Here’s a creepy mystery for you. This is an unsolved case of an unknown dead man.

The body of the man was found dead at 6:30 am on December 1st, 1948, in Adelaide, South Australia. Several factors may have contributed to the popularity of this case, including what appeared to be a secret code on a scrap of paper in the victim’s pocket and the use of an undetectable poison.

Witnesses claim to have seen him (or a man resembling him) lying in the same spot and position earlier the previous evening. All the labels on his clothes were missing, although they did appear to be of high quality. He had no wallet or distinguishing marks, and his face was clean-shaven.

Although many people came forward through the course of the investigation to say they could identify the man, all of the claims were dis-proven.

Not strange enough yet? A tiny, rolled-up piece of paper torn from a book was found sewn into the man’s pocket. The words “Tamam shud” were printed on it, and it was translated to mean “ended” or “finished.” This led a man to tell police that he had found a copy of “The Rubaiyat” in the backseat of his unlocked car (it was the 40s after all), a couple of weeks before the body was found. Tests later confirmed the ripped page was from the same book. The back of the book appeared to have some kind of code written in pencil.

Also in the book was the unlisted phone number of a nurse, who said she owned a copy of “The Rubaiyat,” but had given it away to a man named Alfred Boxall. The woman’s reaction to the plaster cast that was made of the dead man led police to believe that he was in fact Boxall. At least, they did until they found Boxall alive, and still in possession of his copy of “The Rubaiyat.”

Here is one final mystery about this case. Years after the burial, flowers began appearing on the grave. Who was the mystery man? The most plausible theory, given the time, was that the mystery man was a spy. Even if that is the case, it would just go to show that sometimes fact is stranger than fiction.
