[spoilers] Sir Harry Pearce 2.0

[Silktie]

Yeah, I'm still not really satisfied with that explanation, and think it rather falls into the category of 'dramatic license'. The only legitimate reason I can think of for Harry to be involved is if he had some Russian contacts that could be exploited for the operation, but the only connection he has with Russia is his debriefings of that old geezer who was a Russian spy and was released from jail in season 4. So I don't see it. It's the same with the question of what Lucas was doing in Russia when he was captured, seeing as he was MI5 and not MI6 at the time.
