The Siren

The opening follows the childhood question that will remain with Jan—and with Eleanor—for years. This excerpt contains the prologue and the beginning of the first chapter.

The Siren

At first, the siren was a thin, high line cutting through the air.

Jan lifted his head. The car was still far away, but the sound had already reached him. He stood beside his father on the pavement, holding his hand and listening harder than he looked.

“Do you hear it?”

“Everyone hears the siren.”

Jan shook his head. “Not that.”

The note tightened as the vehicle approached. Then the car passed, and the sound opened into something lower.

“—aaaaaaaaawwwww.”

Jan let go of his father’s hand. “Why did it change?”

“Because the car is moving.”

“I know. But did the sound change?”

His father watched the ambulance disappear around the corner. He was silent long enough for the question to remain a question.

Jan listened to the fading note. “Maybe we hear it differently because it has to reach us.”

His father looked down at him. Pride crossed his face, followed by something Jan was too young to name.

“Remember that,” he said. “By the time something reaches us, it has already had a journey.”

Between the high note and the low one, there had been a moment almost too small to hear.

Brno was still warm.

It was October. The leaves had turned, and the light had already lowered, but the cobblestones still held the summer in them. The air had not quite committed to cold.

Eleanor Voss had stopped before a shop window she was not looking at.

The conference had ended an hour ago. She had a train to Vienna at nine. Between her and the train was an hour and a half she did not know how to fill, so she walked.

An ambulance passed somewhere beyond the corner. Eleanor heard the note tighten, then open into something lower. By the time she located the sound, the vehicle was already gone.

A boy stood beside his father a few metres away, still facing the empty street. Eleanor had no Czech. She could not follow the words, but she saw the boy lift one hand toward the direction the sound had travelled and then tilt his head, checking what he had heard against something inward.

The expression was familiar. Eleanor had a photograph of herself at seven wearing it. The picture lay in a desk drawer she had not opened in years.

She approached.

The father looked up, measuring the distance between his son and a stranger.

“Does he speak English?” she asked.

“A little.”

Eleanor crouched far enough away that the father did not have to move closer.

“You were listening to the ambulance. Why did the sound change?”

The father translated. The boy answered quickly, then stopped and tried again in careful English.

“The car moves. The sound comes to us.”

He frowned at the sentence, dissatisfied with what the grammar had made smaller.

“Did the sound itself change?” Eleanor asked.

The father translated only part of the question before the boy shook his head.

“It does not know,” he said. “We hear it after.”

Eleanor held still. The answer was not a theory. It was not even technically complete. What mattered was the division the boy had made without being offered it: source, journey, receiver.

She did not correct him.

From her bag she took a small working notebook. Equations and conference names filled most of the visible page. She tore out a blank sheet and wrote one question.

Do you think the sound knows where it’s going?

The boy took it. His lips moved over the English without sound.

“Jan,” his father said gently, pointing toward the crossing. They needed to move.

Eleanor repeated the name once in her head.

“Conference?” the father asked.

“Physics,” she said.

She continued toward the station. She did not look back, but she slowed long enough to hear the father read the question aloud and the boy repeat it.

On the train to Vienna, Eleanor opened her notebook beneath the conference notes.

Brno. Jan, perhaps eight. Siren. Distinguished a change at the source from the form in which the signal reached him. Did not accept the first explanation as the end of the question.

She paused, then added a final line.

Do not answer too quickly.

She marked the page with the date and closed the notebook. It was not a promise to find him. It was only a decision not to lose the question—or the person who had asked it.
