I have to admit I'm struggling with this. Maybe I'm not on Imogen's wavelength today. A few words I didn't know but thankfully parse well, 14d for one, and some that seem a bit loose. I think 16a is going over my head somewhat. Sure I have the right answer but 9a doesn't really read right if I have.
I appreciate some hints have already been given but any other possible nudges for 9a gratefully received.
