my best guess is it's either "kiss king" inside "trouble" for an answer meaning "ring", or "kiss" inside "trouble" for an answer meaning "king's ring"
apparently none of the named rings in LOTR are 9 letters long
"(in) trouble" could be an anagram indicator but qat knows no one-word anagrams of "kiss king's"

I can give a hint for the C4 if one's wanted, but I'm not sure what sort of hint would be useful. It's a pretty short clue so giving information about how the wordplay works seems like it might be more information than wanted. (I dunno, maybe everyone just wants it out of the way :-).) I could give a letter, or say something about the structure of the clue. Or nothing at all, of course. Preferences?
