you is a theory.” He switched into reporting mode. “It looks like the world—the other world, I should say—is shutting down. From what I can gather, there was some sort of virus over there, and it knocked out most of the population. Maybe all of the population, I don’t know. And when they go, so do we. That seems to be the way it works. Mind you, all of this is just a theory. It doesn’t explain what the two of us are still doing here.”
“I came here across a desert,” the blind man said.
And that evening, as he sat lightly on the cushions of Luka’s sofa, like a paper kite poised to catch the wind, he was still recounting the story. He had finished off the last of the red wine and fettuccine Luka had prepared, and he was tearing tiny pieces of his napkin off and collecting them in his palm. “I thought it was only the whistling of the wind at first. It took me a while to hear the pulse.” The blind man repeated the exact same detail for what must have been the sixth or seventh time, and Luka made another little affirmatory noise. He was unwilling to let the blind man go, unwilling to leave him alone for even the few seconds it would take to rinse the dishes or put the leftovers away, for fear that he would disappear. “All that sand, and it wouldn’t stop moving,” the blind man said, and when he brought his hands together, the confetti pieces of his napkin drifted to the floor.
They stayed up talking until long after the sun had set. Then Luka offered the blind man a place on his couch to sleep, and because it was late and the blind man was still tipsy from the wine, he accepted.
Luka lay awake half the night listening to him breathe.
The next morning he was still there, sitting on the sofa, running his hands over a wing-shaped piece of driftwood that Luka had fished out of the river. He had folded the blanket Luka had given him into a perfect square, positioning it in the center of his pillow. When he heard Luka come into the room, he said, “I think there must be more of us.”
“More of us?”
“More of us left in the city.”
“Why do you say that?”
The blind man was quiet for a long time. “Instinct.”
And though Luka couldn’t say why, he was inclined to agree. Since he had noticed the tapping noise outside his window, he had been quick to investigate any unusual sound: a nut falling from an oak tree, his refrigerator hatching another clutch of ice cubes. He would let the sounds sail around in his short-term memory until he was satisfied that he could identify them. Then he would get up and head to the window or the kitchen just to make sure. It was as though every sound that was not the wind or the birds or the river was by definition human. He imagined people all over the city, hundreds of them, trying everything they could think of to pierce through the walls of their solitude, but uncertain there was anybody out there. Hundreds of faces behind hundreds of windows. Hundreds of coats gliding around hundreds of corners. He was determined that he wouldn’t stop looking until he had picked out every last one of them.
He and the blind man spent the day searching for anyone they could find. Luka tried to offer him his elbow as they started out, but the blind man refused it. “A man who’s walked as far as I have doesn’t need anybody’s help,” he said. Instead, he navigated by trailing his hand along the wall of whichever building they were passing, listening to the echo of his hard-soled shoes as they hit the sidewalk.
The two of them began at Luka’s apartment building, venturing outward in a series of linked rings. “We should stay in one place,” the blind man argued. “Other people are going to be out searching, too.” And he had a point—someone could easily happen by the apartment building while they were away—but Luka was too restless to stay put. He preferred to take his chances in the city.
They walked down street after street, the blind man shouting out,
