Noticed this was the ‘alliteration grid’ again before starting which helped a lot. 1a being (6,7) is a bit of a give away. We’ve previously had county council, get the giggles, secret service, and most recently pyjama parties in the 1a slot and those puzzles all use this grid. Of course it only works when 1a is (6,7) so that the start of the second word is the start of 4d, which is neat.
