Answering me, they ruffled American author (6,9)
I believe the answer is:
ernest hemingway
'american author' is the definition.
'answering me they ruffled' is the wordplay.
'ruffled' is an anagram indicator.
'answering'+'me'+'they'='answeringmethey'
'answeringmethey' is an anagram of 'ERNEST HEMINGWAY'.
(Other definitions for ernest hemingway that I've seen before include "A new genre is myth (anag) - author" , "Writer" .)
