This is Part VIII of Conspiracy. It is not so much a horror story as an intrigue thriller. I have studied intelligence and espionage fairly extensively throughout university, writing my senior thesis on intelligence analysis. This tale is essentially an attempt to write up a good spy story in the world of the SCP Foundation.
Special thanks to Dmatix for his help relating to SCP-1440; on a related note, I recommend the tale "Thrice" to help better understand Harper's conversation with SCP-1440.
