The morning came in gray, as all mornings did, the fog pressed against the windows of the town like a damp cloth. In the square, the guards were already at their posts, their breath forming small clouds that vanished almost immediately. Levi, the oldest of them, stood by the fountain with his ledger, and it was there that he saw Boaz, the miller's son, crouched at the edge of the fog line with a length of string in his hands.

Levi walked over, his boots heavy on the wet stones. "Boaz," he said, and the name hung in the air like a question. Boaz looked up, his eyes wide, the string still wrapped around his fingers. "You know the rule," Levi said. Boaz nodded but did not move. Levi waited, then reached down and took the string from him, rolling it into a neat coil. "That's a fine," he said. "For measuring." Boaz opened his mouth to speak, then closed it. He stood, brushed the damp from his trousers, and walked back toward the mill. Levi watched him go, then wrote the fine in his ledger, the ink blotting slightly on the damp page.

Across the square, Liora and Meir were arguing over a crate of apples that had tipped over near the grocer's stall. Meir said it was Liora's fault, that she had backed into it. Liora said it was his, that he had left it in the middle of the path. The argument escalated quickly, as arguments in the square often did, and before anyone could step in, Liora had shoved Meir, and Meir's hand had caught her shoulder, and they were tumbling into the spilled apples, their voices rising above the murmur of the market. Two guards pulled them apart, and the crowd that had gathered dispersed, shaking their heads. Liora's daughter Rachel stayed behind, helping her mother pick up the apples, and when Meir had gone, Rachel sat with Liora on the edge of the fountain, talking in low voices that no one else could hear.

In the infirmary, Dr. Elam (the elder, not the younger, though they shared the name) made his rounds. Shira the carpenter lay in the third bed, her face pale with the valley fever, her hands trembling slightly on the blanket. The doctor noted she had lost three days to it, and that she was mending. Two beds down, Ira the younger, the cafe owner, slept fitfully, the same fever coloring his cheeks. Gilead the younger, the carpenter, was in the next room, and Elam the younger—the teacher, who had also taken ill—was in the last bed, his face turned to the wall. The doctor recorded each case in his small book: valley fever, three days, recovering.

At the far end of the infirmary, a woman lay in a bed that had been prepared the night before, a newborn wrapped in a cloth beside her. The child was Hosea the younger, born just after midnight, and the woman, exhausted, had fallen into a deep sleep. The doctor had heard the child murmur something in its sleep, a string of words that had made him pause, but he did not write it down.

In the west corridor of the town hall, Liesl Kfir stood at the window, looking out at the fog. She had been turned back at the fog line that morning, a guard with a polite but firm voice reminding her that the Council preferred people to stay at their work. She had work, she had plenty of it—a broken pump at the mill, a cracked gear in the generator—but she could not keep her mind on it. She kept thinking of the second splash, the one only she had heard, the one that came a fraction of a second after the first, from somewhere deep in the well. Noa Hadar had asked her about it again that morning, pressing her ear to the cobblestones, and Liesl had told her the truth: she did not know where it came from. "But it's real," she had said, and Noa had nodded, her eyes scanning the ground as if she could see the sound with her hands.

Fernando the instrument maker spent the morning in his workshop, calibrating his chronometer. He had timed the fog's drift yesterday and found nothing unusual, but he had written it down anyway, as he did with all things. In the afternoon, he walked to the well, set his chronometer on the edge, and lowered a small weight on a string. He waited, listening. The well was silent. He pulled the weight up, checked his dials, and wrote: No second sound. He sat there for a long while, the silence of the well pressing against him, and then he packed up his tools and walked home.

At the south road, a guard turned Garrin back at the fog line, the same words repeated like a ritual: "The Council prefers people to stay at their work." Garrin, the Clerk of the Record, had intended only to check the measurement markers, but he had not even reached them. He nodded, turned, and walked back toward the hall, his boots leaving prints in the damp dust.

The births came in the afternoon. Hosea the younger, the first, was born at the hall, and Joel, the second, just an hour later. Both children, the midwife noted, were healthy, their cries strong. But it was what happened after they slept that unsettled her. Each child, in its sleep, murmured a sentence in a voice that sounded like their own, though they were too young to speak: "the fog is just fog." The midwife told the mothers, who told their husbands, and by evening, the story had spread through the town, carried on breaths and whispers. Dalia Shalev, the town reporter, heard it from three different people, and she wrote it down in her notebook, though she did not know what to make of it. Zipporah Gefen, the old miller, heard it in the market and said it was a coincidence, a trick of the air, nothing more. But she stayed up late that night, staring at the fog outside her window.

Miriam Segal, the baby who had spoken the same words in her sleep, lay in her cradle at the edge of the room. Her mother, Elam's wife, had told no one about the whispers today, but she had heard them, faint and clear, and she had pressed her hand to her chest to steady her heart. Miriam slept through the evening, her lips moving once, small and silent, and the fog outside the window leaned closer, as if it were listening.

The day ended as it had begun: gray, quiet, watchful. Liesl closed her shop and stood in the dark, listening for the second sound. Noa Hadar walked the perimeter of the square, her ear to the ground at intervals, finding nothing. Fernando sat at his desk, writing his notes. And in the hall, the two new babies slept, their mouths slightly open, as if they were holding their breath for what was to come.
