You can lose yourself or disappear in a big city. You can even change your identity and live a new life. You can indulge in a very long investigation to find a trace of malice, starting only with one or two addresses in an isolated neighbourhood. I have always been fascinated by the short note that sometimes appears on search records: Last known address. Themes of disappearance, identity and the passing of time are closely bound up with the topography of cities. That is why since the 19th century, cities have been the territory of novelists, and some of the greatest of them are linked to a single city: Balzac and Paris, Dickens and London, Dostoyevsky and Saint Petersburg, Tokyo and Nagai Kafū, Stockholm and Hjalmar Söderberg.
