Emma discovered Apartment 4B existed when she heard Frank Sinatra through her wall at 3 AM.
She’d lived in the Marigold Building for six months and never really noticed her neighbors. She worked from home, kept odd hours, ordered everything from delivery apps. The people on the other side of her walls were abstractions — footsteps overhead, a baby crying somewhere downstairs, the occasional thump of furniture being moved.
But Sinatra at 3 AM was different. Sinatra at 3 AM was specific.
The music was coming from the wall behind her headboard. Not loud enough to be intrusive — she could only hear it when the city outside went quiet. But it was there, unmistakably: “Fly Me to the Moon,” followed by “The Way You Look Tonight,” followed by what sounded like the entire Rat Pack catalogue filtering through the old building’s thin walls.
She should have been annoyed. Instead, she found herself lying in the dark, listening.
The next night, same thing. Sinatra at 3 AM, soft and distant.
On the third night, Emma noticed something: the radio only played when she couldn’t sleep. She’d lie awake, mind racing, and twenty minutes later, Sinatra would start. Like the wall itself had sensed her sleeplessness and responded.
It was absurd. Coincidental. Not magical at all.
But on night four, unable to sleep and frustrated, she knocked softly on the wall behind her headboard. Three gentle taps.
The music stopped.
Then, unmistakably, three taps came back.
Emma’s heart jumped. She knocked again — a pattern this time: shave-and-a-haircut. A moment of silence. Then, through the wall: two bits.
She laughed out loud, surprising herself. Whoever was on the other side of 4B had rhythmic taste and a sense of humor.
The music started again — something different this time. Not Sinatra, but Ella Fitzgerald. As if her neighbor was asking: Is this better?
Emma knocked once in response: yes.
She fell asleep to “Summertime” and slept better than she had in weeks.
The nighttime ritual continued.
Emma would knock when she couldn’t sleep. The radio would respond with music — sometimes jazz, sometimes classical, once a full hour of Beatles songs that made her smile into her pillow. She never heard anyone moving in 4B, never saw anyone enter or leave. Just the music, just the knocks, just the strange, intimate communication of two insomniacs through a shared wall.
She started thinking of her neighbor as “the Radio Person.” She imagined them matching her sleeplessness hour for hour, keeping a vintage set tuned to stations that still played the old songs. She imagined someone elderly, maybe widowed, awake at odd hours because sleep no longer came easily.
She imagined knocking on their door.
But there was something precious about not knowing. About the mystery of it. About having a connection that existed only in rhythm and melody and thin plaster walls.
Then the music stopped.
One night, two nights, a week. Emma knocked, but no one knocked back. She pressed her ear to the wall and heard only silence.
On the eighth night, she couldn’t stand it anymore. She walked into the hallway, stood in front of 4B, and knocked on the door.
It swung open almost immediately.
The man was not what she expected. He was maybe sixty, silver-haired but fit, with kind eyes and slippers that had seen better days. Behind him, she could see a living room that looked like a time capsule: shelves of vinyl records, books everywhere, and in the corner, an old radio with a warm wooden case, softly glowing.
“You’re 4A,” he said, before she could speak.
“You know?”
“The knocks. I’ve been waiting for you to come by.” He stepped aside. “I’m Henry. Would you like to come in?”
His name was Henry Okonkwo. He’d been a jazz musician in his youth, had toured with bands whose names Emma half-recognized from her parents’ record collection. Now he was retired, widowed, living on stories and music and the peculiar insomnia that came with old age.
“I started playing the radio because I heard you pacing,” he explained, settling into an armchair while Emma sat across from him. “These walls, you can hear everything. I could tell you weren’t sleeping, so I thought… maybe music would help.”
“It did,” Emma said. “It really did.”
“Then I got sick.” He shrugged. “Nothing serious, but the hospital kept me for a week. I should have left a note on your door. I didn’t think anyone would notice.”
“I noticed.”
Henry smiled — a big, warm smile that made the whole room feel lighter. “In that case, can I offer you some tea? I have a feeling we have a lot of sleepless nights to catch up on.”
They became friends. Real friends, not just strangers connected by walls.
Emma helped Henry organize his record collection. Henry taught Emma the difference between bebop and swing. They had tea at 3 AM, which turned into tea at midnight, which eventually became Sunday dinners and birthday celebrations and the easy rhythm of people who’d chosen each other as family.
When Henry died — peacefully, in his sleep, at the age of eighty-one — he left Emma the radio.
She set it up behind her headboard, where his had been on the other side. And sometimes, late at night, when sleep wouldn’t come, she’d turn it on and let the old songs fill her apartment.
She liked to imagine Henry hearing them, wherever he was. Tapping along through some wall she couldn’t see.
Three knocks. Shave-and-a-haircut.
And somewhere, always: two bits.
