I have been thinking like mad about question 14 and although I can get anagrams of 49, none of them mean against or have anything to do with 'up in the air'. Thanks calliewag for your suggestion but I cant make sense of that either especially as the roman numerals for 49 are XLIX !! Am I being particularly obtuse ??
38. The first listener turned around very quietly and last pluck was painful (7,5)
44. Special agent given a light airing post-war (4,6)
52. Safety pin joins first hair to the toupee in front of the fire. (6,3)
Sorry to be asking for more clues !! Many thanks.
