I have found an interesting story: http://en.wikipedia.org/wiki/Taman_Shud_Case
A man was found dead (from an unknown cause) on a beach in Adelaide,
A thorough search of his body eventually led to a piece of torn out paper being found in a hidden trouser pocket. The piece of paper contained the words ‘Taman Shud. ’ ‘Taman Shud’ loosely translates to ‘the end.’ These words are the closing words of a book of poetry by Omar Khayyam called The Rubaiyat. A local professional found this very book on the back seat of his car with the words ‘Taman Shud’ torn out the night before the mystery man was found dead. Laboratory results confirmed that this very book matched up to the piece of paper located on the deceased man.
On the back page of the book, a mysterious code was printed:
Maybe someone will be able to decrypt/decode it
