We blitzed through this a while back! It was REALLY good. I also totally loved Anna Maxwell Martin and her jousting with Damien Lewis. It's a shame it got buried -- I think it was made by some British streaming channel that went out of business, and bounced around awhile without being picked up.

I thought of the Abandoned Friendship Umbrella as being a twist on when Karla drops Ann's lighter that he picked up from Smiley all those decades before, when Smiley finally gets him. The Abandoned Friendship Umbrella is so much pissier, though!
