Hmm. All done, grid filled, curve drawn (rather fittingly today), messages complete and the final word worked out.
However, I don't think I've finished a puzzle with so much unparsed before ie 14a, 22a, 27a, 46a. Strangely, no problems with the down clues.
PS The solver on this site has the 'random word' as it is here. If you work out the middle letter of the 5 and put just that in I expected to get pages and pages, but no. I had a shrewd idea what I was looking for and lo!
