The Only Thing Moving on the Night Shift Was the Janitor's Radio

The bright lights at Sterling Tower are not just lights; they are a persistent, low-frequency hum that seems to reside in the ceiling panels. It is a constant, buzzing drone that defines the architecture of the night. At three in the morning, this sound is absolute. I work alone as the night security guard here, a position that requires a certain kind of temperament. My job is simple enough on paper: walk the perimeter, check the biometric locks on every heavy steel door, and keep an eye on the bank of monitors that look like a constellation of grayscale stars. I spend most of my shift listening to the rhythmic, dull tap of my own heavy-soled boots against the polished concrete floors and the muted thud on the industrial carpet. During the day, Sterling Tower is a living, breathing beast. It is full of people rushing to meetings, clacking keyboards, and complaining about the bitter coffee in the break room. But at night, the office changes entirely. It feels like a giant, sleeping monster. The dark cubicles are like rows of jagged, waiting teeth, and the empty executive suites feel like hollowed-out chambers where secrets go to hide. It is lonely, a specific kind of cold, hollow loneliness that seeps into your bones if you stand still for too long. It is a stillness that makes you start noticing every small creak of the building settling. Usually, the only thing that keeps the shadows from feeling too heavy is Gus. Gus is the night janitor, a man of few words and even fewer complaints. He is nearing seventy, I think, but he moves with the steady, practiced pace of someone who has spent decades working hard. He always carries an old, beat-up transistor radio. It is dented, covered in silver duct tape, and looks like it belongs in a museum, but the sound it puts out is glorious. Gus plays a mix of classic country and late-seventies rock. Hearing the faint, tinny strains of Johnny Cash or The Eagles echoing down the long, glass-walled hallways makes the building feel a little warmer and significantly more alive. It breaks the artificial silence and reminds me that I am not the only living thing inside this glass fortress. We usually share a brief nod or a muttered hello near the vending machines around midnight. He’ll ask me how the night is going, and I’ll tell him it’s quiet, just like always. He’ll usually crack a joke about how the building behaves better when the suits aren’t around. But one that day, things felt entirely different. The building was way too quiet. I did not hear the high-pitched whine of his industrial vacuum, nor did I hear the rhythmic, metallic squeak of his rolling supply cart. I paused in the lobby, straining my ears, expecting the familiar, comforting strum of an acoustic guitar to drift out from behind a corner. Nothing. Just the hum of the lights, which seemed louder than usual. I checked the break room first, assuming he might be taking a coffee break or tidying the kitchen area. The lights were off, and the room was freezing, the air smelling of stale espresso and sharp cleaning fluid. Gus was not there. His radio was gone, too. That was when the first prickle of unease started crawling up my spine. Gus never breaks his routine. He is a man of clockwork precision. If he is on the schedule, he is in the building. I pulled out my radio and tried to reach him on the maintenance channel, pressing the button until my thumb went white. I waited for his gravelly voice to come back with a response, but I only got back a hiss of static that sounded like dead air in a long tunnel. I felt a little silly, honestly. Maybe he had car trouble, or maybe he called in sick at the last minute and I just missed the memo. I looked at the logbook, but there was nothing written down for the evening shift. Still, the way the building felt tonight—it was different. It felt heavy, like the air had changed density. I started walking through the whole building, picking up the pace until my boots were echoing way too loudly against the walls. I checked the third floor, where the accounting firm keeps their files locked tight behind reinforced glass. I checked the fifth-floor conference rooms, pushing open every glass door to see if he was hunched over a desk or cleaning the whiteboards. The parking garage was a cavernous, dark pit, its concrete pillars looking like twisted trees in the dim emergency lighting. My flashlight beam cut through the dark, reflecting off the shiny paint of parked cars. I checked the fire exits, making sure every magnetic seal was green and secure, indicating no one had breached the perimeter. Everywhere I went, the building was empty. It was not just that Gus was gone; it was the way the absence felt. Nothing was where it should be. The cleaning supplies cart was usually left near the service elevator during his break, but it was nowhere to be found. The radio he always perched on the edge of his cart—the heart of this building at night—was missing. I felt a deep, gnawing unease because the geometry of my night had been broken. The structure of the shift had vanished. I started calling his name, my voice sounding thin and pathetic in the massive, hollow halls. Gus? You here? The sound just bounced off the mirrors and the glass panels, dying out quickly as if the office was swallowing my voice whole. I went to the janitor’s closet in the basement. The door was unlocked, which was strange in itself. Inside, his secondary supplies were untouched. The mop bucket was bone-dry. The shelf where he kept his lunch box was bare. There was no trace of him. I went back up to the main lobby and sat at my security desk, but I couldn't bring myself to watch the monitors. I felt like an intruder in my own workplace. The hum of the lights seemed louder now, mocking me with its mechanical indifference. I was supposed to be the one keeping this place secure, but I had never felt more vulnerable. I was just one person in a giant cage, searching for a ghost who had vanished into thin air, leaving me with nothing but the silence. I stared at the dark entrance, waiting for the swing of the door or the familiar shuffle of his boots, but the night remained stubbornly still. I spent the rest of the shift sitting in the dark, listening to the hum and wondering if I had somehow missed the world ending right outside those glass walls.
