 After being relieved of his position as head of the Russia House, Ned is sent to the "Interrogators' Pool," a division not held in high regard within the service.In addition to supplying interrogators to debrief defectors or captured enemy agents, the Pool acts as a clearing-house for suspicious members of the public who believe they have relevant information for the government.While browsing through the Pool's old files, Ned is excited to find an old record from Smiley's tenure there (after being relieved of his position as Chief at the end of "The Honourable Schoolboy").
