Céline occupies cell 609, section K. His immediate concern is legal survival. France wants him returned, and he is determined to avoid extradition.
But the notebooks soon cease to function simply as legal preparation. Lucette brings him books. He reads Chateaubriand, Hugo, Chamfort, Voltaire and others, quoting and responding to them. He thinks about writers who have endured imprisonment or exile and begins placing his own situation within that literary tradition.
His memories also open outward: Montmartre, London, his life with Lucette and the journeys that brought him to Denmark.
Most importantly for the later novels, prison becomes an experimental writing space. Jean-Paul Louis describes the notebooks as documenting the transition toward Céline's "second narrative and stylistic revolution." Material begun here will feed Féerie pour une autre fois and later the German trilogy.
