Came to this very late (Mon 21st March) and should just about get it to St. Albans in time if 1st class post works. I found it a bit of a slog, but eventually got the instruction. 7th word was a good hint as to what to do to the puzzle's heading. Then not difficult to identify within the grid which 6th word needed to be 7th, 8th, 9th word.
Once again I'm very grateful that I didn't look at this thread until I'd finished. Gertrude Stein? Bollywood? What are you lot on about? 90% of what was being written on the thread was totally irrelevant once you'd got the missing / extra letter instructions, surely? It couldn't have hinted more heavily at the overall theme, so the tutting at Speravi was a bit pointless, I thought. If I'd read the thread before starting, I don't think I'd have started at all or got anywhere near finishing, so the policy of not giving too much away is definitely working. I agree on the figure of 9 "components".
