She again glanced rapidly from Pierre's face to that of the lady in the black dress and said:,...!, Almost every time a new carriage drove up a whisper ran through the crowd and caps were doffed., In the damp chill air and crowded closeness of the swaying carriage, she for the first time vividly imagined what was in store for her there at the ball, in those brightly lighted rooms- with music, flowers, dances, the Emperor, and all the brilliant young people of Petersburg.
