Actress Foch (4)
I believe the answer is:
nina
'actress foch' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nina that I've seen before include "Girl" , "hidden crossword message" , "Al Hirschfeld's 'hidden' daughter" , "- - Simone, 1933-2003, singer" , "- Simone, US singer" .)
