Got the grid filled relatively quickly, but the endgame is escaping me completely, I can't find anything that fits the parameters, so if anyone can give me a nudge, that would be lovely.
After a late start to this, I'm struggling to get on Artix' wavelength. A prompt for 18d would be appreciated: Silly mistake before old commander's order to his ADC? (8, 3 words).
I now realise that wasn't the clue I intended to query (!) though the help is much appreciated. I meant: 18d Archetypal Irishman in street served up seafood delicacies (9).
