The reception was a business merger with champagne.

Nobody danced. They networked. Old men in Brioni suits clinked glasses with Dad while he sweated through his tuxedo, looking ten years younger now that Kaine Corp's money was legally tied to ours. Celeste was already gone. A text from her burner phone: _At airport. Thank you. I'll make it up to you._

Liar. She never did.

Damian hadn't said a word to me since the "I do." He was three conversations deep with a senator, one hand resting on the small of my back. Not possessive. Possessive would imply affection. This was marking territory. Like I was a new acquisition he hadn't audited yet.

"Mrs. Kaine," a waiter offered me a tray. "Champagne?"

I took it. I don't even like champagne. But Celeste drinks it like water. I was going to need to be very, very drunk to survive tonight.

"Celeste doesn't drink," Damian said without looking at me. He plucked the glass from my hand and set it back on the tray. "Allergic to sulfites. You told me. Three years ago."

The champagne sloshed. My heart didn't.

_Three years ago._

I forced a laugh. The one Celeste uses when she's caught in a lie - high, brittle. "God, Dame. You remember everything. I was testing you."

He finally looked at me then. Really looked. His eyes were gray, like a frozen lake. Nothing moved in them. "Were you?"

A photographer called, "Mr. and Mrs. Kaine! Kiss for the cover of Forbes!"

Damian's hand slid from my back to my jaw. He tilted my face up. His thumb brushed the corner of my mouth, and for a second I thought he was going to expose me right there. Instead, he kissed me.

It wasn't a kiss. It was a cross-examination. Clinical. Measuring. He pulled back before I could even decide if I hated it.

"Perfect," the photographer said.

The second we were alone, Damian guided me to our table. No one else sat there. Just two place settings, two water glasses, and one black coffee, steam curling up from it.

He pushed the coffee toward me. "You've been trying to quit. For the wedding. New habit?"

Celeste drank four cups before noon. Black. No sugar. She said it was the only thing that kept her awake during Dad's board meetings. I drank tea. Chamomile. Because coffee made my hands shake.

I stared at the cup. If I refused, the game was up. If I drank it, I'd be jittery and sick on my wedding night.

I picked it up.

Damian watched. Not my face. My hands.

The coffee touched my lips. Bitter. Burnt. I swallowed.

And didn't shake.

Because I'd been practicing. Every morning for a month, after Celeste got engaged, I'd choked down black coffee until my body stopped betraying me. Just in case. Just in case she ran. Just in case I had to be her.

I set the cup down. Empty. "Habit's dead," I said, using Celeste's words. "Took you three years to notice."

Something flickered in his eyes. Not surprise. Satisfaction.

He leaned across the table, close enough that I could smell his cologne. Something expensive and sharp, like cedar and cold cash. "It did," he said quietly. "Three years ago, you told me you'd quit the day you stopped loving me."

My fingers went numb.

Celeste had never been in love with Damian. She'd called him "the human spreadsheet" and slept with Marco the night of the engagement party.

So who the hell had he been talking to for three years?

Before I could answer, his phone buzzed. He glanced at it, then stood. "Stay here. I have a gift for you."

He walked off. No explanation. No kiss goodbye. Just command.

I sat there, heart hammering against my ribs, staring at the empty coffee cup. My phone buzzed in the bouquet.

Unknown number: _Good girl. You passed the first test. But Lucien was always the better actor. Don't let Damian find out why he's really dead. - A friend_

Lucien. Damian's twin. The one the news said died in a boating accident two years ago.

I looked up.

Damian was across the ballroom, watching me. He raised his own coffee cup in a mock toast.

He hadn't taken a sip of it all night.

The "gift" was a penthouse.

Fifty-seventh floor. Glass walls. A view of Manhattan that cost more than my dad's entire company used to be worth. The bedroom was already full of clothes in my size. Not Celeste's size - _my_ size. Dresses I'd liked on Instagram and never bought. A sketchbook with my initials. A copy of _The Count of Monte Cristo_ with the corners dog-eared at my favorite chapters.

I was standing in the middle of it, still in the wedding dress, when I found the safe.

Biometric. Thumbprint.

I pressed mine to it without thinking.

It opened.

Inside: a stack of cash, a passport, and a red leather diary. _Property of C. Kaine_ stamped on the cover in gold. Celeste's. I'd seen her write in it when we were kids. She stopped after Mom died. Said writing things down made them real.

The first page was dated three years ago.

_January 12th_

_I met him today. Not Dame - the other one. Lucien. He was at the Kaine Foundation gala, standing by the ice sculpture like he wanted to stab it. He doesn't look like his photos. He's thinner. Meaner. He called me Celeste and I didn't correct him. He said, "You hate these things too, don't you?" And I did. I really did._

My stomach dropped.

I flipped pages.

_February 3rd_

_Lucien kissed me behind the fundraiser tent. He tastes like whiskey and bad decisions. He thinks I'm engaged to his brother. I haven't told him. I can't. Dame looks at me like I'm a contract. Lucien looks at me like I'm a fire._

_March 19th_

_D knows. I don't know how, but he knows. He came to my apartment. Didn't yell. Just said, "You have two choices. End it, or I end him." He said it like he was discussing a stock split._

_April 1st_

_Lucien's gone. Boat accident. They said it was an accident. D told Dad it was a tragedy. He didn't even come to the funeral. He sent flowers. White roses. I hate roses. They give Elise hives._

I slammed the diary shut.

He knew. Damian knew Celeste was in love with Lucien. He knew three years ago. And he'd just told me, _"You said you'd quit the day you stopped loving me."_

But Celeste never loved him.

So who was he talking to?

A floorboard creaked behind me.

I spun, the diary clutched to my chest. Damian stood in the doorway, tie loosened, jacket off. He looked human for the first time all day. Tired.

"You found it," he said. Not a question.

"I wasn't-"

"Looking for it?" He stepped inside, shut the door. The lock clicked. "No. You were looking for her. You always are."

He knew. He knew I wasn't Celeste.

The room tilted. "Damian, I can explain-"

"Can you?" He crossed to the bar, poured two fingers of scotch. Didn't offer me one. "Explain why you've been forging her signature since you were sixteen? Explain why you took the fall for her DUI? Explain why you're wearing her dress, but you're standing in _your_ bedroom?"

Every word was a bullet. He'd counted them all.

"How long have you-"

"Known?" He drank. "Since the engagement party. You spilled red wine on your dress and didn't flinch. Celeste would have screamed. She hates merlot. You hate being embarrassed."

He set the glass down. "I proposed to her anyway."

"Why?" The word tore out of me. "If you knew she loved Lucien, if you knew I was-"

"Because she would have said no." He walked to me, slow, deliberate. Stopped a foot away. I could see the scar through his eyebrow now. It wasn't like mine. Mine was from the swing. His was surgical. Precise. "And I didn't want Celeste."

His thumb brushed my cheekbone, right under the scar. Same spot he'd touched during the kiss.

"I wanted the girl who took her punishments. The girl who memorized her coffee order. The girl who learned to drink it black, just in case."

My breath stopped.

"I wanted you, Elise."

The diary slipped from my hands.

He caught it before it hit the floor. Opened it to the last entry. One I hadn't read yet.

Dated yesterday. In handwriting I didn't recognize.

_She said yes. Finally. Get the papers ready. If Celeste runs, Elise will take her place. She always does. -D_

Yesterday. Before Celeste ran. Before I put on the dress.

He'd planned this.

The door to the penthouse slammed open.

"Hey, brother," a voice drawled from the living room. "Meet the woman who buried me."

Damian didn't even turn. "Right on time."

A man leaned against the doorframe. Same face as Damian. Same cold gray eyes. But his hair was longer. His suit was cheaper. And he had a grin that cut like a knife.

Lucien Kaine. Alive.

He looked straight at me and winked.

"You must be Elise. I've heard so much about you."

Lucien didn't wait for an invitation.

He walked into _my_ bedroom like he owned the penthouse, the air, me. He picked up the diary from the floor, flipped to yesterday's entry, and whistled. "D, your handwriting's gotten worse. You always did press too hard when you were lying."

Damian didn't move. Didn't blink. "You weren't supposed to come upstairs."

"Plans change," Lucien said. He looked at me. Really looked. Not like Damian, who catalogued. Lucien _saw_. "So you're the forger. Smaller than I expected. Meaner eyes."

"Get out," I said. My voice didn't shake. Three years of coffee training was good for something.

Lucien grinned. "She sounds like you when you're pissed, D. It's uncanny." He tossed the diary onto the bed. "I'm just here for the merger documents. The ones Daddy signed this morning. The ones that transfer Kaine Corp's controlling shares to the 'Kaine spouse' in the event of his death."

Ice slid down my spine.

Damian's expression didn't change. "You're not dead, Lucien."

"Not legally, no." Lucien pulled a folded paper from his jacket. A death certificate. _Lucien Kaine. Cause of death: accidental drowning. Date: April 2nd, three years ago._ "But you filed this. You buried me. You told the world I was gone so you could have the company to yourself. And now you've married her"-he pointed at me-"so when you _do_ die, she gets everything. Not me. Not Dad. Her."

I looked at Damian. "Is that true?"

"Yes."

No denial. No explanation. Just _yes_.

Lucien laughed, but it wasn't amused. "He's been planning this since college, sweetheart. He knew Celeste was weak. He knew you were strong. He just needed you legal. A wife can inherit without a will. A mistress can't."

"So I'm a loophole," I said.

"You're the whole damn plan," Damian said quietly. "Lucien embezzled forty million from Kaine Corp three years ago. I covered it up. I declared him dead to save the board from a scandal. In exchange, he disappeared. He was supposed to stay gone."

"Until you married the wrong twin," Lucien cut in. "Now I'm back, because if I don't get those shares, I go to prison. And if I go to prison, I'm taking you with me, brother. I kept records. Of everything."

He stepped toward me. "That includes the part where you told Celeste to break it off with me or you'd ruin her. The part where you leaked the boat accident story yourself. The part where you've been stalking Elise since she was twenty."

Damian's jaw ticked. First crack I'd seen all day.

"Stalking?" I asked.

Lucien pulled out his phone. Swiped. Turned it to me.

Photos. Hundreds. Me at college. Me at my old apartment. Me signing Celeste's name on a loan doc. Me, last week, buying this exact wedding dress _in my size_ because Celeste "lost weight."

Time-stamped. Date-stamped. Years of them.

"He had me followed," Damian said. "For your protection."

"Protection," Lucien mocked. "He has a room, Elise. At his old place. Walls covered. Schedules. Food orders. He knows you hate cilantro. He knows you cry at dog food commercials. He knows you forged Celeste's SATs so she could get into NYU."

I felt sick. Violated. _Seen_ in a way that had nothing to do with love.

"So what now?" I asked. My hands were steady. They always were when I was cornered. That's what made me good at forgery. "You two fight to the death and I get the company?"

"No," Damian said. He finally looked at Lucien. "We do what we agreed. She signs the documents."

"What documents?" I said.

Lucien smiled. "The ones that make her CEO if you die, D. And the ones that make me CEO if _she_ dies."

He pulled a knife from his jacket. Not to stab. To cut.

He sliced his thumb, then held it out to me. "Biometric safe needs fresh blood, sweetheart. Yours or his. I'm betting you don't want it to be his."

Damian didn't stop him. He just watched me.

And I understood.

This wasn't a marriage. This was a hostage exchange. Damian wanted me to control the company so Lucien couldn't. Lucien wanted me to sign so he could kill me later and take it anyway.

And Celeste? Celeste was the decoy. The only person in this room who got to run.

I looked at the knife. Then at Damian. "Three years ago. The fundraiser. You said I told you I'd quit coffee the day I stopped loving you."

"Yes."

"Celeste never loved you."

"No," he said. "But you did."

The room went silent.

"What?"

"The fundraiser," he said. "You were there. You weren't on the list. You wore the catering uniform so you could watch Celeste. You spilled wine on your apron. I helped you clean it up. You told me you were pre-med. You told me you hated your sister's life. And you told me you'd quit coffee the day you stopped loving the man who made you wear that uniform."

I remembered. God, I remembered. One night. One conversation with a stranger who had kind eyes and a scar through his eyebrow. I'd thought he was a waiter. He'd thought I was the help.

"You never told me your name," he said. "But I found out. And I've been waiting for you to stop wearing hers."

Lucien snorted. "Jesus, D. You're sicker than I thought."

Damian ignored him. "Sign the papers, Elise. Take the company. Burn it down. I don't care. I just want you to choose. Her life, or yours."

He slid a folder across the bed. _Kaine Corp Contingency Transfer_. My name already typed. _Elise Kaine_.

Not Celeste.

Lucien put the knife to his own palm. "Sign it, and I walk. Don't, and I start with him. Your choice, Mrs. Kaine."

My forger's hands didn't shake.

I picked up the pen.

And signed it _Celeste Marie Kaine_.

Perfect. Flawless. Indistinguishable from the real thing.

Damian's face went white.

Lucien started laughing. "Oh. Oh, you're _good_."

I dropped the pen. "If you wanted Elise, you should have proposed to her," I said to Damian. "But you didn't. You proposed to Celeste. So that's who you married."

I looked at Lucien. "And if you want the company, you'll have to kill the right twin. Good luck figuring out which one that is."
