The Story of the World's Oldest Prisoner

January 18, 2026·51 min·4 clips

A dispute over smoking with an American in a cafe triggered Wallace's paranoia—and ended with a fatal shooting.

Bill had almost disappeared into routine. Gideon Hay pictures him among long benches, soup, meat and sweet, and the hush of an older Australia. Almost, but not quite. On December 9, 1925, two young men enter and knock him out of that fragile quiet. One of them, Gene McRobertson, has a loud American accent, the kind that lands hard in a country not yet used to talkies or many Americans. Bill notices.

Outside, a group gathers, and the fight reaches the point where a butcher only sees the final, terrible part. The butcher asks what Bill has done. Bill keeps giving the same answer: he had to do it. The episode lets that answer sit there, then works through age, memory, paranoia, and what it can do to a person to outlive the world they understood. It also treats the material carefully, naming support lines for listeners affected by abuse or distress and leaving space for anyone who needs help after hearing it.
