In 1948, a dead man was found on a beach in Australia. In his pockets were several bus and train tickets, a comb, gum and a piece of paper that said “Tamám Shud.” Oddly enough, his clothing had no labels, he carried no id and his dental records didn’t match any living person.

When looking for a cause of death, authorities found that his spleen was insanely large, his kidneys and liver were congested and there was excess blood in his liver. But there was no sign of poison or trauma. No one knew how he died.

The piece of paper was tracked to a specific copy of a specific book, called The Rubaiyat of Omar Khayyam, and in it, they found a number of a woman who claimed she didn’t know who the man was.
