My father was the night janitor at the St. Elmo Veterans’ Hall, a squat brick building that had once been a tuberculosis sanatorium. The halls smelled of pine disinfectant and old dust, and the ceilings were so high that our footsteps echoed like distant thunder. He’d let me tag along on his shifts, and that summer, my friend Mira came with me. We were thirteen, bored, and the building was a playground of forbidden doors and half-lit corridors.
One night, while Dad was scrubbing the kitchen, we found ourselves in what the old-timers called the ‘Blue Room.’ It was a banquet hall with a long, polished bar and dozens of round tables draped in navy cloth. Cobwebs jeweled the chandeliers, and the room felt colder than the rest of the building, as if the heat had never reached it. We were pretending to be waitresses, sliding between tables, when I noticed the liquor room door—a steel-reinforced thing with a padlock that hung loose. I tapped three times on the metal, a silly rhythm: tap-tap-tap. The sound died, and for a second, there was nothing. Then a reply came: tap-tap-tap-tap. A different beat. Not an echo. Something on the other side was repeating me, but with its own intent.
I froze, my hand still against the cold metal. I turned to Mira, who had gone pale, her dark eyes wide. ‘You heard that, right?’ I whispered. She nodded, her mouth a tight line. Without another word, we bolted for the doorway. Just as we crossed the threshold, something cold and impossibly strong latched onto Mira’s ankle. She shrieked, a sound that tore through the silent hall, and yanked herself free. Her sneaker caught on the jamb and she stumbled into the hallway, and we kept running until we burst into the cloakroom across the hall. We slammed the door and pressed ourselves against it, breathing in ragged gasps.
When we dared to look back through the crack, the hallway was empty. The Blue Room’s door stood ajar, a black maw of darkness. Mira pulled up her pant leg, and I saw it: a handprint of raw, crimson welts wrapped around her ankle, the fingers splayed and distinct. The skin was blistering, and the marks were already turning a sickly purple. ‘It grabbed me,’ she said, her voice shaking. ‘It felt like a dead person’s hand—cold and hard.’
We didn’t tell my dad. We couldn’t. He would have laughed it off or made us clean the room as punishment. So we stayed in the cloakroom, listening to the creaks and sighs of the old building, until his shift ended. But the marks wouldn’t fade. They turned into permanent bruises, and Mira started having nightmares—she’d wake up screaming about a man in a dark coat who whispered her name from behind a locked door.
A month later, I went back alone, in daylight. I walked into the Blue Room, my heart hammering, and I looked at the liquor room door. The padlock was now firmly closed. But on the floor, in front of it, was a small pile of white crystals—salt, like someone had spilled it there. I touched the door, and it was warm. Not cold like that night, but warm, like a body had been leaning against it. I left without telling anyone, but I couldn’t shake the idea that whoever had tapped back was still in there, waiting, and that the salt was a warning.
Years later, when I was in college, I got a call from my dad. He was closing down the hall for good, and he’d found something in the liquor room during his last cleanout. He said the room was empty except for a single, rusted key and a photograph on the floor. The photograph was of a man in a military uniform, and on the back, in faded ink, was written: ‘For the one who taps in the dark.’ I never went back to St. Elmo’s. But sometimes, when I’m alone in a quiet room, I hear three taps—and then four, answering from somewhere unreachable. And I know, whatever it was, it’s not finished with me.
