After the meal the cosmonauts were allowed out, separately, to relieve themselves, heavily watched all the time.

Kolya took the chance to look around. The plain stretched around him, huge and empty, an elemental sheet of yellow dust broken by splashes of green. Under an ashen sky fat clouds sailed, casting shadows like lakes. But the land, vast and flat and featureless, seemed to dwarf the sky itself. This was the Mongolian plateau—he knew that much from their navigation during the descent. Nowhere much less than a thousand meters above sea level, it was shut off from the rest of Asia by great natural barriers: mountain ranges to the west, the Gobi desert to the south, the Siberian forests to the north. From orbit, he remembered, it had been a vast blank, a faintly crumpled plain stitched here and there with the threads of rivers—barely there at all, like the preliminary sketch of a landscape. And now here he was, stuck in the middle of it all.

And in this vast emptiness the village huddled. The yurts, mud-colored, weather-beaten and rounded, looked more like eroded boulders than anything made by humans. The battered Soyuz descent compartment did not, somehow, look particularly out of place here. But children ran and laughed, and neighbors called from one yurt to the next. Kolya could see animals, sheep, goats and horses, moving in unfenced herds, their lows and bleating carrying in the still air. Though he might be as much as eight centuries out of time, and though there could hardly have been a greater contrast in his origins with these people’s—spaceman and nomad, the most technologically advanced humans put together with some of the most primitive—the basic grammar of human discourse was unchanged, he saw, and he had come to a little island of human warmth, in the midst of the huge silent emptiness of the plain. Somehow that was reassuring, even if he was a Russian fallen into the hands of Mongols.

That night, Kolya and Sable huddled together under a foul-smelling blanket of what smelled like horsehair. The snores of the Mongols were all around them. But whenever Kolya looked up one of them always seemed to be awake, his eyes gleaming in the dim firelight. Kolya didn’t believe he slept at all. Sable, on the other hand, just rested her head against Kolya’s shoulder and slept for hours at a time; he was astonished at her courage.

In the night the wind rose up, and the yurt creaked and rocked, like a boat adrift on the sea of the steppe. Kolya, relentlessly awake, wondered what had become of Casey.

19. The Delta

His breakfast over, Secretary Eumenes dismissed his pages. He pulled his purple cloak over his shoulders, and, pushing the heavy leather door flap out of his way, walked out of his tent.

The clouds had cleared away, revealing a washed-out blue sky, pale like faded paint, and the morning sun was hot. At least the rain had stopped for once. But when he looked west, to the sea, Eumenes could see more black clouds bubbling and boiling, and he knew that another storm was on its way. Even the natives who clustered around the army camp selling charms, and gewgaws, and the bodies of their children, claimed never to have known such weather.

Eumenes set off toward Hephaistion’s tent. It was difficult going. The ground had been turned to soft, yellow mud, churned up by the feet of men and animals, that clung to Eumenes’ cavalry boots.

Around him the smoke of a thousand fires rose to the pale sky. The men were emerging from their tents, hefting clothing and gear heavy with mud. Some of them shaved off their stubble: an order to be clean-shaven had been one of the King’s earliest initiatives when he had taken over the army from his assassinated father, ostensibly so that enemies would not be given an easy handhold in close quarters. The Macedonians moaned, as usual, about this fancy Greek practice, and about the wretched, barbarous state of this place the King had brought them to.

Soldiers always liked to grumble. But when the fleet had first arrived here in the delta, having sailed down the Indus from the King’s camp, Eumenes himself had been appalled by the heat, the stink, the clouds of insects that had hovered over the marshy ground. But Eumenes prided himself on his disciplined mind; a wise man got on with his business whatever the weather. It even rains on god-kings, he thought.

Hephaistion’s tent was a grand affair, far grander than Eumenes’, a sign of the favor with which the King regarded his closest companion. The living quarters were surrounded by a series of vestibules and antechambers, and were guarded by a detachment of Shield Bearers, the army’s elite infantry—reputed to be the finest foot soldiers in the world.

As Eumenes neared the tent he was challenged. The guard was a Macedonian, of course. He certainly knew Eumenes, yet he stood before the Secretary now, holding up his stabbing sword. Eumenes held his ground, his gaze unflinching, and eventually the soldier backed down.

The hostility of a Macedonian warrior for a Greek administrator was as inevitable as the weather—even if it was founded on ignorance, for how did these half-barbarians imagine that the great machinery of the army kept them all alive and provisioned, organized and directed, if not for the meticulous work of Eumenes’ Secretariat? Eumenes pushed his way into the tent without glancing back.

The vestibule was a mess. Chamberlains and pages righted tables, gathered up fragments of smashed crockery and bits of ripped clothing, and mopped up wine and what looked like blood-stained vomit. Last night Hephaistion had evidently once more been entertaining his commanders and other “guests.”

Hephaistion’s usher was a small, fat, fussy man with peculiar strawberry-blond hair. When he had kept Eumenes waiting in the vestibule for just the precise time required to reinforce his own position, he bowed and waved Eumenes forward into Hephaistion’s private chambers.

Hephaistion was on his couch, loosely covered by a sheet, and still in his nightshirt. He was the center of industry: chamberlains laid out clothes and brought in food, and a file of pages brought in jugs of water. Hephaistion himself, propped up on one elbow, picked languidly at a tray of meat.

There was a stirring under the sheet. A boy, eyes heavy with sleep, emerged and sat up, looking bewildered. Hephaistion smiled at him. He touched his fingers to his own lips, and then the boy’s, and patted his shoulder. “Go now.” The boy clambered off the couch, naked. A chamberlain pulled a cloak around him and led him from the chamber.

Eumenes, waiting by the entrance, tried not to show his disdain for all this. He had lived and worked with these Macedonians long enough to understand them. Under their Kings they had been welded into a force capable of conquering the world, but they were highland tribesmen only a couple of generations removed from their ancestral traditions. Eumenes would even strive to join in with their revels when it was politic to do so. But still, some of these pages were the sons of Macedonian nobility, sent to serve the King’s officers in order to complete their education. Eumenes could only imagine what impression it must make on such young men when they spent their mornings mopping up the stinking detritus of some barbarian-warrior in his cups—or spent their nights serving his needs in other ways.

At length Hephaistion acknowledged Eumenes. “You’re early today, Secretary.”

“I don’t think so—not unless the sun has begun to jump around the sky again.”

“Then I must be late. Hah!” He waved a meat-laden skewer at Eumenes. “Try some of this. You’d never think a dead camel could taste so good.”

“The reason the Indians spice their food so heavily,” Eumenes said, “is because they eat rotten meat. I’ll stick to fruit and mutton.”

“You really are a bore, Eumenes,” Hephaistion said tensely.
