Hi PezBuin - I'm sorry I missed your earlier request directed to me - I've been in front of the other box! You seem to have all the poets now - I'd never heard of Empson either - found him on a list. Hope you've got the lot.
Only one clue left and would love to finish it:
18A Black as the one who was jailed in America?
(-R-S- B-R-N)
And could you please explain why - I'm fairly new to cryptic puzzles!
Many thanks
Heather
I made that one "Press Baron" (referring to Conrad Black). I don't know if there is any clever wordplay. I think it's just a tongue in cheek definition.
