Doctor Eternity

Congressman Barlow and his "anti- Nazi committee" are making things too hot for Mr. Schultz and the local Washington Nazis, so Barlow is invited to meet with "Dr. Eternity, Spiritual Guide" -- i.e., medium. The ghost of Barlow's brother predicts Barlow's death. Cap and Bucky are passing by and find a vault under the house, where Eternity and his hunchbacked servant seal them in. They are rescued by another client of Dr. E's and unmask the Doctor to reveal "one of Hitler's star boys!" Source
