A novelist and his rude novel (7)
I believe the answer is:
rushdie
'a novelist' is the definition.
(I've seen this before)
'his rude novel' is the wordplay.
'novel' indicates anagramming the letters (letters in a new or novel order).
'his'+'rude'='hisrude'
'hisrude' is an anagram of 'RUSHDIE'.
'and' is the link.
(Other definitions for rushdie that I've seen before include "'Salman ..., author (7)'" , "See 23 Across. 23 and 22 Across: Author under Islamic sentence of death for blasphemy" , "Salman -, Midnight's Children author" , "Salman, writer" , "Salman --, novelist" .)
