Archimedes is famous for being Ancient Greece's greatest engineer. Yet a random discovery - a prayers book found in an old church in Turkish Istanbul, casts this mysterious genius in an even more surprising light. 

We're back from our short break, with a fantastically interesting episode:
In 1989, a message was found in a virus: "Eddie Lives…Somewhere in Time!". 'Eddie' was a particularly nasty virus, and its discovery led a young Bulgarian security researcher down a rabbit hole, on a hunt for the prolific creator of the Eddie virus: The Dark Avenger.
