Starvecrow Farm by Stanley J. Weyman

Henrietta sat and listened to the various sounds which told of a household on its way to bed; and she held her courage with both hands. Slip-shod feet moved along the passages, sleepy voices bade good-night, distant doors closed sharply. And still, when she thought all had retired, the clatter of pot or pan in the far-off offices proclaimed a belated worker. And she had to wait and listen and count the pulsations of her heart.

The two wax candles, snuff them as she might, cast but a dull and melancholy light. The clock ticked in the silence of the room with appalling clearness. Her own movements, when she crept to the door to listen, scared her by their stealthiness. It seemed to her that the least of the sounds she made must proclaim her vigil. One moment she trembled lest the late burning of her light arouse suspicion; the next lest the cloak which she had brought in and cast across a chair should have put some one on the alert. Or she tormented herself with the fancy that the snow with which the evening sky had been heavy would fall before she started and betray her footsteps.
