The hall was quiet now, but the quiet had a weight to it, like the air before a storm. Liesl stood among the cots, her hands loose at her sides, her eyes moving from one sleeping child to the next. Dalia had not moved from the doorway, her notebook still pressed against her chest, her pen in her other hand, unmoving.

Outside, the square was empty, the lamps lit against the fog that pressed in from every edge of town. The night was ordinary, or as ordinary as any night had been since the fog first arrived. No one spoke of the voices, not yet, but the news would spread by morning, the way news always spread, through kitchens and workshops and the low murmur of the mill.

Liesl stepped away from the cots and walked to the door. Dalia lowered her notebook and looked at her, but neither of them said anything. They stood together in the doorway, looking out at the square, where the fog hung like a wall beyond the last houses. Somewhere, a dog barked, and then fell silent.

In the morning, the town went about its work as if nothing had happened. The blacksmith opened her shop, the baker lit his ovens, the guards paced their rounds along the fog line. But everyone moved a little slower, listened a little harder. The children in the hall had been counted, checked, and found healthy. Their parents took them home, cradling them close, but no one could say why they held their children a moment longer than usual.

Liesl Kfir went to the cafe table on the plaza, as she had planned, and sat down with her stopwatch. Hillel Barak came across the square and took a seat across from her. He set a notebook on the table, its pages worn, and opened it to a page marked with a ribbon. "Shira said it again last night," he said, his voice low. "Same words, same tone. I timed it with my watch—eleven seconds, start to finish."

Liesl nodded. "I heard the children in the hall. Five of them, one after another, same sentence. I didn't time it. I should have, but I couldn't move."

Hillel looked down at his notebook. "You said you'd test your hearing with a metronome. Did you?"

"Not yet," Liesl said. "I came here first." She glanced across the square toward the old well, visible at the end of a narrow street. "I wanted to ask around first, see if any other parents have children repeating phrases."

"I did, this morning," Hillel said. "Two mothers said their kids mutter in their sleep, but nothing clear. No exact phrases."

"Same as my asking," Liesl said. "Nothing." She picked up her stopwatch, clicked it once, and set it down. "But the well—Dalia and I both heard the splash late. And the children all spoke the same sentence. Those aren't natural. Those are—" She stopped, not finishing.

"Patterns," Hillel said quietly.

Liesl looked at him, and for a moment her face was open, uncertain. "I don't trust my own senses anymore," she said. "That's the worst of it."

Elsewhere, at the north survey post, Zipporah Gefen stood with Eli Segal. A guard had turned her back the day before, but this morning he waved her through, and she walked the four blocks she'd counted before, her tape measure in her hand. Eli held the other end against the post, and together they ran it out to the wall. "Fifty-four centimeters," Eli read from the tape. "Each block exactly the same."

Zipporah wrote in her notebook, then crouched and laid her palm against the stone. "The survey says six blocks," she said. "I counted seven. You count now."

Eli walked along the wall, his finger touching each block. At the sixth, he stopped, then the seventh. "Seven," he said. "Unless I'm missing a seam." He ran his hand back over the sixth, then the fifth. "They're each the same size. Seven blocks."

Zipporah stood and brushed the dust from her knees. "And my rangefinder gave me 212 going out, 196 coming back. You said your time-lapse showed the fog line moving from 112 to 103."

Eli nodded. "Same camera, same spot. No wind."

Zipporah looked at the fog, which stood silver and still at the end of the field. "I'm going to pace it myself," she said. "From the post to where the fog starts. Count my own steps."

"I'll come with you," Eli said, and together they walked toward the wall, their steps falling in time. The guard watched them from a distance but did not move.

At the old well on the south edge, Garrin Zohar stood with his stopwatch, and a few paces away, Joel Gefen and Gilead Meron looked on. Garrin dropped a stone into the dark water. It struck the surface—a single clear splash, and then, one second later, a second, quieter splash, like an echo from the bottom. Garrin clicked his stopwatch, clicked it again. "One point zero two," he said, and wrote it down.

Joel stepped forward with his own stopwatch. "Let me try," he said, and dropped a stone. Same result. Two splashes, one second apart. Garrin looked at his notebook, then at the well. "The patrol is eight minutes," he said. "Every day, same as the survey. But the splash is late, every time. I don't know what to trust."

Zipporah arrived then, Garrin's name on her lips. She stopped at the edge of the well, breathing a little hard. "Garrin, you said the fog line is forty-one paces from here. I paced the north wall today, counted seven blocks, and my rangefinder read different going out and coming back. The guard let me through today, but I couldn't finish—the fog was too close."

Garrin looked at her, then at the well, then at the fog line. "Forty-one paces," he repeated. "I measured it this morning, same as every day."

"Let me count," Zipporah said. "From the lip of the well to where the fog starts. My own steps."

Garrin nodded, and Zipporah walked, her steps measured, counting aloud. "One, two, three—" She reached the fog and stopped. "Forty-one," she said, turning back. "Same as yours."

"So the wall is seven blocks, the rangefinder is off, and the splash is late," Garrin said. "But the fog line is fixed. I don't know how to make that fit."

Zipporah came back to him. "Tomorrow we'll measure it together," she said. "From here, with our own steps. If we agree, then it's the instruments. If we don't, it's us."

Garrin looked at his stopwatch, then at the blank page in his notebook. "The record has been kept for forty years," he said. "If the wall is wrong, the record is wrong. I need to know which of us is off—me, or the town."

He did not say the fog. Neither did Zipporah. But both looked out at the gray line, which held its place, patient and unmoving, as if it had all the time in the world.

By evening, the town had settled again. The children were asleep in their homes, their parents watching them, listening for any sound. Liesl sat in her shop with a metronome, setting it to one-second intervals, earbuds in her ears, a recorder running. She listened to the clicks, one after another, each on time. She stopped after a minute, pulled out the earbuds, and looked at the recorder. The clicks were even. No lag. She set the metronome down and sat in the quiet, her hands folded on the workbench.

At the mill, Ophir Segal and Naomi Meron had come to blows over a spilled sack of grain, and they parted with red faces and torn sleeves, no one sure what had started it. Yarden Eshel, the surveyor, lay in the hall with a fever, three days lost to the valley's sickness, his maps beside him, untouched.

Tamar Kfir held her newborn son, Oren, and watched his small face in the lamplight. He had not spoken since the first time, but she waited, her thumb against his chest, counting his breaths. The words hung in the air of the room like something not quite heard, a sentence that belonged to the fog and not to any of them, but which they carried anyway, day after day, in their sleep and in their waking.

Night fell, and the fog remained at its posts, silver and still. In the hall, the lamps burned low. The children slept. And in the silence between their breaths, for a moment, the town could almost hear it—the sound of something waiting, patient as the wall, steady as a metronome, ticking one second at a time, as if counting toward a beginning no one had yet imagined.
