Mendes of "Training Day” (3)
I believe the answer is:
eva
'mendes of training day' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eva that I've seen before include "-- Braun, Hitler mistress" , "- - , nee Braun" , "-- Pern" , "Braun or Peron, say" , "Female" .)
