Looking for a movie!

Hi all,
[i] saw some of a movie once that [i] want to watch but cant remember the title. [i]t was called somthing like, ‘‘is there a time to kill’’ ‘‘have we the right to kill.’’ or somthing like that. [i]f [i] remember right it was about a female spy or detective and it was set in ww2 Europe, probably made in the 40s or 50s. Anyone know what its called or who made it?? Thanks!

Not sure if this will help:
