigail had recently argued. However, it soon transpires that Abigail held information on an inappropriate relationship between a pupil and a member of staff. When headteacher Rory O'Hanlon's fingerprints are found on the weapon used to attack Abigail, it soon transpires that he was having a sexual relationship with pupil Melissa Parker. Jack also discovers O'Hanlon is connected to several unsolved murders.
