The grey colors of evening were beginning to spread across the ocean and the sand. He hurried on, then suddenly, he stepped into the water. Before he knew what had happened, he dropped down and down. The water was covering his head. He rose to the top of the water struggling to get back on to the dry sand. He felt the water rushing about him. Somehow, he got on to the sand and sat down wet and surprised at his sudden drop. He heard the water still rushing about. Then, he saw a long grey shark. He stood up and looked around. He saw the shark swim toward the shore. And then, he saw other sharks, five, six, seven of them, but where was the sand reef? What had happened to it? He began to walk back toward the island. While he had searched for shells on the island, the strong ocean waves had washed a large part of the sand reef away. There was nothing between him and the shore, but water and sharks.
