Señora Perón (3)
I believe the answer is:
eva
'senora peron' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eva that I've seen before include "- Braun, Hitler's mistress" , "Braun or Peron, say" , "- - , nee Braun" , "Girl's name; space walk" , "-- Cassidy, singer, 1963-96" .)
