Good-night." It was half-past eleven by the clock in the passage as they went upstairs to the bedroom, the window of which looked on to the wood at the back of the house.
Isaac locked the door, set his candle on the chest of drawers, and wearily got ready for bed.
The bleak autumn wind was still blowing, and the solemn, monotonous, surging moan of it in the wood was dreary and awful to hear through the night-silence.

Isaac felt strangely wakeful.
He resolved, as he lay down in bed, to keep the candle alight until he began to grow sleepy, for there was something unendurably depressing in the bare idea of lying awake in the darkness, listening to the dismal, ceaseless moaning of the wind in the wood.
Sleep stole on him before he was aware of it.

His eyes closed, and he fell off insensibly to rest without having so much as thought of extinguishing the candle.
The first sensation of which he was conscious after sinking into slumber was a strange shivering that ran through him suddenly from head to foot, and a dreadful sinking pain at the heart, such as he had never felt before.

The shivering only disturbed his slumbers; the pain woke him instantly.

In one moment he passed from a state of sleep to a state of wakefulness--his eyes wide open--his mental perceptions cleared on a sudden, as if by a miracle.
The candle had burned down nearly to the last morsel of tallow, but the top of the unsnuffed wick had just fallen off, and the light in the little room was, for the moment, fair and full.
Between the foot of his bed and the closed door there stood a woman with a knife in her hand, looking at him.
He was stricken speechless with terror, but he did not lose the preternatural clearness of his faculties, and he never took his eyes off the woman.
