He'd rob a distressed girl (7)
I believe the answer is:
deborah
'girl' is the definition.
'he'd rob a distressed' is the wordplay.
'distressed' indicates an anagram.
'hed'+'rob'+'a'='hedroba'
'hedroba' anagrammed gives 'DEBORAH'.
(Other definitions for deborah that I've seen before include "Judge" , "Girl" , "Handel work; girl's name" , "Biblical prophetess" , "Deb's full name" .)
