Can't remember the name or that much about it. Saw half of this unknown suspense film as a child but the movie was damaged. I have been itching to find out what happens at the end all the years since. What I do know:
Takes place in London during the Blitz in World War II. There is a blonde girl who is running/hiding from a pursuer of some kind. Beginning scenes take place in a bomb shelter in London Tube during air raid. There was a man who may have been a spy and was hiding in cognito as a doctor, but this part is fuzzy in my memory. Likely made in late 1940s/1950s and was in color.
_Any_ information/guesses/hints would be greatly appreciated!
