As we burst into the room, the Count turned his face, and the hellish look that I had heard described seemed to leap into it. His eyes flamed red with devilish passion; the great nostrils of the white aquiline nose opened wide and quivered at the edge; and the white sharp teeth, behind the full lips of the blood-dripping mouth, champed together like those of a wild beast.
– Bram Stoker
Dracula, Chapter 21. When Dr. Seward, Van Helsing and the others rush to the Harker home to save Mina from Dracula, they discover they are too late. Like a scene straight out of hell, Seward describes the wild beast appearance of the Count after he had satiated himself on the blood of Mina.
