What happens
Clark Kent, the reporter who is secretly Superman, leaves Colonel Greeley in occupied Germany, convinced that the scientist Dr. Teufel is developing a weapon from kryptonite that could threaten Superman. Meanwhile, Major Carol heads to a village after an American sergeant signals for help. In a hidden cave in the Black Forest, Teufel and Professor Milch prepare a treatment on a young German named Milch's son. The episode ends with the young man apparently dead and Teufel insisting the outcome is impossible. The Adventures of Superman was a radio serial, and this episode was first broadcast on October 18, 1945.
Occupied Germany, including an American base in a village and a secret cave in the Black Forest, with a stop in Metropolis.
Characters: Clark Kent, Superman, Colonel Greeley, Major Carol, Sergeant Nelson, Dr. Teufel, Professor Milch
Listen for: Teufel's insistence that the young man cannot be dead, and whether the kryptonite experiment has failed.
Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
