What happens
Alex Gregory, a chemistry instructor, learns from a Latin note in Professor Jarman's diary that the professor has found a substance called elixir number four, said to grant perpetual life. Gregory is drawn into the professor's laboratory and begins to plan how to obtain the elixir for himself. Starring Richard Whitmark as Alex Gregory, this Inner Sanctum Mysteries episode was first broadcast on February 12, 1946, from an original play by Emil Tepelman. Gregory's ambitions and his dealings with Jarman's daughter, Elaine, drive the early part of the story.

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.
