About midnight Christian's doze deepened into a sound sleep, and Lucia too, sitting in the warmth of the store, slept in spite of herself.

For nearly an hour the room was so still that Mrs.Costello could count every tick of her watch, and every change in the flickering sound of the wood fire.

_She_ had no inclination to sleep.

It was still a mystery to her how this could be, but the feeling had its own exquisite sweetness, how dearly soever that sweetness was bought; and she drank it in greedily.
