Yet again, problems with both the online and print forms of the Genius Crossword. It would not seem to me too hard to ask the compiler to check over the clues to verify correctness before publication.
Just a few left to get in the SW corner. A hint for 15 would be much appreciated. I have the first and last letters but can't find any word that fits. I also can't parse 19 even though I think my solution is correct.
