“All summer,” he said. He carried a fishing spear that he used as a staff.

So that was it! A summer holiday. “Where are your families?”

“Oh, they’re inland. It is too dangerous for them on the beaches.”

“Dangerous?” That didn’t sound like vacation!

“The blacks,” he said, as though that explained it.

“What are the blacks?”

He looked uncomfortable. “They come up from the sea. I thought you knew all about — that. We have to stop them from infesting the land. Every year some try. If they ever take hold and start breeding—” He looked ahead. “There it is! I wanted you to see it.”

She followed his gaze and spied an abutment of rock — a sheer cliff rising out of the sea, twenty feet high. It was an unusual formation, since the vertical side faced away from the ocean and toward the beach. Harold would have made some observation about reverse tidal undercutting, but she didn’t really understand that kind of thing. It was very pretty.

The clouds had overcast the sun, but as if stage-directed they parted to let a beam come down. It struck the sea-side of the rock, and there was a brilliant flash from the edge.

“What is that?” she asked, concerned.

“The sun-stone,” he said, ru

The overcast closed in again, but as she came up to the cliff she discovered why the rock had seemed to take fire. It was mirror-surfaced! The face toward the beach was a clean fracture that had been polished by nature or man until it shone. The beach was reflected in it, and the distant trees, making it appear almost like a window to another world.

Could she step through? Would that convey her back to—

Then she saw herself within it, and gasped.

She had lost twenty years. Her hair was thick and blonde, as it had been before she settled in to married life. Her face was thin, narrow-chi

“And you said you were not fair!” Hume said, divining her thoughts. “You said you were forty.”

“But I was — am,” she said, confused. “I don’t understand this.”

“Why try? Too much understanding only brings sorrow, as we well know.” And he was off again down the beach, the mirror-rock a fancy only of the moment.

She lingered, ostensibly to investigate the other facets of the structure, all as clear as the first but much smaller, but actually taking in the marvelous picture. The too-scant suit — now it was voluptuous. She was young again, and… fair. Perhaps she had known it before, and not believed.

“Tryx!”

She jumped, surprised by his impatience, and ashamed to be caught indulging in schoolgirl vanity, and ran to him. Yes, she could recognize it now: she had the vitality of a girl of seventeen.

But Hume’s exclamation had not been impatient. He had found something.

A line of footprints crossed the beach from the water to the trees. They were not human; the indentations were too large and shallow, even where the moist sand near the surf held them well. Webbed prints.

“It must have crossed within the hour,” Hume said tersely.

A reaction ran up her bare back and tightened the nape of her neck. “A — black?”

He nodded. “We can’t catch it now. Impossible to run it down in the brush, except with a full party.”

“What can we do?” The tension made her feel nauseated in exactly the way Ivo had described.

“I’ll stand guard here. You run back to the village and warn the others. And be careful — they usually travel in pairs and cross in different places, so that if we get one — hurry!”

Fear gave her fleetness. She skipped over the sand, ru

She passed the mirror-stone and went on, panting already. How far had they come down the beach? At least a mile — a long, long distance, now. What if the black came back before she fetched the others? Hume had only his spear. Those awful footprints…

She had to slow down. She was young, but she could not keep up this headlong pace. Her side ached.

She walked, recovering. She felt guilty, as though she were malingering, but this was the best she could do. She glanced over her shoulder, half afraid something would be coming after her, and saw that the mirror-stone was already out of sight. That made her more nervous than ever.

Something caught her eye in the water, and she turned back. She jumped, though she knew it was only a wave, or perhaps a bit of driftwood coming into sight between the swells. She started to run again, but the pain in her side came back quickly, dragging at her strength.

Again that shape in the ocean, attracting her unwilling eye. She forced herself to look carefully, trying to convince herself all the way down inside that it was nothing. Only a freak swell caused by adjoining currents in the tide; that was what Harold would say, comfortingly.

A black, monstrous-eyed head rose out of the whitening froth, two glossy ante

Beatryx screamed.

It was the wrong thing to do. Instantly the head swiveled to cover her. She saw its banded snout, the fixed round hole of a toothless mouth beneath. It was earless, but it had heard her — and now it was swimming or slithering toward her with alarming speed.

She bolted for the forest, but the loose dry sand caught at her feet while giving way beneath them, impeding her and throwing her off balance. She fell, sand flying up and into her face. She choked on it and tried to brush it out of her eyes, but her hands were covered with it.

Somehow she could not get coordinated. She remained on hands and knees in the sand, watching the creature through streaming eyes.

The thing rose out of the water and came at her, a towering ebony figure. The scales of its thick body gleamed metallically. She saw through her sandy tears that its extremities — all four of them — were webbed. This was a black!

Then it loomed above her, hoisted upon two legs, the great square bulk of its forward segment swaying near. The ante

A cry in the distance! The black’s head rotated toward the sound and its dangling flipper-forefeet hoisted up. The others had heard her cries! They were coming! The brute shuffled around and away, driving for the ocean. But already a party of men were ru

“Joy! You are all right!” Persis cried, ru

“Hume!” Beatryx gasped, remembering. “He — he’s watching for another one! Beyond the mirror-stone!”

“The sun-stone!” Several men detached themselves and pounded on down the beach, holding their spears aloft. They understood.

Meanwhile six men were closing in on the nearby creature. It spun about awkwardly, seeking some passage to the water, but there was none. At last it charged, a caged bull, raising its solid forelimbs threateningly.

Durwin’s spear thunked into its body. The black stumbled, clutching at the shaft but not mortally wounded, and the men were on it.

“Kill it! Kill it!” Persis screamed, her eyes dilated, her fingers curved into claws.

“Kill it!” Beatryx echoed, horrified by the narrowness of her escape.

The spears rose and fell in a frenzy of attack. The sea-thing’s gross body twisted and fell, bright red blood dripping down its scales. A kind of groan issued from it; then it collapsed face-down in the sand, the water lapping at the tip of one forelimb.

“It’s dead,” Durwin said with grim satisfaction. “Now let’s go after that other one. Spread out and watch for any more along the beach, too.”
