Nothing like a good scottish accent to give the character some street cred, and it is well carried by Richard Madden who plays the rôle of a seriously messed up war veteran turned cop.

Like 'Line of Duty" it centres on corruption, leaks, political ambition and terrorism within London, where any day someone can blow themselves and the surrounding crowds ........ blow them up without a second thought.

Great acting again with a lot of the principals in 'Line of Duty" showing off their chops in completely different parts.... yet being just as convincing. Keeley Hawes and Gina McKee are just flawless.

This is a plot that demands your complete attention and if you miss a little clue then you'll be lost for a while until they cleverly give you a recap without ruining the storyline.( or on Netflix you can just rewind!)

I love the way they portray the public schoolboy characters with their glib and educated responses, I love the way they show the pols as scheming and amoral vipers and I love the way they show the inside of the homes as they are in day to day life.

If I had one complaint it was that some of the escape hatches they contrived for the plot were a bit hokey and some of the telecoms were too far fetched to believe.

I mean, there's no police force in the world that can be as efficient as that.

Even George W Bush couldn't get through on his phone from Air Force One when the 9/11 attack was unfolding and these guys are getting instantaneous contact with every cop in town and immediate response from databases.

But , if you suspend your logic and tell yourself that this isn't real, then they have licence to play with the truth.

Thoroughly enjoyable, with the writer trying to trick you at every turn.

Watch and see if you fall for those tricks.
