So, steering away from the scary virus stuff, I went down another interesting path with the clue. Now, I don't think this is the right answer for OBVIOUS reasons, but it's a really interesting "rabbit hole" nonetheless (going the OWCA route). Sometimes these deep dives end up in interesting places:
* Clue is of Perry the Platypus
* Perry lives a double life as "Agent P" (which is his character in this clue)
* "Agent P" is a spy who works for the OWCA (Organization Without A Cool Acronym)
* In 2006, a movie named "Black Sheep" was released worldwide. But in Poland, it was released under the title of "Czarna Owca" (owca is the Polish word for sheep)
* Czarna Owca was released in Poland on July 19, 2008
* Also released on July 19, 2008 was a horror film named The Midnight Meat Train
* The Midnight Meat Train was based on a Clive Barker book of the same name
* Clive Barker = Hellraiser
Again, I don't think this is the answer. And I wasn't attempting to get to this answer, as much as I would love the property. But, that's where the OWCA avenue took me organically, and thought you guys might find it intriguing.
