The 13th Floor

The Zenith loomed before me, a monolithic testament to human ambition and architectural audacity. Its glass and steel facade pierced the skyline like a defiant obelisk, daring the heavens themselves. As I stood at its base, craning my neck to glimpse its summit, a chill ran down my spine despite the warm summer evening.

"Impressive, isn't it?" A voice startled me from my reverie. I turned to see a man in his sixties, his silver hair neatly combed, his suit impeccable. "I'm Harold Weiss, the building manager. You must be the new structural engineer."

I nodded, extending my hand. "James Parker. Pleased to meet you, Mr. Weiss."

His grip was firm, but his hand was ice-cold. "Please, call me Harold. Shall we begin the tour?"

As we entered the lobby, I couldn't shake the feeling of being watched. The high ceilings and polished marble floors seemed to amplify every sound, our footsteps echoing ominously.

"The Zenith has quite a reputation," I ventured, trying to break the uncomfortable silence.

Harold's lips curved into a thin smile. "Oh? And what have you heard?"

I hesitated, not wanting to offend my new client. "Well, there are rumors about its... unique design. The missing thirteenth floor, for instance."

Harold's eyes narrowed almost imperceptibly. "Ah, yes. A common superstition in architecture. We simply... skipped the number. Nothing more."

We reached the elevators, and Harold pressed the call button. As we waited, I noticed something odd about the panel.

"The button for the thirteenth floor is missing," I observed.

Harold's smile didn't reach his eyes. "As I said, we skipped it. Shall we start with the lower levels?"

As we toured the building, I couldn't shake the feeling that something was off. The temperature seemed to fluctuate wildly between floors, and more than once, I caught glimpses of movement in my peripheral vision, only to find empty hallways when I turned.

"Harold," I said as we reached the twelfth floor, "I can't help but notice some... irregularities in the building's design. The temperature variations, for instance."

Harold's face remained impassive. "Old buildings have their quirks, Mr. Parker. Nothing to be concerned about."

I pressed on. "And the original blueprints? I'd like to review them if possible."

For a moment, I thought I saw a flicker of fear in Harold's eyes. But it was gone so quickly, I might have imagined it.

"I'm afraid those were lost in a fire years ago," he said smoothly. "But I assure you, everything is up to code."

As we stepped onto the fourteenth floor, a wave of cold air hit me like a physical force. I shivered involuntarily.

"Good God, it's freezing up here," I muttered.

Harold seemed unfazed. "Is it? I hadn't noticed. Perhaps we should check the thermostat."

As we walked down the corridor, the lights began to flicker. A low, distant hum filled the air, growing louder with each step.

"What's that sound?" I asked, my unease growing.

Harold cocked his head, listening. "I don't hear anything, Mr. Parker. Are you feeling alright?"

Before I could respond, a blood-curdling scream echoed through the hallway. I spun around, heart pounding.

"Did you hear that?" I gasped.

Harold's face remained eerily calm. "Hear what, Mr. Parker? Perhaps we should conclude our tour for today. You seem... tired."
