Suspects

Martha, Jack and Charlie investigate the case of a missing soldier, who went to the pub with his army mates a week ago and never came back. Has Pete’s PTSD pushed him over the edge and out into no man’s land, or has something sinister happened to him?

When an ex-con is found beaten and stabbed in a copycat crime, suspicion falls on the family of his victim. Martha, Jack and Charlie need to uncover the truth behind the historic investigation in order to crack today’s case.

Martha and her team are shocked by the shooting of a popular clergyman in broad daylight, outside the boxing club he runs for disaffected youths. The D.I. suspects the vicar’s hug-a-hoodie approach has backfired--but the investigation soon moves into far darker territory.

Martha’s disgusted by a brutal attack on an elderly widow in her own home, and charges Jack and Charlie with finding the culprits. The thieves have taken the old lady’s life savings and left her critically ill in hospital--can the team catch the scumbags who did this?
