Miserable place for dancing -- last one awful (12)
I believe the answer is:
disconsolate
'miserable' is the definition.
(thesaurus)
'place for dancing last one awful' is the wordplay.
'place for dancing' becomes 'disco'.
'awful' is an anagram indicator.
'last'+'one'='lastone'
'lastone' with letters rearranged gives 'nsolate'.
'disco'+'nsolate'='DISCONSOLATE'
(Other definitions for disconsolate that I've seen before include "Unhappy and impossible to comfort" , "Very sad or disappointed" , "Unhappy and unable to be comforted" , "Melancholy" , "Dejected" .)
