Thanks to Paul for an exceptionally difficult but rewarding Prize this week.
FOI 17 (first scan was not encouraging). I got two long multi-word anagrams (hint) quickly, which was auspicious, but almost all the rest was a struggle.
Several unfamiliar terms had to be deduced from parsing, including an absolutely brilliant trademark Pauline entry.
LOI: tie between (4,24) and 22d, two I doubted I'd ever get.
COD: tie between (20,10), (4,24) and 14d (tricky misdirect). Long COD list included 3, 9, 12, 15, 17, 19 and 23a (yeah, good job by Paul).
I hope other solvers enjoy the puzzle as much as I did, but find it a bit easier 😊. Could be a busy thread.
