Unsolved Codes

An interesting list.  Here's my favorite:

...An unidentified male body was found on Somerton Beach in Adelaide, Australia in 1948 wearing a sweater and coat despite the hot day, carrying no identification. There were no clues as to his identity and dental records and fingerprints matched no living person. An autopsy discovered bizarre congestion, blood in the stomach and enlarged organs but no foreign substances. A suitcase found at the train station that may have belonged to the man contained a pair of trousers with a secret hidden pocket, which held a piece of paper torn from a book imprinted with the words “Taman Shud”. The paper was matched to a very rare copy of Omar Khayyam’s ‘The Rubaiyat’ that was found in the backseat of an unlocked vehicle and on the back of the book was scrawled five lines of capital letters that seem to be a code. To this day, the entire case remains one of Australia’s most bizarre mysteries...
