I think I must be doing a different crossword lol. I have a full grid apart from 9d and 22d, and 35a. My removed letters is partly garbled (from 23a to 26a) and partly blank 27a-35a mostly and 9d-28d mostly) because I could not tell what letters are missing lol. I have no idea what three letter word could go in the middle, nothing makes any sense, and neither do any of the gentle hints in this thread.
Having said that, I dont usually get this close to finishing so am pleased so far!!
