A couple of hours in and I have the first and last acrosses entered and 7 others cold solved. No idea yet about the endgame. At this stage, the effort/reward ratio feels rather discouraging.
ja - how have you managed to enter the first (or last) across - my reading of first sentence of preamble meant that you wouldnt know where 1 across starts?
I have 18 solved - and most of the thematic adjustments to the remaining clues, and still am struggling to progress, and have a blank grid!
I don’t know if the last entry is definitely correctly entered, particularly as it could well describe a different method of entry. Just taking a punt in a rather desperate effort to convince myself that it’s worth carrying on.
I would be grateful for help with 2d and 4d
2d Look! Songbird nibbled court summons (7)
4d My name is something old-fashioned (4)
I have solved a lot of clues but I can't fit them into the grid
