When the man appeared in front of her, she could not imagine, at first, where he had come from. It was as if he had appeared by magic from the sand.

“Max,” she cried. “Max. How did you get here? I didn’t see you.” And she began to run towards him, tears streaming down her face.

It was only when she saw the blade of the wide, triangular kitchen knife, shining in the moonlight, that she began to feel afraid. It was that and his failure to answer, his stillness and silence. She realised then that he had been waiting for her crouched behind one of the blocks of concrete. He had known all the time where she was. He had seen her on the high dune, watched her walk along the tide line, and waited patiently for her return. She screamed and began to run away from him. She knew instinctively that she would have no chance against him on the flat sand. He was stronger than she and much faster. Her only hope was to get back to the car.

She began to scramble up the dunes on all fours, pulling with her hands and kicking with her feet. He seemed surprised by her sudden movement and could not use both hands because he was still holding the knife, blade outstretched. But he seemed to have power in his legs to compensate, and when she slipped, gulping for air, exhausted, he almost caught her. She kicked back with one foot, sending a shower of fine sand over his face and into his eyes. He swore and lunged forward with the knife towards her, but he could not see and missed her. She ran on. She could not hear him behind her. She slowed down for a moment and listened, but there was no sound of movement. He must have followed a different path, she thought. He would hope to trick her by getting ahead of her and cutting her off from the car. She stood quite still and listened again, but there was silence.
