She's found in Aden - drunk (4)
I believe the answer is:
edna
'she's' is the definition.
(I've seen this before)
'aden drunk' is the wordplay.
'drunk' is an anagram indicator.
'aden' anagrammed gives 'EDNA'.
'found in' acts as a link.
(Other definitions for edna that I've seen before include "Female Dane, oddly" , ". . . . O'Brien, ... Saint Vincent Millay" , "Barry Humphries' Dame" , "- O'Brien, Irish writer" , "Prolific Irish woman novelist . . . . O'Brien" .)
