Spooks is a bit of an institution; superb propaganda for Blighty's secret service whilst also totally preposterous, tense, dramatic and highly entertaining all at once. This final series (a paltry six episodes, sadly) was the Harry and Ruth show as revelations of HP's murky past in Berlin come to the fore and Ruth questions her trust in the man who can barely trust himself.
Fittingly, for the series swansong, it's back to Cold War type as the Russians come to town looking to seal a bi-partisan information sharing deal, one that the CIA soon get wind of and find as appetising as a glass of warm Bud. The waters are further muddied by the Russian minister's wife, the fragrant Elena Gavrick with whom Harry shared his own "special relationship" all those years ago. He is totally compromised and begins to doubt the Americans with devastating consequences for everyone concerned.
The running storyline is top notch in this however the casting of the other agents is weak - no Roz Myers or Lucas North when you need one. This lot look like estate agents with toy guns, definitely out of their depth unfortunately with the producers relying on unlikely James Bond-like tech wizardry to do much of the instant "spooking" for them. No signal problems for these guys, even in the bowels of the American embassy and their "apps" run perfectly at all times. Some of the set pieces are a bit daft too but rubbish supporting roles aside, Ruth and Hazza still rule the roost and our old friend from the sea coming back to "mop up" in Moscow was a master stroke at the typically unhappy end.
