Devadolly,
Herself has been her monopolising the loptap, for her genealogy stuff she cannot do at work during the week, and she doesn't have internet access at the flat in London!She arrived thursday evening (that minus a meadow= 40a). She left this afternoon, I was allowed limited access on sunday as she appreciates my need to N&C on EV! So no need to worry about moi! You can't keep a good Establishment Person down in the long term, or even the short term come to that!!
OK, let's see if I can help a little more. The 11 letter word ends with an N! 31d has all the letters of the last 4 letters of the 11 letter word, fortunately all of 31d are checked! That should give you the 5 anagrams you need. Look at my post in response to Novalis, Ginger Tom wouldn't 20a if Rover did a modified 8d, 9d or 39a! The latter could also be a covering for a tree. That should guide you to a 3 letter word in the middle of the 11 letter word, adapted in the same way as 8&9d and 39a!
Glad you ate well in the House, have not fed there formally, but have been to receptions though with drinks and nibbles(?) on the terrace.
If you are struggling with other answers that intersect 31d, just ask!
