years ago. He was following a beautiful mermaid as she swam along the reef and the sight stirred him. I have acted like a schoolboy, he thought, and a bore. Or worse. And why? Because she is pretty? No. Because she is so alive. So much more alive than I am
Carol and Nick made two different excursions, each time starting from the anchor rope, without finding the whales or anything else unusual. When they returned to the anchor after the second unsuccessful foray, Nick pointed at his watch. They had been under the water for almost half an hour already. Carol wagged her head up and down and then held up her index finger, indicating that she would try one more direction.
They found the whales right after they crossed over a big upward bulge in the reef that came within fifteen feet of the surface. Nick saw them first and pointed down. The three whales were about twenty feet below them and maybe thirty yards ahead. They were still swimming slowly, more or less together, in the same directionless, near circular pattern that Nick and Carol had watched on the screen. Carol waved Nick out of the way and pointed at her camera. She then swam toward the whales, taking pictures as she approached them while carefully monitoring her depth and equalizing the pressure in her ears.
Nick swam down beside her. He was certain the whales had seen the two of them, but for some reason they had made no attempt to flee. In all his years as a diver, Nick had only once seen a whale in the open ocean accept the nearby presence of a human. And that had been a calfing mother, in a Pacific Ocean lagoon off of Baja California, whose birth pangs were a more powerful force than her instinctive fear of humans. Here even when Carol approached to within twenty feet or so the whales continued their indolent drift. They appeared to be lost, or maybe even drugged.
Carol slowed her approach when the whales made no attempt to get away. She took some more photographs. Close-up pictures of whales in their natural habitat were still uncommon, so her trip had already been a journalistic success. But she too was puzzled by their behavior. Why were they ignoring her presence? And what were they doing hanging around this particular spot? She remembered being surprised by the solitary whale during her morning swim and wondered again if somehow all these strange events were related.
Nick was off to her right, about twenty yards away. He was pointing at something on the other side of the whales and gesturing for Carol to come toward him. She swam away from the great mammals and headed in Nick's direction. She saw immediately what had attracted his attention. Below the whales, just above the ocean floor, there was a large dark hole in the bottom of an imposing reef structure. At first glance it appeared to be the entrance to an underground cave of some kind. But Carol's sharp eyes noticed that the lip-shaped fissure was extremely smooth and symmetric, almost suggesting to her that it was an engineering construction of some kind. She laughed at herself as she swam up beside Nick. The amazing underwater world and the bizarre behavior of these whales were playing tricks with her mind.
Nick pointed down at the hole and then at himself, indicating that he was going down to check it out more closely. When he started to leave, Carol had a sudden impulse to reach for his foot and pull him back. A moment later, as she watched Nick swim away, a powerful fear of unknown origin swept over her. She began to tremble as she struggled gamely with this strange emotion. Goose bumps appeared on her arms and legs and Carol felt an overwhelming desire to get away, to escape before something terrible happened.
An instant later she saw one of the whales move toward Nick. If Carol had been on land she could have yelled, but fifty feet deep in the ocean there was no way to warn someone from afar. As Nick drew near the opening, unaware of any danger, he was brushed to the side by one of the whales with such force that he bounced against the reef and then caromed off. He fell down onto a small spot of sand on the ocean floor. Carol swam toward him quickly while keeping a careful eye on the whales. Nick
