““Something had curdled in the atmosphere of the great hall. A further restlessness, a sense of unease, seemed to seep into the air through the walls. The cat, once more in its favored perch in the window recess, began to back up against the shutter, its ears flat and its eyes wide. After a moment even this refuge would not suffice, and it dropped with a small bang onto the table below, leaped to the floor, and scuttled along the wall till it disappeared through an archway near the dais.””
