Thanks to Philistine for this week's Prize. I enjoyed it and rate it slightly above Paul's Prize from last week, due to fewer weak clues.
On the challenging side. A number of non-obvious (IMO) anagrams which took time to identify anagrist and anagrind.
FOI 19, motivated by the many clues linking there. Figured out the theme quickly (though first guess was slightly off), but still had difficulty with a few thematic clues.
One unfamiliar word required Google.
LOI 5.
COD 3, with some misgivings (omitted to avoid spoilers); 19d a very close runner-up despite being second one in. Also liked 13a, 10, 14, 22d, 23 and 12.
Enjoy and good luck! There should be enough tricky clues to generate a reasonable number of inquiries.
