December 1, 1948. A well-dressed man is found dead on Somerton Beach, Australia. No ID. No wallet. Every tag cut from his clothes.
Hidden in a secret pocket sewn into his trousers, police find a torn scrap of paper reading "Tamam Shud" β Persian for "it is ended." It leads investigators to a rare copy of a 12th-century book of poetry... with five mysterious lines of code scrawled inside the back cover.
For 73 years, cryptographers, the FBI, and amateur codebreakers around the world try to crack it. Nobody succeeds.
Then in 2022, science finally answers half the mystery. Using DNA extracted from a single hair trapped in the man's decades-old death mask, researchers identify him: Carl "Charles" Webb, an electrical engineer from Melbourne with a broken marriage and a life that had quietly fallen apart.
We finally know who he was.
But the code found beside his body? Still, to this day, unsolved.
We break down the evidence, the science, and the mystery that's outlasted three generations of investigators.
The Somerton Man mystery: a secret code, a 73-year identity mystery finally solved by DNA β and the cipher nobody has ever cracked. Full true crime breakdown.
