The Frequency of Unseen Corners

In the dusty outskirts of Maiduguri, where the harmattan wind carried whispers of forgotten things, twelve-year-old Tunde decided he was too old to share a room with his younger brother, Emeka. Their family had been relocated to a government housing estate, a row of identical, sun-baked bungalows, and their unit was a cramped three-bedroom affair. Tunde’s sister, Fatima, had her own room, while he and Emeka shared a claustrophobic space, their beds pushed against opposite walls, their arguments echoing off the peeling paint. Then there was the detached two-bedroom house at the end of the compound. It had sat empty for over two decades, its windows like hollow eyes, its porch a graveyard of dead leaves. The estate manager had recently patched its roof and whitewashed its walls, a half-hearted attempt to make it habitable, but no one had dared to claim it. Tunde, however, saw an opportunity. He would have his own kingdom, a silent fortress away from his siblings’ noise.

He moved his meager possessions—a mattress, a mosquito net, a stack of dog-eared comics—into the larger of the two bedrooms. The air inside was thick with the smell of old concrete and something else, a faint, acrid odor that he couldn’t quite place. The first week was bliss. He slept soundly, the silence a luxury he had never known. But then, a neighbor’s son gave him a battered stereo system, a relic of the 1980s with a cassette deck and two towering speakers. Tunde, intoxicated by the power of sound, blasted music at full volume from dawn till dusk. The walls vibrated, the windows rattled, and the muffled thump of bass became his heartbeat. That’s when the trouble began.

Nights turned restless. He would lie on his mattress, the music still ringing in his ears, and yet, beneath it, he began to hear things. At first, it was just a subtle shift, like the settling of the foundation. Then, it was the creak of a floorboard in the empty room next door, followed by a rhythmic tapping from the ceiling. He tried to ignore it, attributing it to rats or the wind. But the sounds grew more insistent. One night, he switched off the stereo, and in the sudden silence, he heard a clear, distinct whisper: ‘Turn it up.’ He froze, his heart hammering. He told himself it was his imagination, but the voice had sounded so close, as if someone had been standing right behind him.

Desperate for sleep, he kept the music playing, but even at high volume, the sounds persisted. They seemed to synchronize with the bass, creating a dissonant harmony. He would wake up with his ears ringing, a headache throbbing behind his eyes. He began to see things in his peripheral vision—a flicker of movement near the door, a shadow that didn’t match the furniture. He would spin around, but nothing was there. The fear gnawed at him, but he was too proud to return to his parents’ house, too stubborn to admit defeat.

One evening, as the sun bled orange over the rooftops, he decided to test the other room. He had never entered it, too creeped out by its peeling, water-stained wallpaper. But that night, he was determined to find the source of the noise. He pressed his ear against the cold door, and he heard it again—a low, rhythmic hum, like a dying electrical transformer. He pushed the door open. The room was bare, save for a single, dust-coated chair in the center, facing a blank wall. On the wall, someone had scratched a series of tally marks, hundreds of them, stretching from floor to ceiling. The humming grew louder, and the air around him seemed to vibrate.

He backed out, slamming the door shut, and that night he slept with the stereo blaring louder than ever, the bass thumping so hard that the speakers’ cones nearly tore. But the sound drowned out the whispers, and for a few hours, he found oblivion. When he woke, the stereo was gone. In its place, on the floor, was a cassette tape, unmarked, its plastic casing cracked. A note, written in a shaky, childlike hand, was taped to it: ‘Play this, or I will find you.’ Tunde’s blood ran cold. He didn’t touch the tape. He threw it into a corner, but that night, the humming returned, louder, and the floor beneath his mattress began to pulse with a slow, deliberate rhythm, like a heartbeat.

He tried to leave, once. He packed his bag and walked to the front door, but when he turned the knob, it wouldn’t budge. He pushed harder, then realized the door was not locked—it was sealed, as if the frame had been fused with the wall. Panic seized him. He ran to the window, but the glass was opaque, showing only a distorted, swirling darkness. The humming was all around him now, a constant, unescapable drone. He sank to his knees, covering his ears, but it did no good. The sound was inside his head, a frequency that resonated with his very bones.

Days passed, or maybe hours. He lost all sense of time. He would drift in and out of consciousness, seeing flashes of a figure—gaunt, with hollow eyes, its mouth stretched wide in a silent scream. The figure would stand in the doorway, tilting its head as if listening, then it would point a long, bony finger at the cassette tape. On the third day, or the fifth, Tunde surrendered. His hands trembling, he picked up the tape, inserted it into the stereo that had mysteriously reappeared, and pressed play.

A discordant melody filled the room, a twisted lullaby of off-key piano notes and distorted strings. And then, a voice, not human, but layered, as if a hundred voices were speaking in unison, began to whisper over the music. ‘Good boy,’ it said. ‘Now, we will never be alone again.’ Tunde looked up, and in the corner of his eye, he saw shadows coalescing into a shape. The figure from his dreams stepped forward, and behind it, countless others, all with the same hollow eyes, all reaching for him. He screamed, but the sound was swallowed by the music, which grew louder and louder until it was the only thing in existence. The last thing he saw was the cassette player’s red light flickering like a dying star.

Weeks later, a new family moved into the estate. The boy, a ten-year-old named Musa, was intrigued by the empty house at the end of the compound. The door was ajar, and he peeked inside. The room was bare, save for a single stereo system and a cassette tape on the floor. The tape’s label was blank, but as Musa picked it up, he could have sworn he heard a faint, rhythmic whisper coming from the speakers, even though the stereo was off. He shrugged, smiled, and ran to his mother to ask if he could have it. She said yes, and Musa happily carried the stereo to his room, not noticing the faint tally marks that had begun to appear on his bedroom wall. That night, as he pressed play, he wondered why the music sounded so familiar, as if he had heard it all his life. And in the silence between tracks, he heard a soft voice say, ‘Welcome home.’
