A story of the author's childhood in New York City. "Resisting the deadening silence of his family home in the elegant yet stiflingly safe neighborhood of Gramercy Park, nine-year-old Roger imagines himself a private eye in pursuit of criminals. With the dreamlike mystery of the city before him, he sets off alone, out into the streets of Manhattan, thrilling to a life of unsolved cases. Six decades later, Rosenblatt finds himself again patrolling the territory of his youth: The writing class he teaches has just wrapped up, releasing him into the winter night and the very neighborhood in which he grew up. A grown man now, he investigates his own life and the life of the city as he walks, exploring the New York of the 1950s; the lives of the writers who walked these streets before him, such as Poe and Melville; the great detectives of fiction and the essence of detective work; and the monuments of his childhood, such as the New York Public Library, once the site of an immense reservoir that nourished the city with water before it nourished it with books, and the Empire State Building..."--Description from publisher.
