At dawn on 1 December 1948, the body of a well-dressed man was found leaning against a seawall at Somerton Beach in Adelaide.
He carried no identification. Nobody came forward to claim him, and the labels had been removed from much of his clothing.
It was the beginning of one of Australia’s most enduring mysteries.
The Unknown Man on the Beach
The man appeared to be about 40 years old and was dressed in a suit, polished shoes and knitted jumper. An unused train ticket to Henley Beach and a bus ticket to Glenelg were among his possessions.
There was no obvious injury, struggle or sign of violence.
Witnesses later recalled seeing a man in the same position on the previous evening. Some thought he was drunk or asleep. One witness remembered seeing his arm move before it dropped back to the sand.
The post-mortem examination found congestion in several organs, but no poison was detected by the methods available at the time. Investigators suspected poisoning, although they could not prove it.
The cause of death remained undetermined.
The Suitcase at Adelaide Station
Police later connected the unidentified man with a suitcase left at Adelaide Railway Station on 30 November.
It contained clothing, personal items and tools. Some labels had been removed, while other items carried the names “Keane” or “T. Keane.”
Investigators searched for a missing man by that name but found nobody who could be conclusively connected to the body.
The suitcase provided clues—but no identity.
The Words “Tamám Shud”
Months later, investigators discovered a tiny rolled-up piece of paper concealed in a small pocket inside the man’s trousers.
Printed on it were the Persian words “Tamám Shud,” generally translated as “finished” or “ended.”
The paper had been torn from the final page of a copy of The Rubáiyát of Omar Khayyám.
After the discovery was publicised, a man handed police a copy of the book that had reportedly been thrown into his car around the time of the death. The torn section matched the hidden scrap.
Inside the book were several lines of letters resembling a code and a telephone number belonging to a local woman, Jessica Thomson.
Thomson denied knowing the dead man, although accounts of her reaction led some investigators to suspect otherwise. No convincing solution to the apparent code has ever been established.
Was the Somerton Man a Spy?
The missing labels, unexplained code and death during the early years of the Cold War naturally encouraged theories of espionage.
Adelaide was also connected with the Woomera weapons-testing program, adding fuel to the idea that the unknown man might have been involved in intelligence work.
However, no reliable evidence has proved that he was a spy. His death may have had a much more personal explanation.
A Name at Last?
In 2022, University of Adelaide researcher Professor Derek Abbott and forensic genealogist Colleen Fitzpatrick announced that DNA research pointed to Carl—often called Charles—Webb.
Webb was born in Melbourne in 1905 and worked as an electrical engineer and instrument maker. Records suggest that he had separated from his wife, Dorothy, who later moved to South Australia.
The identification offered possible explanations for several clues, including clothing marked with the Keane name, which may have belonged to Webb’s brother-in-law.
However, the identification had still not been formally confirmed by the South Australian coroner as of October 2026.
One Mystery Replaced by Another
Even if the Somerton Man was Carl Webb, the central questions remain unanswered.
Why did he travel to Adelaide? Was he searching for his estranged wife? What caused his death? Why was the scrap from The Rubáiyát hidden in his clothing, and what did the letters in the book mean?
After more than seven decades, the unknown man may finally have a name.
The full story of his final hours, however, may have gone with him to Somerton Beach.
