Hotie here.
All done by 9:30 this morning (Sunday) - all in my own shrunken head - no cheats, no lookups.
Had a bit of a blank-out with the extreme top left and right corners, but worried them out eventually. 'We will chase them like Rats across the Tundra!'
(thats not a cryptic clue...)
Feeling of satisfaction, but what do I do with the rest of the week? The Listener makes my brain hurt these days, and sudoku is REALLY pointless.
