Grid completed; trick worked out (a masterpiece of setting, to get all those "Xs" in (where X = something else)). But completely baffled by the clues to 6,5 which has to be written underneath. Does the break between the two clues occur after 15?
Heavy hint on the other site - it's from the Latin mass.
First clue is 3+3+4+1
Second clue is anagram of Sad rumours c
I would never have got this without the hint...
I've looked at the Answerbank site and I cannot see any hint at all, never mind a heavy one - just a query about the extra word in 10a.
I thought the second one might be that anagram but it didn't suggest anything to me. I'll take a harder look.
1246 - I should have known! But thanks anyway, bobbibunny. I found it in the Oxford Book of Quotations under "The Missal". A disappointing end game there - are we supposed to know all the words of the Latin mass now?
