"You forgot to put on Vivian’s signature ring."

The voice didn’t emerge from the predatory shadows of the library, but from the cool, clinical vacuum of the hallway. I gasped, my hand flying to my bare throat as my back hit the cold wainscoting.

Standing there was Marcus Langley. He wasn’t just the head of security; he was Lucian’s shadow—the executive assistant who managed the billionaire’s life with the harrowing precision of a Swiss watch. He stood with a leather-bound planner in one hand and an iPad in the other, the glow of the screen reflecting off his thin, silver-rimmed glasses.

His eyes weren't on my face. They were locked onto my right hand—the hand that was currently trembling and devoid of the five-carat canary diamond Vivian Lancaster never went a day without.

My breath hitched. I tried to curl my fingers into a fist, tucking the evidence of my fraud into the folds of my silk skirt, but the damage was done. The hallway, which had felt like a refuge seconds ago, suddenly felt like a kill-box.

"I… I must have left it by the sink when I was freshening up," I managed, my voice cracking. The breathy, Mid-Atlantic lilt of 'Vivian' slipped for a terrifying second, revealing the raw nerves of Celeste Harper.

Marcus stepped closer, the overhead chandelier masking his expression behind a wall of glare. "Vivian Lancaster wouldn't leave that ring by a sink. She would have sooner left her own hand behind. It was a gift from Lucian’s father. It was her only real leverage in this family."

He stopped a few feet away, his gaze finally traveling up to meet mine. He didn't look angry. He looked exhausted, like a man who had been watching the same tragic play on repeat for years.

"Who are you?" he asked. It wasn't a shout. It was a tired, bureaucratic inquiry.

"Marcus, I don't know what you're talking about," I said, trying to regain my footing, forcing the aristocratic arrogance back into my spine. I tilted my chin up, the way Vivian did in her Instagram stories. "I’m exhausted, and Lucian is being… impossible. If you’ll excuse me—"

"You’re the fourth one this month," he interrupted, his voice flat.

I stopped mid-step, the air leaving my lungs. "The fourth what?"

"The fourth 'solution' Emelia has tried to drop into that room," Marcus said, scrolling through his tablet with a detached flick of his thumb. "The first three were world-class psychiatric nurses. One lasted four hours. The second lasted two. The third didn't even make it past the threshold before Lucian hurled a crystal decanter at her skull. He’s volatile, Celeste. Or whatever your name actually is."

The sound of my real name—or at least the acknowledgment that I wasn't her—felt like a bucket of ice water. I looked frantically down the corridor, terrified that a maid or, worse, Lucian himself, might be listening.

"How long have you known?" I whispered, my shoulders finally sagging. The mask was heavy, and for a moment, I just wanted to let it shatter.

"Since you stepped out of the black sedan," Marcus said. "Vivian walks with her weight on her toes, like she’s constantly ready to flee a boring conversation. You walk with your weight on your heels—the walk of someone who is carrying a casket on her back. Also, you have a soul in your eyes. Vivian’s were as empty as a foreclosed penthouse."

I let out a shaky breath, leaning against a marble pedestal holding a bust of some long-dead Aldridge ancestor. "Are you going to tell him? Are you going to call the police?"

Marcus looked toward the library door. Inside, the muffled sound of glass shattering echoed through the wood. A look of genuine pity crossed his face—not for me, but for the man trapped in the dark.

"Lucian is a beast because he’s starving," Marcus said softly. "He’s starving for something real, and all he gets are ghosts and expensive lies. If I tell him the truth, he’ll descend into a darkness he’ll never return from. And frankly? I need this paycheck to keep my own family in Greenwich. Emelia pays a premium for silence."

He stepped forward and handed me a folded slip of heavy cream stationery.

"What is this?"

"A survival guide," Marcus replied. "A list of Lucian’s triggers. He hates the smell of lilies—it reminds him of the ICU after the crash. He hates whispering; he thinks everyone is plotting a coup. He hates the taste of peppermint. And most importantly, do not touch the scarred skin on his temples. If you do, he will snap."

I looked down at the list. It was a map of a broken man’s psyche. "Why are you helping me?"

"Because you’re the first one who didn't run out of that room screaming," Marcus said, his eyes narrowing. "You stood your ground. You talked back to him. For a second, I actually heard his heart rate stabilize on the monitor. If you can keep this up, maybe he’ll finally agree to the surgery. Maybe he’ll become a human being again."

"And if I fail?"

Marcus leaned in, his voice dropping to a whisper that chilled me to the bone. "If you fail, Emelia will erase you. She didn't hire you to be a friend, Celeste. She hired you to be a tool. If the tool breaks, she discards it. And she’s very good at making sure the trash is never found."

He checked his Patek Philippe. "Lunch is served in ten minutes. Vivian likes her kale salad with the dressing on the side and a glass of chilled Sancerre. Don't forget the ring. It’s in the floor safe in your dressing room. Code is 0-9-1-2. His birthday."

Marcus turned and walked away, his footsteps silent on the plush Persian carpet, leaving me alone with a list of triggers and the crushing weight of my new reality.

I found the safe. 0-9-1-2. The door clicked open, and there it sat. The yellow diamond was so large it looked gaudy, a heavy symbol of a love that had turned into a blood-feud. I slid it onto my finger. It felt like a shackle.

As I walked back toward the dining room, I passed a window overlooking the sprawling, mist-covered Westchester grounds. In the distance, near the iron gates, I saw a black SUV idling. I recognized the plates.

Someone was watching the estate. Someone who wasn't working for Emelia.

I shook off the paranoia and entered the dining room. Lucian was already there, seated at the head of a mahogany table that could seat forty. He looked different in the gray light—less like a monster and more like a man who was simply… adrift. He was in a fresh charcoal shirt, but his hair was a chaotic mess, and his sightless eyes were fixed on the window.

"Sit," he commanded, his voice a low vibration. "I can hear your heart rate from here, Vivian. It’s erratic. It’s annoying."

"It’s called being alive, Lu," I said, sliding into the chair to his right, making sure my silk sleeves rustled just enough for his ears to track me. "You should try it sometime. It beats being a gargoyle."

The maid placed the salad in front of me. I looked at the dressing on the side and felt a surge of gratitude for Marcus.

"I heard you talking in the hall," Lucian said suddenly.

My fork stopped halfway to my mouth. My pulse spiked. "I was just checking the afternoon schedule with Marcus."

"Marcus is a drone," Lucian spat. "But you… you sound different when you think I’m not listening. Your voice loses that… plastic, Upper East Side coating. Why?"

I swallowed hard, my mind racing through Vivian’s journals. I needed a lie that tasted like the truth.

"Maybe because being back here makes me realize how much of a performance Paris was," I said, my voice dropping the lilt just a fraction. "Everyone there wanted a piece of the Aldridge brand. You… you just want to hate me. It’s honest. It’s refreshing."

Lucian turned his head toward me, his brow furrowing. He reached out, his hand hovering over the table, searching. Instinctively, I moved my hand toward his.

His fingers brushed against mine, and then they stopped. He didn't grab my wrist this time. Instead, his fingers slid over the back of my hand, tracing the shape of the ring. He felt the cold platinum, the sharp, multi-carat edges of the diamond.

A strange expression crossed his face—a mixture of relief and something that looked like profound, jagged disappointment.

"The ring," he whispered. "You’re wearing it."

"I told you. I’m not leaving," I replied, my voice steady.

He pulled his hand back as if the diamond had burned him. He stood up, knocking his heavy chair back, his face twisting into a mask of sudden, inexplicable agony.

"Get out," he rasped.

"Lucian? What did I do?"

"You’re wearing the ring!" he shouted, his voice cracking with a raw, bleeding emotion that paralyzed me. "The real Vivian Lancaster sold that ring to a jeweler in Zurich four months ago to pay off her baccarat debts! I know, because I’m the one who bought it back through an anonymous broker!"

My heart stopped. The world tilted on its axis.

He moved toward me, catching the edge of the table to stabilize himself. His face was inches from mine, his clouded eyes burning with a terrifying, focused clarity.

"So I’ll ask you one more time," he hissed, his hand catching my jaw, his thumb pressing hard against my skin. "Who the hell are you, and what have you done with my fiancée?"
