Commotion bringing duchy near to ruin (3,3,3)
I believe the answer is:
hue and cry
'commotion' is the definition.
(thesaurus)
'duchy near to ruin' is the wordplay.
'to ruin' indicates an anagram.
'duchy'+'near'='duchynear'
'duchynear' anagrammed gives 'HUE AND CRY'.
'bringing' acts as a link.
(Other definitions for hue and cry that I've seen before include "Stir" , "furore" , "Loud clamour - pursuit of criminal" , "major complaint" , "Public outcry" .)
