Trial & Retribution

James McCready has served eight years of a life sentence for the murder of his partner, Gary Meadows. McCready has always claimed that the stabbing was a tragic accident and that the police inquiry, led by Det. Supt. Michael Walker, was prejudiced. Armed with new evidence, McCready's solicitor, Ben Duffield, and gay barrister and MP, Robert Rylands, join forces to campaign for an appeal.

Meanwhile, DI Pat North is chosen for a new Home Office scheme to fast-track talented detectives. To Walker's annoyance, she is placed on the re-investigation of the Meadows case along with her best friend Vivien. His career is flagging and North's success highlights his inadequacies and their differences. North, concerned about appearing biased, refuses to discuss the case with Walker and tempers fray. When Walker warns Satchell they must get their stories straight about Glasgow it is evident they are covering something up - but what?
