Fine story to be rewritten? Cool (6)
I believe the answer is:
frosty
'cool' is the definition.
(thesaurus)
'fine story to be rewritten?' is the wordplay.
'fine' becomes 'f' (abbreviation).
'to be rewritten?' is an anagram indicator (I've seen 'being rewritten' mean this).
'story' with letters rearranged gives 'rosty'.
'f'+'rosty'='FROSTY'
(Other definitions for frosty that I've seen before include "Lacking in warmth" , "Icy cold" , "Cold and unfriendly (glance or reception?)" , "Chilly in attitude, like musical snowman" , "showing little enthusiasm" .)
