An impromptu goodbye party for Professor John Oldman becomes a mysterious interrogation after the retiring scholar reveals to his colleagues he has a longer and stranger past than they can imagine.
A character similar to John Oldman--a seemingly immortal Mesopotamian named Akharin (going by the name "Flint" in the episode)--appears in Star Trek: The Original Series: Requiem for Methuselah (1969). This episode is also written by Jerome Bixby.
