This captures first female robbers (7)
I believe the answer is:
thieves
'robbers' is the definition.
(I've seen this before)
'this captures first female' is the wordplay.
'captures' indicates putting letters inside.
'first female' becomes 'eve' (in the Bible).
'this' placed around 'eve' is 'THIEVES'.
(Other definitions for thieves that I've seen before include "robber" , "Robbers" , "They may be thick" , "Stealers" , "Pilferers" .)
