The Registry of Unclosed Locks

The Galbraith Building was a monument to a bygone era, its marble floors and brass fixtures echoing a time when commerce felt like ceremony. It had been a department store, then a hospital, then a derelict shell before the city bought it for administrative offices. But the basement still held the old security hub, a warren of dusty monitors and a console that looked like the bridge of a submarine.

I was a new hire, a night guard assigned to the overnight system test with a veteran named Elias. Elias was a lean, gray man who spoke in measurements: the width of a doorframe, the decibels of a fire alarm, the exact number of steps from the loading dock to the freight elevator. He’d worked the Galbraith for fifteen years, and he had a personal rule: never walk the floor alone at night. Tonight, we had to.

Our task was simple. I would take the walkie-talkie and traverse the building, tripping each motion sensor and door alarm in sequence. Elias would stay in the security hub, log each activation, and confirm over the radio. We started on the fifth floor, where the old hospital wings had been converted to storage for archived court records. The air there was thick with the smell of paper dust and disinfectant.

My first stop was the records room. I pushed the door, and the alarm chirped once, then blared. For a moment, the sound was deafening, reverberating off the metal shelves. I keyed the mic. ‘Ground zero, records room, motion sensor north corner.’

Elias’s voice crackled back, dry as old leather. ‘Copied. Moving to two?’

‘Affirmative.’ I walked the narrow aisle between shelving units, the red light of the sensor pulsing above me. As I reached the far end, I heard something behind me—a soft, almost imperceptible rustle, like fabric or paper shifting. I spun, but the room was empty, still. I told myself it was the air conditioning, but the building had been on low power all night; the air was still as a held breath.

I proceeded to the stairwell. The alarm on the second-floor door was next, a magnetic contact that I had to trigger by breaking the seal. I pulled the door open, and it groaned on its hinges. That was when I noticed the main exit doors at the far end of the hallway were slightly ajar. They were supposed to be locked and alarmed, but they clearly weren’t. In fact, they weren’t even shut properly; the pneumatic closer had failed. I reported it to Elias.

‘Exit doors, main east stairwell, not sealed. I’m going to reset them and trip the alarm.’

‘Copy. Note that in the log. But be careful, some of those doors have been known to have sticky switches.’

I walked down the corridor, and as I approached the glass doors, I saw a figure on the other side. A woman in a long, outdated coat, standing perfectly still on the stairwell landing. She was facing away from me. I froze, my heart kicking. Was it a homeless person who had wandered in? But the building had been secured all night.

‘Hey!’ I called out. ‘You can’t be in here.’

The figure didn’t move. It didn’t turn. I took a step closer, and then I realized the glass was not reflecting anything—the stairwell was dim, but I could see through to the brick wall on the other side. There was no one there. The coat was a trick of the light, a column of shadow. I shook my head, laughed at myself, and reset the door. The alarm chirped and then fell silent. I keyed the radio. ‘East stairwell, exit door, reset and alarm tripped.’

‘Copy, I have it logged. Next is the second-floor motion sensor near the old cafeteria.’

‘On my way.’ As I walked, I couldn’t shake the feeling of being watched. The Galbraith had a history, and Elias had told me one of the older tales over our first coffee break: how a maintenance man had died in the boiler room back in the ’70s, and how a nurse had hung herself in a supply closet on the third floor. He’d laughed it off, but then added, ‘Just don’t go looking for them. They usually leave you alone.’

But tonight, they weren’t leaving me alone. As I passed the nursing station on the second floor—now a dusty cubicle farm—I heard a typewriter clatter from a dark office to my left. I stopped, listened. No one had been on that floor before me. I shone my flashlight through the doorway. The room was empty, but on the desk, a roll of adding machine paper was unfurled, half-covered in numbers, as if someone had been interrupted mid-tally.

I felt a cold dread settle in my stomach. I keyed the radio, and my voice came out higher than I intended. ‘Elias, you there?’

‘Yeah, go ahead.’

‘Check the camera feed for the second floor, office 2C. I think someone’s been here.’

There was a long pause, static, then: ‘I’m looking at the feed now. It’s just you, kid. The floor’s clean.’

‘You sure? I heard a typewriter.’

‘I hear the building settling all the time. Don’t let the stories get to you. Two more alarms and we’re done.’

I breathed in, out. He was right. I was letting the old tales spook me. I moved to the next alarm, the fire exit on the landing above the loading dock. As I climbed the cement stairs, my footsteps echoed too loudly, too wetly, as if I were walking on a different surface. I looked down—the floor was dry, but the sound was like splashing.

I reached the landing and found the fire exit door. It was a solid metal door with a push bar. I pressed it, and the alarm screamed for a moment, then cut off. I reported it. ‘Fire exit landing, alarm tripped.’

‘Copy. Last one: the motion sensor in the basement corridor near the old security hub.’

‘That’s close to you. Want me to detour?’

‘Nah, I’ll just watch you on the camera. Keeps me entertained.’

The basement was a maze of pipes and old machine rooms. The corridor was lit by a single swinging bulb, casting long shadows that moved as the light swayed. I could see the security hub’s door at the end, and Elias’s silhouette through the window, hunched over the console. I walked toward it, and as I passed a large, rusted iron door marked ‘BOILER ROOM – AUTHORIZED PERSONNEL ONLY’, I heard a metallic ping from within, like a wrench dropped on a pipe.

I hesitated. The boiler room was supposed to be sealed. I turned to the door, and I could see a faint, flickering light through the slat at the bottom. I reached for the handle, and the door swung open on its own, creaking inward. The room was pitch black, but I could hear a rhythmic hiss, like steam escaping.

‘Elias,’ I called over the radio. ‘There’s something in here.’

No response. I called again. Static. I looked toward the hub, but Elias was gone from the window. Panic began to rise. I walked to the hub door and pushed it open. The room was empty. On the console, the logbook was open to the last page, and written in sharp, angular handwriting that was not mine nor Elias’s, was a list of alarms, each one perfectly timed to when I had triggered them, but the last entry read: ‘Third alarm at 3:33 AM – the walker has been noted.’ But I didn’t trigger the third alarm yet. And it was only 2:47.

Then I heard a sound behind me—the click of the hub door closing. I spun. Elias stood there, his face pale, his eyes wide. He looked at me, then at the logbook, and his jaw tightened.

‘It’s not a game anymore,’ he said, his voice low. ‘We need to leave now.’

‘Why? What’s happening?’

He pointed to the bank of monitors. Every single camera feed now showed the same scene: a figure in a long, old-fashioned coat standing in the middle of the corridor I had just walked, but the face was a blur of static. And as we watched, the figure began to walk toward the hub, closer with each step, and I noticed that it moved like it was walking on a floor that was not level, but advancing in a way that made my stomach flip.

‘That’s the registrar,’ Elias said. ‘It writes down the names of everyone who disturbs the locks. It’s been here since the hospital days. It doesn’t like to be kept waiting.’

‘Waiting for what?’ I asked, my voice barely a whisper.

He looked at me, and for the first time, I saw true fear in his eyes. ‘For the last alarm to be set off. You, me, or it—whoever presses the button first, the other becomes a permanent entry in the ledger.’

His hand inched toward the console. On the monitor, the figure was now at the door, its hand reaching for the handle. I saw Elias’s finger hover over the red button labeled ‘ALARM 12 – BASEMENT’. He was going to trigger it and leave me to face the thing. But in a flash of instinct, I lunged and tackled him away from the button. We crashed to the floor, and the walkie-talkie in my belt squealed with a burst of static, then clicked, and a voice—dry, like old paper—said, ‘Alarm twelve: basement corridor. Thank you.’

The hub door swung open, but there was no one there—just the empty corridor, the swinging bulb casting shadows. I looked at Elias, who was breathing heavily, his face ashen. The logbook on the console still lay open, but the handwriting had changed back to normal—Elias’s and mine. The last entry, in my own hand, read: ‘Completed system test, all alarms functional. End of shift.’

I never worked the Galbraith Building again. Elias quit the same week. And every so often, when I pass the old building at night, I see a silhouette in the basement window, holding a pen, and I swear it looks up and waves. But I never look too long. Some locks are better left unopened, and some ledgers are best left unread.
