On soft sand by the sea's edge a little boy walked leaving no footprints. Gulls cried in the bright sunless sky, trout leaped from the saltless ocean. Ear off on the horizon the sea serpent raised himself a moment in seven enormous arches and then, bellowing, sank. The child whistled but the sea serpent, busy hunting whales, did not surface again. The child walked on casting no shadow, leaving no tracks on the sand between the cliffs and the sea. Ahead of him rose a grassy headland on which stood a four-legged hut. As he climbed a path up the cliff the hut skipped about and rubbed its front legs together like a lawyer or a fly; but the hands of the clock inside, which said ten minutes of ten, never moved.

«What's that you've got there, Dicky?» asked his mother as she added parsley and a pinch of pepper to the rabbit stew simmering in an alembic.

«A box, Mummy.»

«Where did you find it?»

Mummy's familiar leaped down from the onion-festooned rafters and, draping itself like a foxfur round her neck, said, «By the sea.»

Dicky nodded. «That's right. The sea washed it up.»

«And what's inside it?»

The familiar said nothing, but purred. The witch turned round to look into her son's round face. «What's in it?» she repeated.

«Darkness.»

«Oh? Let's see.»

As she bent down to look, the familiar, still purring, shut its eyes. Holding the box against his chest, the little boy very carefully lifted the lid a scant inch.

«So it is,» said his mother. «Now put it away, don't let it get knocked about. I wonder where the key got to. Run wash your hands now. Table, lay!» And while the child worked the heavy pump handle in the yard and splashed his face and hands, the hut resounded with the clatter of plates and forks materializing.

After the meal, while his mother was having her morning nap, Dicky took down the water-bleached, sand-encrusted box from his treasure shelf and set out with it across the dunes, away from the sea. Close at his heels the black familiar followed him, trotting patiently over the sand through the coarse grass, the only shadow he had.

At the summit of the pass Prince Rikard turned in the saddle to look back over the plumes and pennants of his army, over the long falling road, to the towered walls of his father's city. Under the sunless sky it shimmered there on the plain, fragile and shadowless as a pearl. Seeing it so he knew it could never be taken, and his heart sang with pride. He gave his captains the signal for quick march and set spurs to his horse. It reared and broke into a gallop, while his gryphon swooped and screamed overhead. She teased the white horse, diving straight down at it clashing her beak, swerving aside just in time; the horse, bridleless, would snap furiously at her snaky tail or rear to strike out with silver hoofs. The gryphon would cackle and roar, circle back over the dunes, and with a screech and swoop play the trick all over. Afraid she might wear herself out before the battle, Rikard finally leashed her, after which she flew along steadily, purring and chirping, by his side.

The sea lay before him; somewhere beneath the cliffs the enemy force his brother led was hidden. The road wound down growing sandier, the sea appearing to right or left always nearer. Abruptly the road fell away; the white horse leaped the ten-foot drop and galloped out over the beach. As he came out from between the dunes Rikard saw a long line of men strung out on the sand, and behind them three black-prowed ships. His own men were scrambling down the drop, swarming over the dunes, blue flags snapping in the sea wind, voices faint against the sound of the sea. Without warning or parley the two forces met, sword to sword and man to man. With a great shrilling scream the gryphon soared up, jerking the leash from Rikard's hand, then dropped like a falcon, beak and claws extended, down on a tall man in gray, the enemy leader. But the tall man's sword was drawn. As the iron beak snapped on his shoulder, trying to get the throat, the iron sword jabbed out and up, slashing the gryphon's belly. She doubled up in air and fell, knocking the man down with the sweep of her great wing, screaming, blackening the sand with blood. The tall man staggered up and slashed off her head and wings, turning half blinded with sand and blood only when Rikard was almost on him. Without a word he turned, lifting his steaming sword to parry Rikard's blow. He tried to strike at the horse's legs, but got no chance, for the beast would back and rear and run at him, Rikard's sword slashing down from above. The tall man's arms began to grow heavy, his breath came in gasps. Rikard gave no quarter. Once more the tall man raised his sword, lunged, and took the whizzing slash of his brother's sword straight across his uplifted face. He fell without a word. Brown sand fell over his body in a little shower from the white stallion's hoofs as Rikard spurred back to the thick of the fight.

The attackers fought on doggedly, always fewer of them, and those few being pushed back step by step toward the sea. When only a knot of twenty or so remained they broke, sprinting desperately for the ships, pushing them off chest-deep in the breakers, clambering aboard. Rikard shouted to his men. They came to him across the sand, picking their way among hacked corpses. The badly wounded tried to crawl to him on hands and knees. All that could walk gathered in ranks in a hollow behind the dune on which Rikard stood. Behind him, out on deep water, the three black ships lay motionless, balanced on their oars.

Rikard sat down, alone on the dune top among the rank grass. He bowed his head and put his hands over his face. Near him the white horse stood still as a horse of stone. Below him his men stood silent. Behind him on the beach the tall man, his face obliterated in blood, lay near the body of the gryphon, and the other dead lay staring at the sky where no sun shone.

A little gust of wind blew by. Rikard raised his face, which though young was very grim. He signaled his captains, swung up into the saddle, and set off round the dunes and back toward the city at a trot, not waiting to see the black ships steer in to shore where their soldiers could board them, or his own army fill up its ranks and come marching behind him. When the gryphon swooped screaming overhead he raised his arm, grinning at the great creature as she tried to perch on his gloved wrist, flapping her wings and screeching like a tomcat. «You no-good gryphon,» he said, «you hen, go home to your chicken coop!» Insulted, the monster yawped and sailed off eastward toward the city. Behind him his army wound upward through the hills, leaving no track. Behind them the brown sand lay smooth as silk, stainless. The black ships, sails set, already stood out well to sea. In the prow of the first stood a tall, grim-faced man in gray.

Taking an easier road homeward, Rikard passed not far from the four-legged hut on the headland. The witch stood in the doorway, hailing him. He galloped over, and, drawing rein right at the gate of the little yard, he looked at the young witch. She was bright and dark as coals, her black hair whipped in the sea wind. She looked at him, white-armored on a white horse.

«Prince,» she said, «you'll go to battle once too often.»

He laughed. «What should I do—let my brother lay siege to the city?»

«Yes, let him. No man can take the city.»

«I know. But my father the king exiled him, he must not set foot even on our shore. I'm my father's soldier, I fight as he commands.»

The witch looked out to sea, then back at the young man. Her dark face sharpened, nose and chin peaking cronelike, eyes flashing. «Serve and be served,» she said, «rule and be ruled. Your brother chose neither to serve nor rule … Listen, prince, take care.» Her face warmed again to beauty. «The sea brings presents this morning, the wind blows, the crystals break. Take care.»
