Dracula

From the text:

Lucy was breathing somewhat stertorously, and her face was at its worst, for the open mouth showed the pale gums. Her teeth, in the dim, uncertain light, seemed longer and sharper than they had been in the morning. In particular, by some trick of the light, the canine teeth looked longer and sharper than the rest.

There did not seem to be with her now the unconscious struggle for life and strength that had hitherto so marked her illness. It struck me as curious that the moment she became conscious she pressed the garlic flowers close to her. It was certainly odd that whenever she got into that lethargic state, with the stertorous breathing, she put the flowers from her; but that when she waked she clutched them close.
