Hi Macky. The second creator isn't a poet. The corrections to the down clues include a common 3-letter word for conflict. Then anagram the others and look up the 2-word title on wikipedia.
All done, I hope, but still a slight doubt about one of the cryptic representations to be highlighted. Am I right to think that each set of highlights is made up of consecutive cells ?
Thank you.
woodlouse - I've only just finished the puzzle & the anagram is not the sort of thing one would normally notice. Or look for really. The setter's day job?
