Despite the theme, I found the clues more difficult than the average Prize. I only got 9 by assuming it was thematic and looking up the presumed entry in Chambers. And still I needed geeker’s help to parse. Thanks for that, geeker. I had never heard of 20, so thanks again to geeker for showing me the way. I should have enjoyed this given the theme, but some of the clueing seemed really tortured. COD the combination of 26 across and down. Clever to put them together.
