Man Comics #27

The teens are in school, in a class taught by Prof. Paul Klein, a German who had been sent to a concentration camp by the Nazis during WWII. Invited to Prof. Klein's house for tea after school, the group meets his nephew Kurt. While they are there, Bob's father arrives on business for the U.N. Security Police. He tells Prof. Klein that many Nazis escaped capture after the war and were working together to once again threaten civilization, under the leadership of the Faceless Man. Mr. Brant believes Prof. Klein is in danger, because the Faceless Man was once heard to say that Prof. Klein was the only man alive who had ever seen his face. Prof. Klein protests that he has no idea what that could mean and declines protection. The professor is soon captured by the Faceless Man and his neo-Nazis, and taken to an abandoned subway branch. Bob and the Troubleshooters follow, and learn that the neo-Nazis plan to dynamite all the pipes and cables running under the city, bringing it to its knees; in the confusion, they will rise up and seize power. The boys attack the conspirators, rescuing the professor and revealing that the Faceless Man was actually his nephew Kurt.
