The man on Somerton Beach

A well-dressed stranger, no wallet, every clothing label cut away. A torn scrap of Persian poetry sewn into a hidden pocket. A pencilled code no one has broken in seventy-eight years. Season One reopens Australia’s most famous cold case.

Persian: “it is ended”  ·  6 episodes

On the morning of 1 December 1948, a man was found slumped against the seawall at Somerton Park, south-west of Adelaide. He carried no identification. Months later, investigators found a tiny rolled paper in a concealed fob pocket bearing two words torn from The Rubaiyat of Omar Khayyam. The copy it came from turned up with a phone number and five lines of pencilled capitals in the back. In 2022 researchers named him through DNA from his death mask. They still can’t say why he died, or what the code means.
