Revelation, beautiful woman (9)
I believe the answer is:
bombshell
'revelation' is the definition.
(thesaurus)
'beautiful woman' is the wordplay.
I cannot really understand how this works, but
'woman' could be 'shell' and 'shell' is found within the answer.
The remaining letters 'bomb' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bombshell that I've seen before include "Sudden disappointment" , "Piece of devastating news" , "big disappointment" , "Unpleasant surprise" , "attractive blonde" .)
