I recently came across this story. It's about an unsolved death back in 1948 in Australia. The Persian connection? Well, here's a paragraph from the Wikipedia piece:

The Taman Shud Case,^{[note 1]} also known as the Mystery of the Somerton Man, is an unsolved case of an unidentified man found dead at 6:30 a.m., 1 December 1948, on Somerton beach, Glenelg, just south of Adelaide, South Australia. It is named after a phrase, tamam shud, meaning "ended" or "finished" in Persian, printed on a scrap of paper found in a hidden pocket of the man's trousers. This turned out to have been removed from the final page of a particular copy of The Rubaiyat of Omar Khayyam. Following a police appeal, the actual book was handed in – around the time the body was found, a man in Glenelg had found it on the seat of his car. Written in the book was something looking like a secret code as well as a telephone number.

It's a fascinating mystery with a Persian oetry twist. Here's the Wikipedia link:
