I started writing
in the weeks after moving from the Upper West Side of Manhattan to the suburbs of Boston. More than anything, I missed walking in the city, down Broadway, up Columbus, where there was always the chance of something interesting happening.
In the suburbs, I felt a kind of sensory deprivation. I still walked, to the library a few blocks away, to the town center that was half a mile from my house, but there was little to look at, no one I might pass: just houses, just cars.
On every visit I made back to New York, I felt my eyes regaining a wider stance. I was like a tourist, always looking up. Once I started writing about the city, my homesickness eased. When I wrote, I could still be on my beloved streets, still walking as I always had.
But as home as I felt, there was no denying the fact that the city I was writing about was changing – new buildings were going up, stores were changing, the people I knew moving away. The city I was writing about was my particular version of a place that comes in millions of versions. Each city dweller occupies a different place. We all navigate our own internal maps. In addition to the sights we see around us, there are parts of the city that exist in our memories: those old buildings that once stood, torn down to make way for something new. The people who occupied our apartments before us, leaving behind tiny traces.
And there are also parts of the city buried out of sight. As I wrote
, I became fascinated with the idea of yet another version of the city that lay below, the old “ghost” subway stations which are no longer in use but still intact. The stacks beneath the New York Public Library, what used to be the water system of the Croton Aqueduct. The labyrinths beneath Grand Central. The steam pipes and atomic tunnels beneath Columbia University. The unused Amtrak tunnels under Riverside Park.
As a novelist, the metaphors were inescapable: what parts of ourselves are buried too? Can those closed-off parts ever come above ground, become visible?
