3x3 - Touching Evil

A serial killer who is burning the bodies of his victims to a crisp is operating in Ellendon. Meanwhile, Enwright introduces junior DC Martin Simmons to the team, much to the dismay of Creegan, who takes an instant dislike to him. As another victim of the killer turns up, Creegan realises that all of the murders are linked to a psychiatric hospital which burnt to the ground in 1989.
