Harry goes off to see an old spy, who turns out to be up to something, whilst nodding off over some Soviet literature… Selectric gets a nice bit of product placement, too!
There’s also a shot of the military college in Greenwich later on, I think.
Of course the official site doesn’t go into any of the references mentioned in the episode, such as the mysterious “How to Get 165 Eggs from Every Chicken” alluded to in the Blackheath scene. Where is the director’s podcast commentary, like in BSG?!
