Haven't got access to the puzzle as I'm out tonight. But from memory changing the s would produce an a. So 'all of his' becomes a? I can see a' is northern for all, but why 'of his'?
Like others, struggling with SW corner, would love a hint for 29d, I have S?M??
Also I have all crossers for 21a, there must be multiple clashes in this word?
Thanks iratus, got the coin, but don’t see parsing?
I can’t post anymore from my android phone, about two weeks now, can only post from an I-pad. No idea why.
