A pure work of art, absolutely brilliant. That's how I would describe the new episodes of BBC drama series Spooks, of which series 6 started last week on BBC1.
The first story spans the first two episodes. In the first episode, a threat of a fast spreading lethal virus in London is introduced. In the second episode it gets even more harsh, when MI5 decides to abduct spies of befriended nations like USA, Russia and France and threats to infect them with the virus, to persuade them to reveal the location of the antidote. MI5 believes one of those nations manufactured the virus and must have produced an antidote as well, but are certain the only way to get them to admit this antidote exists, is by these extreme measures.
In the end the antidote is found and all infected victims are cured, but relations with intelligence services of befriended nations are very hostile because of the abduction. And this will most definitely dominate the storyline of the next episodes. I'm really looking forward to it.
