In this paper I propose an interpretation of Calvino's Cosmicomiche in the framework of possible-worlds fiction theory. I use this theoretical framework to make an ‘interpretative bet’ on the name of the main character and narrator of these stories: can we read Qfwfq as a stylistic constant which refers to Kafka as an interpretative function? In my reading, Kafka is not a descriptive content of the name ‘Qfwfq’, but a semantic model relative to Qfwfq's possible worlds. The definition of this model provides a unified interpretation of the cosmicomic project and contributes to a new reading of Calvino's late works
