Author's representation of corrupt males (6,6)
I believe the answer is:
'author's' is the definition.
(Marcel Proust is an example)
'representation of corrupt males' is the wordplay.
'representation of' indicates an anagram (I've seen this in other clues).
'corruptmales' is an anagram of 'MARCEL PROUST'.
(Other definitions for marcel proust that I've seen before include "novelist" , "Corrupt males (anag) -- French author" .)
