On the other side of the world, Smiley looked down at a sheet of paper in his hands. The sheet contained the names of the six agents he concluded were likely working with HYDRA. Three names were crossed off, three agents passing Smiley's barium meal test. Now it was time for number four.

"Sisyphus..." Smiley didn't have the man's name on his list. It violated protocol, but time was of the essence. "Agent Jackson is to be searched as soon as you return to the mainland. If he is discovered smuggling documents from Tiger Shark's yacht, he is to be arrested immediately and held in the local safehouse until I can arrive in Jakarta. If you understand, simply sign off and proceed with the part of the mission as instructed."
