He had no other answer."

"If she hadn't asked him a hatani solution he might have helped her."

"Indeed he might."

"She was a fool, Duun-hatani."

"She was also very young and angry. And she hated her father. None of those things helped her."

"Couldn't he warn her?"

"She was old enough to have walked across a province. What point to warn her? But perhaps he did. Anger makes great fools."

"This is the velocity of the system through the galactic arm."

"Is it absolute?" Thorn asked. He had learned to ask; and Elanhen looked pleased. "No," Elanhen said. "But consider it so for this problem…."

They were back to physics. At least two of every five-day set.

There was history. "…In 645 Elhoen calculated the world was round. This was his proof…."

"…in 1439 the hatani took down the shothoen guild and set up the merchant league in its place—"

"…in 1492 the Mathog railway joined the Bigon line and cities grew along the route—"

"…in 1503 Aghoit made the first powered flight. By 1530 Tabisit-tanun flew across the Mathog…. He crashed in the attempt at a polar crossing.

His son and his daughter inherited his interest in the guild and the daughter was lost in a second attempt when ice on the wings forced her landing in Gltonig Bay. That was the last radio message. The plane was 106

found abandoned and no one knew what became of her. The son made the flight successfully in 1541."

"…Dsonan became capital…"

"…The Dsonan League took the Mathog. Bigon resisted. The hatani refused to involve themselves without an appeal from Bigon and there was bloodshed until both sides appealed for settlement. It was the first use of aircraft—"

"…Rocket-bombs were first developed—"

A great unease stirred in him. He turned and looked for help… not Cloen's. About the room the others were at their desks. He held the keyboard on his lap and put in Betan's name.

" W-h-a-t?" the reply appeared white-lettered at the bottom of the screen.

Thorn hesitated. Typed. " W-h-a-t y-e-a-r a-r-e w-e i-n?" His face burned.

He waited for an answer with his heart pounding. Nothing touched the screen. He looked up and saw Betan leave her desk and walk across the sand to him with a puzzled look on her face.

"I don't need your help," Thorn said. "It's just a question."

Betan looked at the screen and looked at him. Her ears flicked down and up and her fine mouth pursed. Standing this close, she smelled of warmth, of flowers, and he wanted Sheon back, he wanted the world as simple as it had been, and the smells of earth and dust and the answers he used to know. "It's 1759," she said. And gulfs opened up about him. Doubtless Betan thought him a fool. Of course they had all grown up in the world and he had had only Sheon. She laughed at him. "Why?"

"It never came up, that's all." He sent the screen on another scroll. It stopped at 1600. Ended. "I need a new cassette."

Betan sat down on the edge of his desk, rested her hand above his knee.

The touch burned him. He looked desperately elsewhere, searching with 107

the tail of his vison for where the others were, but they were all on their desks.

"I'm sorry," Betan said. "I shouldn't have laughed." And she smelled of difference and warmth and his heart pounded against his ribs. She pressed against his ribs. She pressed on his knee and strained his leg and he wished he could get her hand off before something else happened.

"Sheon's not quite the world capital, is it? Look, if you need help with that I'd be happy to stay."

"Duun wants me to be in the gym by noon."

"Ah." She gave his leg a pat and got up. "But it's 1759. The 19th of Ptosin.

It's summer out."

He was suddenly, overwhelmingly conscious of the blankness of the school's white walls. The falsity of the windows behind which (sometimes) was the noise of machinery. The world closed in on him like the clenching of a fist about his heart.

In Sheon the leaves would be green and the hiyi pods opening; the foen-cubs would come tottering out and hiss at the—

—curious country-folk children. Mon was the name of one. They owned his house now. They lived in its rooms. Sat by the fireplace on the warm sand, all together.

Mon. Mon. Mon. He hated that person.

The city closed about him. Imprisoned him. But it was his fault. All his fault. His difference caused it.

"Haras?"

"I can't."

Betan gave up and wandered off, went back to her desk and sat down cross-legged with her back to him. Thorn picked up the keyboard again and looked at the screen.

A message came to him, "BETAN: well, tomorrow, then. I could answer questions, things that bother you,"

He watched it scroll by three times. His heart beat faster and faster. "B-e-t-a-n,"he typed, addressing the response. " Y-e-s."

Thorn picked himself up and dusted the sand off. He bowed. "Yes. I see."

"Again," Duun said. It was not always that Duun stripped down to the small-kilt for practice. Duun did that today, so that his scars were evident, like lightnings through the gray and black hair of his body and his maimed arm, of one fabric with the scars on his face, so that they acquired a fearsome symmetry which Thorn had sensed in those years before he knew that they were scars, or knew that every man in all the world was not marked as Duun was marked, or had not but half a right hand, or did not smile after that permanent fashion, which Thorn knew now was enough to daunt any opponent Duun ever faced. It daunted him now. (He means to put me to it today. He has something in mind.) And it came leaping into his mind in one fatal rush that it had been a very long time that Duun had left him in peace. (Not to interrupt my studies— surely that was why. Or I've gotten better and he won't try—)

That thought vanished in one missed attempt, in the far too lengthy offbalance moment he had to fall as Duun took his feet from under him.

Duun often grinned at such moments. This time he stood there with a dour face, signed no attack and watched with hands on hips as Thorn recovered himself from his drop-and-rise.

"Again."

"Duun-hatani, show me that move to the side again."

109

Cuckoo's Egg

Patiently Duun showed him. Thorn bent himself to it and tried a trick in the midst of it, a joke.

Duun's hands closed on him and dumped him to the ground. (He saw it.) Duun might have laughed, but Duun's face never changed. Thorn hesitated on the safety of the floor a moment, looking up at him. (Gods. He's got something in mind. Something's wrong.) Thorn shook the dazzle and the thoughts and the day from his head and brought himself to his feet again, centered in the tightest possible focus, no thought to anything, no thought, no heartbeat but the beat of the dance, the light and the dust. It was not the city, it was Sheon's noon, and the yard about them, and Duun faced him in purest simplicity.

Pass and evade, strike and recover and pass and turn.

"Better." Duun said, and that one word ran down his nerves like fingers on the dkin. "Better. Take the offensive."

No hesitation. Thorn struck and caught and Duun spun off across the sand, up again in a move that never stopped.

Counter again and attack.

Again.
