History

Fritz von Bock disguised as Dr Noon
When he attempted to do so at the home of Colonel Tarley, the screams from Tarley's wife attracted the attention of the Angel. Turned away because of the quarantine notice and policeman on the door, the Angel instead began to track down Dr. Noon, who supposedly signed off on the notice. He went to check on the doctor at his office and found the real Dr. Noon chloroformed in his closet. Von Bock and his men then walked in on the hero and Nazi spy used his cunning to beat the Angel. They tied him and Dr Noon up and went to steal the Hall Rapidfire Gun invented by Mr James Hall.
The Angel broke free and stopped Fritz von Bock before he could torture the secret out of Hall. With Von Bock defeated, he was unmasked and turned over to the authorities.[1]
His subsequent fate is unknown.
