In the morning, the fog lay as it always did, a white wall at the town's edges, and the people of Neshiyah went about their work as if the day were ordinary. But it was not ordinary, for at the old well at the south edge, a small crowd gathered before the sun was high. Liesl Kfir stood at the well mouth, her mechanical stopwatch in her hand, and Dalia Shalev stood opposite her, holding a small recorder. Noa Hadar was there too, her phone raised, marking the release and the splash.

Liesl dropped the stone from arm height. It hit the water with a sound that carried up the stone walls, and Dalia said, "Hear it." A second later, Liesl said, "Hear it." Noa played back the recording, and they all heard it: Dalia's voice, then a heartbeat of silence, then Liesl's voice. Dalia marked the timestamps on paper, and the difference was a full second on every drop. "You hear a second splash," Dalia said, not asking. Liesl nodded. "One splash, then a soft echo about a second later. You don't hear it." Dalia shook her head. "Just the one."

Later, Ivo Segal came to the well, his face drawn. He asked Liesl if her fog-side test had explained anything, and she told him it hadn't, that the splash was still late even from inside the fog line, and that she heard a second sound that Dalia did not. Ivo listened, then said, "My boy still says 'the fog is just fog' in his sleep. If you can hear a splash that isn't there, maybe he's hearing a sentence that isn't there either." They agreed to run a paired test at the fog line with two stopwatches, theirs, to see if the delay followed the person or the place. They did not say it aloud, but both feared the answer.

At the town hall, Noa Hadar and Dalia Shalev played the voice memo from the well, and they marked each splash on paper. Noa wrote down her own timings, and Dalia wrote hers, and when they compared, they found they both placed the splash at about three seconds after release. But Liesl's spoken cue on the same recording was a full second later. "It's in her hearing," Noa said quietly, and Dalia nodded, but she wrote in her notebook, "In her hearing, or in something else."

Other things happened that day, though the well claimed the morning. Meir Golan found a seventh stone block in the quarry, where the survey listed six. Zipporah Gefen found it too, and Phineas Tamir. They stood around it, counting the blocks again, then the chairs, and the scarves. At the mill, Uzziah Peretz and Joel Gefen sat a long while comparing their measurements, and they did not agree. Devorah Eshel and Yael Kfir did the same at the mill, and they also did not agree. At the square, Ezra Peretz and Hillel Kfir came to blows over nothing much, and the guards separated them, their faces red, their fists still clenched.

Fernando, the instrument maker, fell ill with the valley fever and lost three days to it. Levi Ben-Ami the gardener fell ill too, and both were put to bed with sleep and complaint. In the town hall, three babies were born: Gad Ofer, Ophir Eshel, and Batsheva Segal. Each of them, when they slept, spoke the words no one had taught them: "the fog is just fog." And in the hall, three people died of old age, Eliana Erez at 103, Perez Raz at 104, and Rimon Kedem at 92. In their last days, people said they were asleep.

In the afternoon, a guard at the east road turned Gavriel Dagan back at the fog line, and another turned Yarden Eshel back. A guard at the south road turned Isaac Kfir back, and Eliana Nir. Each reminded them that the Council preferred people to stay at their work, and each turned and walked home, the fog unmoved.

By evening, Liesl sat in her shop, the stopwatch before her on the bench. She had proved that the delay was in her, and she had proved that she heard a second splash that no one else heard. She turned the stopwatch over in her hand. If the sound was in her, then the fog was just fog. But she did not believe it. She set the stopwatch down and went to the door, looking out at the dark street. The well was far away, but she could almost hear it, the water still and patient, waiting for the next stone.
