12. The Untouchables

DC Danny Glaze sees a man set alight on the Larkmead Estate, and becomes determined to solve the case. They identify a suspect's car from CCTV tapes, and Insp. Monroe discovers a witness to the incident, a girl named Rochelle, who identifies the suspect, Dominic Mileham in a identity parade. When she suddenly retracts her statement and accuses Danny of paying her to identify Mileham, it seems Mileham and his solicitor father will go free. Danny takes a big risk and convinces Rochelle to wear a wire to prove Mileham's involvement.
