Overwhelmed by greed, I tormented journalist (6)
I believe the answer is:
editor
'journalist' is the definition.
(senior journalist)
'overwhelmed by greed i tormented' is the wordplay.
'overwhelmed by' indicates a hidden word (the clue has absorbed or overwhelmed the answer).
'EDITOR' is hidden within 'greed i tormented'.
(Other definitions for editor that I've seen before include "Journalist in charge of publication" , "Ted or I could bring out a newspaper" , "Head of a newspaper say" , "Newsman" , "One working on paper" .)
