The Billionaire Kept Me Captive

The building plans filed with the city of Austin showed forty-nine floors. Bellworth Tower has fifty-one.

I stared at the municipal records on my workstation screen, cross-referencing the original blueprints with the door access levels printed on my key card. The math didn't add up, and in my world, numbers that didn't add up meant someone was hiding something.

The original building permit, filed eighteen months ago, clearly outlined a forty-nine-story mixed-use tower. Residential floors forty through forty-nine, commercial and office space below. Standard high-rise construction for downtown Austin. But my key card granted access to floors forty-four through forty-nine, while Caspian's office occupied the fiftieth floor, with his private residence on what the elevator buttons labeled as fifty-one.

Two floors that didn't exist on paper.

I pulled up the construction modification requests, my fingers flying across the keyboard. There it was—a single amendment filed six months into construction. The date made my breath catch: March 15th, exactly three days after Caspian had officially assumed control of Bellworth Corporation from his father.

The modification was vague, buried in technical jargon about "structural optimization" and "mechanical system integration." But the result was clear—two additional floors had been added to a building that was already approved and under construction. Floors that the city of Austin had no record of.

I leaned back in my chair, processing the implications. In corporate auditing, phantom assets usually meant one thing: money laundering. But phantom floors in a building? That suggested something far more sophisticated.

My phone buzzed—the new one Caspian had given me. A text from an unknown number: "Ms. Garcia, your floor access permissions have been updated per security protocols. Please contact building management with any questions."

I hadn't contacted anyone about floor access. I hadn't even mentioned the discrepancy to anyone.

He was watching. Real-time monitoring of everything I accessed, every search I made, every file I opened. The realization sent ice through my veins, but it also confirmed what I'd suspected—whatever was on those missing floors was important enough to trigger automated surveillance alerts.

I saved the building records to my encrypted offline partition, then cleared my browser history. If Caspian wanted to play games with phantom floors, I'd give him something to monitor.

I opened a new tab and searched for "Austin building code violations reporting process."

The elevator ride to the forty-seventh floor felt longer than usual, each floor number lighting up like a countdown. When I reached my destination, I walked directly to the emergency stairwell, my heart hammering against my ribs.

The stairwell was pristine white concrete, each floor clearly marked with large black numbers. Forty-seven, forty-eight, forty-nine... and then nothing. The stairs simply ended at a blank wall marked "Emergency Exit - Roof Access Only."

I pulled out my phone and took pictures, the camera flash bouncing off the stark walls. No door to the fiftieth floor. No access point to the fifty-first. According to this stairwell, the building ended at forty-nine, exactly as the city records indicated.

But I'd seen Caspian's office. I'd ridden the elevator to floors that didn't officially exist.

I made my way back to the elevator bank, studying the emergency evacuation map mounted beside the call buttons. The diagram showed all fifty-one floors, but the top two were labeled differently: "50 - Executive Administrative" and "51 - Mechanical Systems - No Personnel Access Required."

A mechanical floor that occupied an entire level of a luxury high-rise? In a building with a private penthouse residence? The designation made no sense from an architectural standpoint.

I photographed the evacuation map, then pressed the elevator call button. When the doors opened, I stepped inside and examined the floor selection panel more carefully. Buttons for floors one through forty-nine were standard brushed steel. But fifty and fifty-one were different—black composite material with what looked like RFID sensors embedded in the surface.

I pressed my key card against the fifty-first floor button. Nothing. No light, no response, no movement from the elevator. I tried holding the card against the sensor for several seconds. Still nothing.

The elevator began its descent without my input, stopping at the forty-fourth floor where my room was located. The doors opened with a soft chime, but I didn't move. Someone else was controlling this elevator remotely.

I stepped out slowly, my skin crawling with the sensation of invisible eyes tracking my every movement. The hallway stretched in both directions, elegant and empty, but I could feel the weight of surveillance pressing down like a physical presence.

That evening, I found myself in Bellworth Tower's private bar on the forty-sixth floor, nursing a glass of wine I couldn't taste and staring out at the Austin skyline. The space was all dark wood and leather, designed to project old-money sophistication, but it felt more like a gilded cage.

"You look like someone who's discovered something interesting."

I turned to find a man approaching my table, his smile too wide, too perfect. Tall and lean with silver-touched temples and a face that belonged in a cologne advertisement. His suit was impeccably tailored, and his handshake was firm without being aggressive.

"Dominic Sable," he said, settling into the chair across from me without invitation. "Caspian's COO. And you must be the auditor who's been causing such a stir."

"Wren Garcia." I kept my voice neutral, but my mind was already cataloging details. His watch caught the bar's ambient lighting—a Patek Philippe Nautilus, easily worth two hundred thousand dollars. Expensive taste for a chief operating officer, even at a company like Bellworth.

"Caspian mentioned you'd be staying with us for a while." Dominic signaled the bartender, who immediately began preparing what was obviously his regular order. "Unusual arrangement. He doesn't typically invite outsiders to live in the building."

"I'm not exactly here by choice."

Dominic's laugh was practiced, corporate-smooth. "Few of us are, when it comes to Caspian's decisions. But he has his reasons. He always does."

The bartender delivered a crystal tumbler filled with amber liquid—top-shelf whiskey, judging by the reverent way it was presented. Dominic took a sip and studied me over the rim of his glass.

"You know," he said conversationally, "most auditors focus on the numbers. Revenue streams, expense reports, the usual financial archaeology. But you seem more interested in... architectural details."

My blood turned cold. He knew about my building research, which meant Caspian had shared my digital surveillance reports. How many people in this building were monitoring my every move?

"Buildings tell stories," I said carefully. "Sometimes more interesting ones than spreadsheets."

"Indeed they do." Dominic's smile never wavered, but something shifted in his eyes. "Though some stories are better left unread. Caspian's private affairs, for instance. The fifty-first floor serves a very specific purpose."

The casual mention made my pulse spike, but I kept my expression neutral. "I'm sure it does."

"He's protective of his privacy. Understandably so, given his position." Dominic finished his whiskey in one smooth motion. "Some secrets exist to protect people, Ms. Garcia. Not to harm them."

He stood, adjusting his cufflinks with practiced precision. "Enjoy your evening. And remember—curiosity is an admirable trait in an auditor, but discretion is what keeps auditors alive."

I watched him leave, his words echoing in my mind like a warning wrapped in silk. When I finally returned to my room an hour later, I found a book waiting outside my door.

Donna Tartt's "The Secret History." Hardcover, pristine condition, no note or explanation. I picked it up with trembling fingers and carried it inside, locking the door behind me.

The book fell open to the first page, and my breath caught. Someone had written in pencil across the title page, the letters carefully formed in handwriting I didn't recognize:

"Some secrets are meant to protect you."

The script was elegant, feminine—definitely not Caspian's bold signature I'd seen on the NDA. Someone else had access to my floor, to my room, to my private space. Someone who wanted to send a message without being identified.

I sank onto my bed, clutching the book against my chest. The building around me felt alive with hidden watchers, phantom floors, and secrets that multiplied like shadows. And somewhere above me, on floors that didn't officially exist, the real game was being played by people I couldn't see.

But now I had a new mystery to solve: who had left this book, and what were they trying to tell me?
