Spoilers if you aint seen the end.

 

So The Caddy was revealed to AC-12 in a long drawn out but thoroughly entertaining gripping drama that had most of us saying how long can this go on for.  In a way though the timing was brilliant, it was n't over long and each scene was tense. We were left with all the answers we needed and an ending which brought the series to a satisfying conclusion.

With the story starting with the arrest of Arnott and moving onto his interrogation Line of Duty was setting us up for a episode in three acts.  Cottans turning all the evidence on Arnott with Hastings seemingly backing him up.  Act 2 was Kate Fleming going by her hunches that something was n't right and getting all the evidence in the background to bring The Caddy to justice.  Act 3 was the getaway and the end for Cottan.  

The interrogation scenes were fantastic, tense, and mesmerising.  Hats off to  Adrian Dunbar, whose Hastings 'fella' and 'son', comments were at times funny and very sarcastic.  He was the boss throughout who just fought for justice and was un-corruptable even in the earlier episodes.  Arnott under fire just could not get the upper hand on Cottan and it was a master stroke of writing that Kate was the hero.  Lets also not forget WPC Bindra who I thought was going to be bumped off.

It seemed for a short time with the news there is a series 4 to be made that Cottan would escape.  With the chase sequence and Kate going through the streets of Belfast, where Line of Duty is filmed, hanging onto a lorry was Cottan going to get caught.  Kate and Matthew speaking , when the viewer was thinking just shoot him or wound him, but Cottan's cohorts turned up.  It looked like Cottan had got away.  If he had got away I think a lot of viewers would have been unhappy with that outcome.  In the end Cottan got killed saving Kate from a villain's bullet and Cottan gave a dying mans statement.  It was unlikely he would have ever killed Kate, he had a romantic notion towards her that was possibly never to be returned.  With his dying breaths he gave a statement for the police to use as evidence. 

The bad people got there comeuppance, the good ladies and gentlemen also were rewarded.   Denton was the one you felt sorry for the unmarked grave, the paupers funeral.  Surely she should have got full pardon and a police funeral of some sort.

Line of Duty is over til series 4 comes out , a long time a way I'd imagine.  It's been great drama, well written and extremely well acted.  All of the people in it have given top drawer performances and I'm sure many a viewer will be returning to watch the 3 series in their entirety.
