Thanks to (debutant?) Hugo. I found this difficult, though I'm often intimidated by new setters, took a long time to finish.
Hugo definitely has a naughty (Pauline) side, and this puzzle contained arcane GK from both sides of the pond, so I'm not sure of his nationality. Agreed on seeing more of him.
FOI 11. LOI 4, which took forever and probably doubled solving time net of setting the puzzle aside for a while. Not certain of 24d: there are two plausible options but one fits my parsing attempt better.
COD tie between 4 and 2. Enjoyed a great many other clues: 21, 14, 18, 9, 7, 16 and 19. Plenty of complex and witty wordplay.
