A pardon is arranged for the first woman (7)
I believe the answer is:
pandora
'the first woman' is the definition.
(I've seen this before)
'a pardon is arranged' is the wordplay.
'is arranged' indicates an anagram.
'a'+'pardon'='apardon'
'apardon' is an anagram of 'PANDORA'.
'for' acts as a link.
(Other definitions for pandora that I've seen before include "disobedient opener who might have helped 16" , "Handsome red sea bream" , "Girl with box of troubles" , "Possessor of famous box" , "A pardon for the first Greek woman" .)
