Dracula by Bram Stoker Chapter 12 Page 23

Quincey Morris said nothing about his intention, but I knew that all night long he patrolled round and round the house.

When the day came, its searching light showed the ravages in poor Lucy's strength. She was hardly able to turn her head, and the little nourishment which she could take seemed to do her no good. At times she slept, and both Van Helsing and I noticed the difference in her, between sleeping and waking. Whilst asleep she looked stronger, although more haggard, and her breathing was softer. Her open mouth showed the pale gums drawn back from the teeth, which looked positively longer and sharper than usual. When she woke the softness of her eyes evidently changed the expression, for she looked her own self, although a dying one. In the afternoon she asked for Arthur, and we telegraphed for him. Quincey went off to meet him at the station.
