On December 1, 1948, police found a well-dressed stranger propped against a seawall on Somerton Beach, Adelaide — every label cut from his clothes, no wallet, no name. What followed became one of Australia's most examined unsolved cases: a scrap of paper hidden in his trousers reading Tamám Shud, "it is finished," and five lines of code that have defeated cryptographers for over seventy-five years.
This book traces the case from the sand of Somerton Beach through the coronial inquest, an abandoned suitcase at Adelaide Railway Station, a nurse whose phone number turned up beside the cipher, and the Cold War suspicions that drew in Australian intelligence near the Woomera rocket range. It follows the science through 2021, when investigators exhumed a grave that had carried no name for seventy-three years, and 2022, when DNA finally gave the man an identity: Carl Webb, an ordinary Melbourne tradesman with no clear reason to die the way he did.
Every claim here comes from coronial records, contemporaneous newspaper accounts, and official findings — never guesswork.
