Thanks Geeker.
I had got the wrong guess; now I have the right answer.
I think I have the answer to 24ac but can't parse it. I take it, it is the very Pauline clue meaning bulky, but where is the "brown"?
It is time for my glass of wine now, which may shake out the brain cells for the remaining SW corner, though I still haven't got 4,15 and may have 5d wrong.
Please don't stop posting Geeker. I enjoy all the comments in the Forum even when they are about football or chess.
