His agonized cry only acted as a spur, and her long legs carried her down the straight, narrow path as fast as she could drive them.

As she ran she kept the fingers of her left hand against the wall of mirrors. It was only by feel that she found a turning, down which she sped. She took another turning, this time to the right, and she ran frantically down yet another nightmare path, her dark hair streaming behind her, her face white, her breath coming in laboured gasps.

She had no idea how long she ran, how often she twisted and turned. It was like running on a treadmill; every step she took brought her to the same place, or what appeared to be the same place.

Finally she could run no more, and she leaned against the mirrored wall, her hands pressing her breasts, her eyes closed as she struggled to regain her breath.

After a few moments she opened her eyes and stared at her reflection in the mirror opposite her. She was shocked to see how frightened she looked, how big her eyes were and how wild and disordered her usually sleek, neat hair had become.

She had no idea where she was. She might still be only a few yards from Pete or she might be in the centre of the maze.

She wondered if she should shout for help, but suppose Pete was close by and got to her before outside help could reach her? She decided it would be safer to try and get out by herself. She looked up and down the path that seemed in the reflection of the mirrors to have no ending and no beginning, and she felt a wave of panic sweep over her.

It was as if she were caught up in some ghastly nightmare. She wanted to sit on the ground and cry: to give up weakly, to hide her face in her hands and wait until someone found her. But suppose Pete found her first? She fought back her tears and made an effort to pull herself together. If she continued down this path, she told herself, and at every intersection she turned left, surely it would bring her to the exit?

She started off, walking slowly, her ears strained to catch the slightest suspicious sound that might come to her above the roar of the amusement park. She hadn’t gone more than a few yards when she had an irresistible urge to look behind her.

She stopped and turned.
