Isn't love misrepresented by this writer? (8)
I believe the answer is:
novelist
'this writer?' is the definition.
(novelist is a kind of writer)
'isn't love misrepresented' is the wordplay.
'misrepresented' indicates anagramming the letters.
'isnt'+'love'='isntlove'
'isntlove' anagrammed gives 'NOVELIST'.
'by' is the link.
(Other definitions for novelist that I've seen before include "King maybe" , "I've written" , "Writer of fiction books" , "Writer of long stories" , "Author" .)
