We're back and in the same physical location for ONE WEEK ONLY, so the only sensible thing to do is talk about a spy book from the 1980s. What was "Spycatcher"? What secrets did it contain? How did it manage to leave Margaret Thatcher "shattered"? Was that a typo and she meant "sharted"? Sorry, we didn't get enough juvenile humour into the episode and it has to go somewhere.
