Nabil's family moved into the old stone house on the outskirts of Salt at the end of summer. It was a spacious house with tall windows and thick walls, and it carried a smell of old bread that no one could place.

The father said, carrying in the first box, "It's cheap because nobody wants it. People are afraid of quiet houses."

It wasn't the quiet that bothered nine-year-old Yazan. The quiet felt to him like a curtain waiting to be drawn back. On the third night, it was.

Yazan woke at two in the morning to a faint sound coming from the wall beside his bed. A slow melody, as if a woman were humming to a small child. The words weren't clear, but the rhythm was warm and sorrowful at once.

He pressed his ear to the wall. The sound grew clearer: "Sleep, my love, sleep... my missing son, sleep..."

In the morning Yazan told them what he'd heard over breakfast. His father laughed and said it was the pipes, and his mother said it was a dream after a tiring day. But Yazan was certain. Pipes don't know how to sing.

The next night Yazan recorded the melody on his mother's phone. In the morning he played it for them. His mother listened to the humming for a few seconds, then gripped her husband's arm tightly. She said, "That's not a pipe."

The father said nothing for a moment. Then he said, "I'll knock on the wall."

The father knocked on the wall all around Yazan's room. In most spots the sound came back solid. But at a corner beside the bed, half a meter up from the floor, the echo was different: hollow.

The father brought a small hammer and a chisel and began carefully removing the plaster. Beneath the first layer was stone. And beneath that, a stone set in differently from the rest. He lifted it out, revealing a small cavity like a hidden shelf. Inside it sat a rusted metal box, wrapped in a piece of cloth.

The mother opened the box with trembling fingers. Inside she found an old cassette recorder, of the kind that uses tapes, and three tapes, each labeled in shaky handwriting: "For Khalil."

A small folded note lay beneath the tapes. The mother read it aloud:

"To my son Khalil. If you've found this, then you've come back home. I recorded these tapes so you could hear my voice if I'm not here when you return. Your mother, Khalil's mother."

Everyone sat on the floor of the room. No one spoke.

Yazan finally said, "So the sound wasn't scary. It just wanted to be heard."

The mother searched for the house in the municipal records and asked around the neighbors. From an elderly woman in the neighborhood she learned that Khalil's mother had lived here for many long years, that her son had gone abroad for work in his youth, and that news of him had stopped coming after a few years. The mother had died two years ago, and no one knew his address anymore.

The father said, "We have to find him."

It took weeks. They wrote to acquaintances, posted on expatriate pages online, and asked at the mosque and the bakery. Finally, a woman from a distant city replied to an old post: her husband was named Khalil, from Salt, and he had dreamed for years of finding his mother's house.

Khalil arrived in late autumn. A man in his sixties, his hair white, his eyes swollen from sleeplessness. He stood in front of the house for a full minute before going in.

Nabil handed him the box without a word. Khalil sat on the front step and started the first tape. A hiss came from the recorder, then a woman's voice, speaking gently:

"Khalil, my darling... today I made the bread you love..."

Khalil wept in silence as he listened. No one said anything. The mother made him tea, and Yazan sat beside him holding his knee.

After an hour Khalil lifted his head and said, "I thought she was angry with me. Because I never came back."

Yazan said, "She wasn't angry. She was singing to you."

Khalil took the tapes and left, after the father insisted he stay for dinner. From that night on, Yazan never heard the melody again. But the smell of old bread, the one no one could ever place, still appears sometimes on Friday evenings by the kitchen door — faint, warm, as if someone had just finished baking and left the door open for whoever might pass by.
