In 1948, an unknown man was found dead on Somerton Beach in Adelaide, Australia, dressed neatly in a suit with no identification and all clothing labels removed. Investigators discovered a tiny rolled-up paper in his pocket with the words “Tamám Shud”, meaning “ended” or “finished” in Persian, torn from a rare copy of The Rubáiyát of Omar Khayyám. The matching book was later found in a car, containing a strange code and a phone number of a local nurse named Jessica Thomson, who seemed nervous when questioned. For decades, his identity and cause of death remained unsolved, leading to wild theories — from espionage to a secret love affair. In 2022, advanced DNA testing finally identified the man as Carl “Charles” Webb, an electrical engineer from Melbourne who had gone missing in 1947. Yet, even with his name known, how he died, why he carried the mysterious note, and what the hidden code meant still remain unanswered, keeping the Tamám Shud case one of the world’s greatest unsolved mysteries.
