One v all represented in creative work? (7)
I believe the answer is:
novella
'creative work?' is the definition.
(novella is a type of literary work)
'one v all represented' is the wordplay.
'represented' indicates anagramming the letters.
'one'+'v'+'all'='onevall'
'onevall' anagrammed gives 'NOVELLA'.
'in' is the link.
(Other definitions for novella that I've seen before include "short book" , "Short fictional work" , "Slim volume of fiction" , "Composition" , "Slim work of fiction" .)
