The protagonist is discovered by Murray, who reveals himself to be an undercover operative from military intelligence also investigating Dalby. The protagonist escapes, but is soon captured by Jay's operatives and taken to meet Jay—he has, however, allowed military intelligence to follow them, and Jay and Dalby are arrested by Colonel Ross. The protagonist reveals to Jean that Jay and Dalby were using a process called "Induction of Psycho-neuroses by Conditioned REflex with Stress" (IPCRESS) to brainwash the VIPs into loyalty to the Soviet Union, which they had also unsuccessfully attempted to subject the protagonist to. The seemingly irrelevant links that Carswell had discovered were in fact indicators of the personality traits that Jay had used to determine which VIPs would easily succumb to the process. Dalby was the one who had spied on the American bomb test, as part of Jay and Dalby's efforts to frame the protagonist. Colonel Ross reveals that his attempt to sell information to the protagonist had been a test of his loyalty, which the protagonist had passed by rejecting it. The novel ends with the protagonist concluding his report to the Minister, revealing that Jay has turned and began working for the British, while Dalby has ostensibly died in a car accident.
