At long last, she thought, they had come to a place where this simple pleasure, a walk in the open air, did not mean exposure to imminent peril. High walls of stark, weather-beaten stone protected the cove from behind and to either side, reaching long tendrils out into the water. And between its arms and hollow chest a strip of sand, perhaps a mile long and a third as deep, lay open to the sea and sun. Lack of game, as much as the forbidding walls, kept the predatory threat of the land animals away from them. So Kalus had told her.

For this same reason he had never considered the margins of the sea as a home of any duration. But on that night when he felt its call so strongly, remaining upon the high watch until the fiery sun had risen from its depths to light the land, Sylviana had spoken of the many ways that food could be obtained there. His restless thought needed no other prompting. In the following weeks they had taken what they needed and could carry, and come the gray stone distance to the north and east, to live. That Kalus had another reason for doing so he kept to himself, a seeming contradiction to the intimate closeness of those days. But he knew the symptoms of his heart and would not cross them. Not yet. He was afraid, and at the same time drawn, to the thing he did not understand.

The girl watched happily as Alaska made a reckless charge back through the surf, crashing the shallow water against her chest with the inexhaustible energy of youth. Having lived more than half her life among humans, it seemed a perfectly natural thing to do: running in joyful frolic toward the outstretched, clapping hands of her soft, female friend. And as she came to a sudden, impulsive halt, shaking the cold water from her fur, she took little notice as Sylviana turned a puzzled gaze far out across the waters. It only meant that her friend no longer wished to play.

Sylviana couldn't believe her eyes. IT HAS TO BE AN ILLUSION, she thought. SOME KIND OF MIRAGE. But still the image lingered. Perhaps a half mile out, a lone human figure had just emerged from the water and propped itself gracefully atop a tiny islet, a mere rock at the edge of the continental shelf, which had somehow survived the weathering of the years.

At least it looked human. Just at the distance where eyesight begins to fail and imagination to fill the void, the creature looked strangely surreal: something from an ancient legend of the sea. Half blocked from her vision by the stone, only its naked back and blondish mane were visible. These seemed human enough. But she was sure she remembered something odd about the way it emerged. . .the way it moved. . something.

But suddenly her eyes descried a far more substantial form, undeniable. A huge, black dorsal fin split the surface of the water like a knife, then began to move in slow patient circles around the speck of land and shelter. Incredibly, the lone figure seemed not to notice.

Like wildfire, the thoughts and fears chased each other through her mind. MY GOD, ANOTHER HUMAN! PERHAPS THE LAST. AND A SHARK! I'VE GOT TO DO SOMETHING! Cupping her hands in front of her mouth, she inhaled as deeply as her anxiety and thumping heart would allow, and shouted in desperation:

'Look out! Stay out of the water, there's a shark!' It was no use, the north wind and crashing surf devoured her feeble warning. Trying to master her panic, she took several deep breaths, and cried out at the top of her lungs.

'Shark! Shark! Stay out of the water. A SHARK!'

This time the creature reacted. Turning towards the sound, it returned her startled gaze with one of its own, revealing for an instant a young, almost childish face. Then to her horror, it leapt into the water immediately beside the giant killer. Frozen in terror she could only watch, unable to move or think. She didn't breathe.
