(Book 2 Chapters 7-13) What are the stone faces on the chateau? What new “stone face” has been added to the chateau? How did this happen?

The stone face was that of the Marquis, who was killed in his bed.

The Gorgon had surveyed the building again in the night, and had added the one stone face wanting; the stone face for which it had waited through about two hundred years.

It lay back on the pillow of Monsieur the Marquis. It was like a fine mask, suddenly startled, made angry, and petrified. Driven home into the heart of the stone figure attached to it, was a knife.
