Writers of TV lines, so absurd (9)
I believe the answer is:
novelists
'writers' is the definition.
(novelist is a kind of writer)
'tv lines so absurd' is the wordplay.
'absurd' is an anagram indicator.
'tv'+'lines'+'so'='tvlinesso'
'tvlinesso' anagrammed gives 'NOVELISTS'.
'of' acts as a link.
(Other definitions for novelists that I've seen before include "authors" , "Writers" , "read their stories!" .)
