Then Morrel saw that he had been right in believing that the house was not illuminated. Instead of lights at every window, as is customary on days of ceremony, he saw only a gray mass, which was veiled also by a cloud, which at that moment obscured the moon’s feeble light. A light moved rapidly from time to time past three windows of the second floor. These three windows were in Madame de Saint-Méran’s room. Another remained motionless behind some red curtains which were in Madame de Villefort’s bedroom. Morrel guessed all this. So many times, in order to follow Valentine in thought at every hour in the day, had he made her describe the whole house, that without having seen it he knew it all.
