Close to the Edge (Unabridged ed)

The hunter has become the hunted. Laurie Bateman has been drifting through life, stuck in a dead-end job in London, while she still calls Somerset home.

Then, in morning rush hour on the London tube, she witnesses a terrible accident.

Memories of her mother's death ten years before come flooding back. Compelled to investigate, Laurie breaks into the underground at dead of night to look for clues.

The ambush comes out of nowhere, forcing her to flee for her life through pitch black tunnels and deserted stations.
