An exultant novel of New York City at the turn of the twentieth century, about one man's rise to fame and fortune, and his mysterious murder--"engrossing" (Wall Street Journal), "immersive" (The New Yorker), and "seriously entertaining" (The Sunday Times, London). Andrew Haswell Green is dead, shot at the venerable age of eighty-three, when he thought life could hold no more surprises. The killing--on Park Avenue in broad daylight, on Friday the thirteenth--shook the city. Born to a struggling farmer, Green was a self-made man without whom there would be no Central Park, no Metropolitan Museum of Art, no Museum of Natural History, no New York Public Library. But Green had a secret, a life locked within him that now, in the hour of his death, may finally break free. A work of tremendous depth and piercing emotion, The Great Mistake is the story of a city transformed, a murder that made a private man infamous, and a portrait of a singular individual who found the world closed off to him--yet enlarged it.
