The Quiller Memorandum

You are a secret agent working for the British in Berlin. You are due to go home on leave, but you are being followed-by your own people, or by the enemy. A man meets you in the theater and briefs you on a plot to revive the power of Nazi Germany. You do not believe him, but you remember that one of the suspects mentioned was a senior SS officer you met with in the days when you were working as a spy in Nazi Germany. The next day you make contact with a beautiful girl who may know something. Someone tries to kill both of you.
