Last in the series for the British take on 'Law and Order' tonight will see Ronnie and Joe still reeling from the death of one of their own. At the same time facing into a case where an innocent young mum is fatally stabbed in a busy marketplace, just as a senior police officer publicly pledges to crack down on knife crime. The pair are under pressure from both sides as they struggle to gather evidence against the youth they think is responsible. Ronnie manages to get a confession out of him, but is the only one who hears it and struggles to get anyone to believe him. Eh, surely the Detective Sergeant has proved his word is good by now? That's out of order, out of Law and order.... sorry.
