I used to think that Listener Numericals were anathema, but now puzzles where you solve all the clues, put the answers in the grid… and then have to delete half of them or more before spending an eternity grid-staring whilst gradually losing the will to live… AARRRGH!!
I started to write a plea for clarification/hints on a whole raft of items, but it got to be embarrassing.
Several people have posted that finding one of the thematic names was the way in to cracking the endgame. I've tried and tried and still no joy.
muraria (#99) gave a hint, but are we talking about the external periphery (as opposed to the internal periphery, i.e. around the central blank area)? And clockwise or anticlockwise?
(Sorry to be so pathetic, but I'm trying to avoid my other half reminding me that I have a life outside crosswords...)
