20 down One admitted to infernal double negative? N?R?H?R - only word I can come up with is NORTHER (a wind) but don't get the connection. Would much appreciate assistance!
Thank you Lie-in King. However the R came from Theory (the relative proposition) for which I had the letters T?E??? and could only get Theory - that is now T?H?I? which I would reckon is THEIR but don't get the parsing!
