I really enjoyed that, thank you Artix. My favourite Listeners involve learning something new and this one triggered some interesting reading around the theme.
I have some loose ends to tie up, as usual:
1. I'm not entirely comfortable with the wordplay for 2d.
2. I'm not convinced by the use of the fifth word (dear) in 17d. BRB doesn't seem to back this up.
3. I've a niggling feeling that the final result of the final instruction should be thematic but I can't see how. Is it?
Please can someone who is cleverer than me put me out of my misery?
