Some of the names in his network are those of real people (most of whom he has never met), but some are made up. Wormold tells only his friend and World War I veteran, Dr. Hasselbacher, about his spy work, hiding the truth from Milly. At one point, he decides to make his reports "exciting" by sending to London sketches of what he describes as a secret military installation in the mountains, actually vacuum cleaner parts scaled to a large size. In London, nobody except Hawthorne, the only one to know that Wormold sells vacuum cleaners, doubts this report. However, Hawthorne keeps quiet for fear of losing his job. In the light of the new developments, London sends Wormold a secretary, Beatrice Severn, and a radio assistant codenamed "C" with much spy paraphernalia. On arriving, Beatrice tells Wormold she has orders to take over his contacts. Her first request is to contact the pilot Raúl. Under pressure, Wormold develops an elaborate plan for his fictitious agent "Raúl". However, to his surprise, a real person with the same name is killed in an apparent car accident. From then on, Wormold's manufactured universe overlaps with reality, with threats made to his "contacts". Together, Beatrice, who still believes the contacts to be real, and Wormold try to save the real people who share names with his fictional agents. Meanwhile, London passes on the information that an unspecified enemy, implied to be a Soviet contact, intends to poison Wormold at a trade association luncheon, where he is the speaker. It would seem that his information has worried local operatives who now seek to remove him. London is pleased by this, as that validates his work. Wormold goes to the function and sees Dr. Hasselbacher, who loudly warns him of the threat. Wormold continues to dinner where he manages to refuse the meal that is offered and eats another one. Across the table sits a fellow vacuum cleaner salesman he had met earlier, Carter, who offers him whisky. Suspicious, Wormold knocks over the glass, which is then drunk by the headwaiter's dachshund, which soon dies. In retaliation for the failure, Carter kills Dr. Hasselbacher at the club bar. Captain Segura, a military strongman in love with Milly and intending to marry her, has a list of all of the spies in Havana, which Wormold would like to send to London to partially redeem his employment.
