— Arthur C. Clarke ~ It was now fully dark except for the resplendent light show that the Aurora was creating in the sky. Stewart had lost all hope that they were not in danger. There was no way that Mark would have stayed down there that long without communicating with him. Something must have happened to them. Stewart had been sitting there on the flybridge for several hours chewing on the problem. Something had definitely gone wrong. An accident maybe, or possibly Dierdra had found them. After all, it was something down there she didn’t want them to find. However, the second option seemed out of the question. He had been on the lookout almost the entire time, and there had been no other boats. Even when he hadn’t been up top, the proximity alarm would have gone off if any other vessel had approached. Maybe the sharks had eaten them, possible, but unlikely. Mark had informed him that no one had ever been killed by a lemon shark, a few rare attacks.
