Cast for season 15, episode 51 "Ring-a-Ring O'Roses"

Ackland and Meadows go to visit a woman who has been making funny phone calls to a victim, but arrive to find her badly beaten and the words 'Join the Club' written on her back. The attack is linked to a similar attack on a prostitute, and as other local toms offer information, Ackland discovers that 'Join the Club' is a synonym for the attacker deliberately infecting them with HIV. As he attempts to carry out another attack, Quinnan and Rickman pursue him into the night, and finally manage to bring him into custody. He refuses to give his name, but Rawton recognizes him to be an ex-lover, Andy Marshall. When Ackland reveals what he has been arrested for, Rawton realises she might have been infected.

90-minute special, James Thornton guest stars.
