Audrey I'm sorry if was a bit grumpy yesterday.
I think I've seen hints - if not answers - for 48, but....
L -iberal + revolutionary ( ie anagram) assembly (8 letters) then _ (4 letters)
Because of what immediately follows 'embassy'. K has it immediately following 'then' in his first reply to you. I stress 'immediately'. Hope this will clarify it.
I'm sorry Audrey....it had never occurred to me - until Muffet happily joined in - that you hadn't got it. I'd thought you were giving me line / shop/ room for my information, not as a plea for further help. Thanks Muffet for coming to the rescue!
I think discrete means lots of separate pieces ( that have to be assembled) - as opposed to discreet which _ is ! All very confusing
