I'm feeling under the weather, which I'm using as a excuse for giving up with only about 2/3 done. Another fsctor is that 2,3, and 4 downs were a bit iffy!
However I don't think the Smiley reference is coincidence. If you read "Tinker, Tailor, Soldier, Spy", 10a is the specific person in charge, who sets Smiley the task of sorting out who did it.
