Cadi interviews the prime suspect in the double murder, and finalises plans for her move to Liverpool.
It's been a decent series, but for me it hasn't, up until this point, sparked into life, I was hoping that this series finale, and indeed show finale would end on a high, and it does.
This was such a satisfying conclusion, nothing felt vague or ambiguous, every loose strand seemed to be tied, I wasn't left with any unanswered questions, a very sad story.
This was as much about Cadi, as it was about the crime itself, we got to see a very different side to her, a much kinder, softer side, we've not seen that over the last three series.
I have to say Sion Ifan was once again utterly brilliant, the scenes between him and Glyn, him and Cadi were incredibly good, I had a tear in my eye on two occasions.
A shame it had to come to an end here, hopefully that's a decision that will be reversed.
9/10.
