There was hay here once. Horses, coachmen. Carriages were stored one room over. But that was a long time ago, before this house in lower Manhattan was even on the market, before the construction workers arrived, before the limestone tile for an adjoining hallway was cut, before the hayloft was removed to make room for a spiral staircase and more bookshelves. Before it became the two-story personal library of an unassuming internet mogul. Before Craig.
