Deceptive woman is overturning victory (7)
I believe the answer is:
evasive
'deceptive' is the definition.
(thesaurus)
'woman is overturning victory' is the wordplay.
'woman' becomes 'eva' (woman's name).
'overturning' says the letters should be written backwards.
'victory' becomes 'VE' (VE is short for Victory in Europe).
'is' in reverse letter order is 'si'.
'eva'+'si'+'ve'='EVASIVE'
(Other definitions for evasive that I've seen before include "Difficult to pin down" , "Shifty; equivocating" , "Hard to catch" , "Avoiding self-revelation" , "make out-of-the-way sort of action" .)
