The Owner of the Voice and the botanist are soon required to account for their presence. When their thumbprints are checked against records in "the central index housed in a vast series of buildings at or near Paris," both discover they have doubles in Utopia. They journey to London to meet them, and the Owner of the Voice's double is a member of the Samurai, a voluntary order of nobility that rules Utopia. "These samurai form the real body of the State." Running through the novel as a foil to the main narrative is the botanist's obsession with an unhappy love affair back on Earth. The Owner of the Voice is annoyed at this undignified and unworthy insertion of earthly affairs in Utopia, but when the botanist meets the double of his beloved in Utopia the violence of his reaction bursts the imaginative bubble that has sustained the narrative and the two men find themselves back in early-twentieth-century London.
