Green of "Casino Royale" (3)
I believe the answer is:
eva
'green of casino royale' 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, Brick or Peron" , "Dame - - Turner, soprano" , "Miss Peron, perhaps" , "Dame - - Turner, 15" , "Girl's name; space walk" .)
