An excellent series, all the actors were so good and convincing in their roles. The two lead detectives were likeable and believable. Their home lives were satisfactorily ordinary, with the kind of life challenges most of us face, such a relief not to have very damaged police officers as so often is a plot device.
My daughter announced last week that the three suspects had killed each others abusers, so they all had cast iron alibi's. I didn't find the ending unacceptable. The lead detective had been told several times to put the case away, to be reviewed in a couple of years by the cold case team. As for them being 'judge and jury' that isn't unheard of. Their analysis was fair and accurate, these three victims had survived and all gone on to live productive lives in which they tried to help others. They didn't post a risk to anyone, would not offend again. The cost of a trial and imprisonment would be huge so the public interest as served by closing the case. I just hope the Nicola Walker character destroyed anything that would help the cold case team.
I was shouting at the tv for them to tell the gay male character because I feared suicide was possible for him.
