Many thanks to up-and-coming Prize favo(u)rite Brockwell for a brilliant entertainment this week.
I think I've spotted a trademark theme, but need more time to consider subtleties.
Solving time around Prize norm, but plenty of wit and challenging clues to make the puzzle enjoyable.
FOI 1d, LOI 27 (which greatly extended solving time and required Google assistance given crossers).
Too many delightful clues to rank a COD. The long list is (in rough order of solving) 11, 4, 8, 7, 14, 25, 21, 17 (nice surface), 18 and 27. I slightly prefer 8 and 11 due to personal interests but can't "objectively" rank them above the rest.
Well done, Brockwell.
