“I know you want the canned food,” he said to it. “But you don’t get to decide what you eat. I’m the decider.” He flashed a goofy grin, impressed by his own wit, which the terrier couldn’t or wouldn’t appreciate. But the dog did seem to understand that it wasn’t going to get its wish, and bent its head reluctantly to the bowl of dry kibble. “Good boy,” the man said, and went to see about his own breakfast.

The man had slept poorly, plagued as usual by anxiety dreams in which he searched endlessly for something he had promised to find—though whether the something was a person or an object he could never quite remember. The sense of frustration continued to haunt him even now that he was awake. As he stood by the open refrigerator looking blankly within, he wondered, Where are they? and then, Where is what?

He was still staring into the fridge when he heard the patter of what he assumed was rain against the side of the house. The dog, facing the sliding glass patio doors and able to see what was really going on outside, let out a terrified bark and ran to hide in the pantry.

“You whine all you want,” the man said. “You’re still not getting the canned food.” As the storm intensified he shut the refrigerator door and went into the hall and called upstairs to his wife: “Hey Laur? You awake? You better go shut the windows in the spare room!”

Ninety miles away in Crawford, the man David Koresh called the Quail Hunter was in the CIA’s interrogation wing, extracting a confession from a recalcitrant Quaker. The basement torture room was windowless and soundproof, but even so he sensed the arrival of the storm as a sudden tremor in his heart.

“Sir?” asked a centurion who was holding a bucket of water above the prisoner’s head. “Should I go again?”

The Quail Hunter started to gesture Yes, yes, and something trickled onto the back of his hand. He looked up. A hole had appeared in the ceiling and sand was streaming down through it like the grains in an hourglass. He felt his heart give another kick.

“Sir?” the centurion said. “Sir?”

In Virginia, David Koresh sat at his desk with his Bible open to the Book of Revelation. He thought he understood what was happening and ought to have welcomed it, but now that he was getting what he’d prayed for he found himself in doubt, the rasp of the sand on the window behind him sounding more and more like the crackle of a fire.

Across the Potomac, Colonel Yunus stood in the dinosaur gallery of the Smithsonian, marveling at the sand sifting down through the growing cracks in the skylight. He felt no fear, even as the roof began to give way; in the dust cloud that came boiling towards him, he saw the outline of a house, and faces of a family that he knew. He said: “God willing.”

All around the globe—in Berlin and the occupied territories; in London and Tehran, Kabul and Denver, Chicago and Jakarta, Islamabad and Corpus Christi, Los Angeles and Mumbai; in Alexandria and Alexandria—the storm scoured the landscape, roaring through the homes and hiding places of the powerful and the meek like some mighty voice: Refresh. Refresh. This is the day the world changes . . .

And in Baghdad, a tall man stalking the halls of a mansion found himself suddenly outside, exposed to the storm’s full fury. The wind tore the rifle from his hands and the pelting sand drove him to his knees. Blind, he clawed his way forward, seeking shelter, a cave to crawl into. There was nothing. He quickly became exhausted. Sinking down, he felt sand piling up around him and prepared to be buried alive.

The storm abruptly ceased. The tall man raised his head and saw only darkness. He stood up in the black stillness, listening to his own labored breathing, and felt rather than heard the heavy footsteps coming up behind him. The back of his neck prickled. Hot breath whispered in his ear as someone taller even than he was leaned in over his shoulder.

“Who goes there?” Osama bin Laden said, and then he turned around.

Epilogue

The City of the Future

When Mustafa comes back to himself he’s on top of a big pile of sand, one dune among many, a sea of sand extending to the horizon. He doesn’t know which desert this is. The Sahara is the obvious guess, but it could just as well be the Rub al Khali, or the Nafud, or something completely new.

He is kneeling as if to pray, and indeed it is about that time: When he looks up, the sun is directly overhead. But instead of prostrating himself, he stands, brushing sand from the robe he has somehow come to be wearing. The hem of the robe hikes up and he sees that his feet are clad in leather sandals, a good pair, nicely broken in.

Straightening, he continues to take inventory. Things he has: A robe. Comfortable shoes. The first hint of a beard. Things he does not have: Pockets. A wallet. A watch. A map. Food. Water. That last could be a problem, though he’s not thirsty yet. Supposing that he will be soon enough, he turns around, to see whether perhaps there’s an oasis behind him. There isn’t; just more dunes. He has all the sand he could wish for.

Continuing to turn, he spots something else, sticking up out of the dune a few meters away from him: a boot. He goes over and pulls it up, pours out the sand, and turns it over in his hands. It’s a tall boot, tan leather and nylon with a thick rubber sole. There are no markings on it, inside or out, but it looks military.

Well, Mustafa thinks, now I have a boot. But it’s the wrong size for him—he can see this, even before he measures it against the bottom of his sandals—and its mate is nowhere to be found, so after a few moments he tosses it, and watches it roll and bounce down the dune face.

As the boot comes to rest, he detects more motion in his peripheral vision: Amal and Samir, climbing up opposite sides of the dune. Amal is wearing a blue abaya that shimmers brightly in the sunlight. Samir is dressed in city clothes: socks and loafers, khakis, a cotton shirt that is already stained with sweat.

Mustafa nods hello to them and they nod back, everybody affecting a casual attitude, as if meeting in the middle of nowhere like this were a natural occurrence. As maybe, in this world, it is. They stand side by side at the top of the dune and look out over the high and rolling sands stretching far away.

Samir is the first to speak. “Well,” he says, “here we all are in the desert.” Looking down at his empty hands: “With nothing.”

“We are alive at least,” Amal offers.

“That is one theory,” says Mustafa. But he says it good-naturedly, feeling not so much optimistic as philosophical: If this is the same world he woke up in yesterday, then he hasn’t lost anything he hadn’t already lost. If it is a new world, it is as apt to contain good surprises as bad ones. He supposes he should consider the possibility that they are in hell, but the fact that he can still smile, however faintly, makes that seem unlikely. And in any case, whining will change nothing. “I guess we should start walking.”

“OK,” Samir says. “Which way?”

Three Muslims adrift in the desert could do worse than follow the Qibla direction. Of course Mustafa has no idea which direction that is, but he remembers the direction he was kneeling in, so they strike out that way. At first they try to travel in a straight line, but after trekking up and down a few dune faces in the noonday sun, they decide to zigzag instead, following the troughs between dunes.

They’ve only gone two or three kilometers when they come upon the jeep. It is buried nose-down in the sand, its front hood and most of its windshield covered, its tailgate and right rear wheel sticking up at an angle. Like Mustafa’s boot, it is unmarked but looks military. Its green paint job has been scoured by the sand.
