nothing, he attends his fiancée's birthday party. There, he retrieves an old photo lab receipt from her, which he had given her in pre-Village days. He implies his true identity to her and she seems to almost understand, as Sir Charles, her father, had not seemed willing to do. With the retrieved slides back at his flat – they had previously been developed by Sir Charles' minions, and then returned to the shop – he uses an alphanumeric code system based on Seltzman's name to select certain slides which, projected together and viewed with a special filter, reveal the location of Seltzman. This turns out to be (the fictitious) Kandersfeld, Austria, to which Number Six promptly travels. Seltzman is believed – at least by Number Two and his superiors – to have perfected the reversal of the mind swap process. This is exactly what Number Two wanted, and, Number Six having been followed, both men are gassed into unconsciousness and returned to The Village. The restoration of the identities, however, takes a final unexpected twist: Seltzman agrees to oversee the switchback, but actually does a three-party switch: the body of Number Six gets his mind back, the mind of the Colonel is transferred into the body of Seltzman, who then dies, and Seltzman transfers his own mind into the body of the Colonel, and then leaves on the helicopter before Number Two knows what is happening.
