well, i now have an answer for each, but i'm not at all sure about quisling's favourite, 6. i certainly can't parse my answer. (i assume the anagram of a boxer is coincidental?)
jono, are you sure about 12? Unless I am missing something, based on the sources I have found the answer, rather than missing "love at first", seems to be missing "hate at first" instead.
Good one, Jono! I thought I might be losing my marbles when I could only see about 4 answers last night. It would have helped if #1 had been one of them :) Quite a relief when the penny dropped this morning.
#6 was my last in, and raised a smile also.
On first read-through, solved #1, 4,5,9,13,14,15 and the theme emerging.
I am busy next few days, and may solve more, but doubtful. Happy New Year. It has to be better than my last one 🥳
