She wrung her arms in woe; the horror of what she was doing tore her in pieces; but not all this prevented her turning back.

It could not even make her go slowly.

She did not walk back; she stole back in little runs.

She knew it was her destruction, but her arms were outstretched to the spot where she had left him.
He was no longer there, and he saw her between the firs before she could see him.

As he realized what her coming back meant, his frame shook with pity for her.
