Overview
The identity of the man trying to kill June Ackland may be revealed when an ex-Army officer is overheard boasting that he was paid to ""kill a copper"". CID link him to a young man who committed suicide in prison after Ackland arrested him for dealing drugs on the Jasmine Allen. WDS Jo Morgan realises that their witness, Mrs Cooper, is behind the plan as she turns out to be the mother of the dead boy. Mrs Cooper is arrested for conspiracy to murder, and she reveals that the assassin is lying in wait for Ackland at the safe house. As Ackland and an SO1 team head off to the safe house to draw the killer out, they are ambushed by a man on a motorbike just outside the station, and Jo Morgan is killed in a hail of gunfire as she rushes to warn them.
