Crosophile gets us off and running with a reasonably gentle puzzle
There’s no overt theme but I did rather get a sense of the setter’s indignation over a big orange baby coming to town.
Any resemblance to anyone living or dead is purely accidental…

Across

We struggled a bit with this but got there in the end. LOI was GANGRENED when we happened to find in Chambers that ‘gangrene’ can be a verb. We also had difficulty parsing 15/20, although the answer came easily enough from crossing letters.
Favourite was OGLE for the smile the stunted moose caused us.
Thanks, Crosophile and flashling.
I did this just after midnight, and very enjoyable too. No qualms and I’m sure others will have felt the same. Maybe that explains the lack of comments. Thanks to S&B
There IS a nina, and i t’s not meant to be Trump – although ‘orange’ is a part of it.
@3. I suppose the central clueing is key to the nina. I’d never have spotted it if you hadn’t posted. Original, to say the least.
I still don’t see it.
Nor I.
Too many Rs in 18D, it’s B + RAINIER.
Thanks to Crosophile and flashling.
This is a bit late, but for the sake of completeness I think the theme (not a nina) is colours of the rainbow, though most are incomplete or homophonic and I couldn’t find yellow. RED at 4A, ORANG at 2D, GREE at 25A, BLOO at 22D, INDIG at 11A, VIOLATE at 27A.
Sorry everybody, Even later getting back here! [I forgot!]
Thanks very much , flashling, for the blog – and I enjoyed the Trumpology even if I’d not intended it! 🙂
Well done, endwether and Tatrasman, finding the nina. The key was ‘Artificial colourings’ exemplified by READY, ORANDutan, MUSTERED [I couldn’t find a suitable yellow], ganGRENEd, BLOOms, INDIGnant and [the one that started the idea in my head] inVIOLATE.
Thanks, all, for comments.
Thanks crosophile for confirming the nina – it was charybdis who alerted us to it. Surely the placing of the ‘e’ next to ‘orang’ and the ‘o’i under ‘indig’ wasn’t coincidental? It was that which convinced me to look further.
@Endwether Charybdis is the Superman like alter-ego of Crosophile….
@10 – That’s the trouble with having a split personality. I meant to post as Crosophile at #3!
