The Silent Signal

Letter 30 of the Book of Forgetting

The town hall clock read 11:52 when I spread the printouts across the long table. Noa Hadar came in with her bag, set it down, and pulled out a thin stack of papers.

"The click test is clean," she said. "Her voice lands right on the click every time. Twelve for twelve."

"And the well recording?"

She slid another sheet toward me. "Her 'now' lags about a second after the splash I marked. Every time."

I put the two pages side by side. "So her timing is fine on pure clicks but lags exactly on the well splash. That's not her ears. It's the well."

"Or something about the splash itself," Noa said. "The click is a dry sound. The splash is wet. Maybe it's the frequency."

"Then we test that. One more drop, but this time I give her a silent signal to say 'now' after she hears the first splash. No sound cue at all."

Noa looked at the printouts. "You mean time her reaction without any audio trigger."

"Exactly. If she waits a second even when she only has my hand signal, then it's not tied to the well sound. It's something else."

She nodded slowly. "That would clean up the variable. I'll set up the recorder and mark the splash myself."

"Good. And bring her voice onto the same track—I want to see where her cue lands relative to the recorded splash."

"I'll run the click test again with her saying 'now' out loud, record both on the same track. That should settle it."

The door opened. Garrin Zohar came in, his cardigan buttoned to the neck, a length of grey cloth folded over his arm.

"Liesl agreed to the cloth screen," he said. "Same track, both cues. She wants to see the playback herself."

"She's at the well now?" I asked.

"Waiting."

The old well stood grey at the south edge, the fog flat and low. Liesl Kfir stood with her arms crossed, her stopwatch on the wall beside her. Garrin set up the cloth screen three meters from the well mouth.

"You want to record the stone and my voice on the same track," Liesl said, "and see if I call out a full second after."

"Exactly," Garrin said. "If your cue lags even when you can't see, then it has to be the well itself."

"And if the second splash doesn't show up on the recording at all?"

"Then we'll have something even stranger. But we'll finally have it settled."

I held up my hand. "Before that—I want to try something. Noa drops the stone. Your back is to the well. I raise my hand. When you hear the first splash, you say 'now.' But you won't see me raise my hand. Noa will signal me, and I'll raise it, but you'll be facing away. You'll only have the sound."

Liesl turned to face me. "You're testing whether I wait a second out of habit."

"I'm testing whether the lag follows your hearing or your expectation."

She was quiet a moment. Then she nodded. "All right. But I want to see the track."

Noa set up the recorder at the well mouth. Garrin tied the cloth screen between Liesl and the well. I stood to her left, where she could see my hand on the edge of her vision.

Noa picked up a stone. "Ready."

Liesl turned her back. Noa raised her hand. I raised mine. The stone fell. The splash came clean.

Liesl said "now."

Noa pressed stop. She played it back. The splash sounded, then Liesl's voice, a full beat later.

Noa looked at the waveform on the recorder's screen. She counted with her finger.

"Her cue lagged one point one seconds after the splash I marked," she said.

Liesl turned back around. "Play it again."

Noa did. The splash. The pause. Liesl's voice.

"Now play it once more," Liesl said. "And tell me what you hear."

Noa played it a third time. The splash. The pause. Liesl's voice.

"I hear one splash," Noa said.

Liesl stared at the well. "I heard it twice. Same as always. About a second after the first."

Garrin wrote something in his notebook. "The lock screen test was clean this morning. Your hearing-to-hand speed is normal. But here, with no visual cue, you still lag."

"And I still hear the second splash," Liesl said. "So it's not the cloth. It's not expectation. It's the well."

Noa shook her head. "But the track doesn't have it. The second sound isn't in the air."

Liesl picked up her stopwatch from the wall. "Then it's in me. And it follows me. And I'm the only one who hears it."

She walked off toward the plaza. The fog held its grey light. Noa marked the track with a pencil, and we all stood there with nothing left to measure.
