I was intrigued by the story of the Somerton Man, found dead on the beach in Australia in 1948. He remains unknown, his life and death a mystery. What is know is that he had a piece of paper with the words "Tamam Shud" in his pocket. Taken from the Rubaiyat of Omar Khayyam, a translation of 11th century Persian poems by Edward Fitzgerald. The words mean "It is finished".
