" I had walked over to the window and was looking down at the rails of the Montmartre funicular, the gardens of the Sacré Cœur and, further off, the whole of Paris, with its lights, its roofs, its shadows. Denise Coudreuse and I had met one day in this maze of roads and boulevards. Paths that cross, among those of thousands and thousands of people all over Paris, like countless little balls on a gigantic, electric billiard table, which occasionally bump into each other. And nothing remained of this, not even the luminous trail a firefly leaves behind it. "

― Patrick Modiano
