The mist was thickening as darkness fell. Being only a five minute walk to the village, there was no reason to feel afraid. She picked up her shopping basket and left the house. Having walked only a few steps, the mist swallowed her up. So, feeling her way along a fence, a twig lashed her face. Then she heard heavy foot steps moving behind her. She stopped and they stopped. Hurrying forward, they pursued. She found herself in a suffocating world seized with a feeling of helplessness and blindness.
