HIDDEN DANGER... John laughed as he swam, pleased that he had tricked Peter. The water felt good, even though it was muddy. His mom might be mad about him swimming in his clothes and shoes, but it was worth it. He was splashing along, Cinnamon paddling at his side, when he felt something gently tugging at his legs. It felt like an undercurrent, but that didn't make sense. The water wasn't moving. It was just a big, quiet lake in an empty field. John kicked hard, trying to swim forward. Instead, to his surprise, he was pulled sideways--fast! Suddenly, the current was much stronger. Instead of sweeping him sideways, it was now sucking him down! "Help!" he sputtered. "Help!" He was still yelling when the muddy water closed over his head.
