My last entry is 19 Across, and I have all but the unchecked letter. All I can come up with for the word required is the last word in the title of a book by Jerome K Jerome, but I'm at a loss to justify this with a Malapropism, especially one that fits the "clue". As others have pointed out, some of these "clues" are quite loose. In my opinion too loose. Can anybody give me a nudge without giving the game away?
