The CEO's Biggest Mistake

The elevator smelled like expensive cologne and corporate ambition.

I recognized both.

I used to wear that ambition like a second skin, back when I was twenty-three, fresh out of college, convinced that hard work and loyalty were enough to build a life on. Back when I believed in things like trust. Like love. Like Ethan Kane.

That was three years ago.

A lot can change in three years.

The elevator doors slid open on the 40th floor of Kane Industries Tower, and the first thing I noticed was the silence. Then the stares. One by one, heads lifted from computer screens, fingers froze over keyboards, and the entire open-plan office seemed to collectively hold its breath.

I didn't blame them. I was worth staring at.

I smoothed the lapel of my ivory blazer, tailored, sharp, the kind that said I didn't come here to be liked, and stepped out onto the polished marble floor. My heels clicked with every step. Measured. Deliberate. The sound of a woman who had rebuilt herself from nothing and was no longer in a hurry to prove it.

"Miss Sinclair?"

The receptionist, young, wide-eyed, a little flustered, stood up so fast her chair rolled back and hit the desk behind her.

"Yes," I said simply.

"I, welcome. We've been expecting you." She grabbed her tablet, nearly dropped it, caught it. "I'm Lily, Mr. Kane's, I mean, the executive floor receptionist. I'll let Mr. Kane know you've arrived."

I tilted my head slightly. "Tell Mr. Kane I'm settling in first. I'll come to him when I'm ready."

Lily blinked. Twice. Like the sentence didn't compute.

I gave her a small, polite smile, the kind that leaves no room for argument, and turned toward the corner office that had been assigned to me. The one with the floor-to-ceiling windows overlooking the Manhattan skyline. The one the board had given me over the objections of a man who had never once, in his entire life, been overruled.

Until now.

My office was exactly as I had requested.

Minimalist. Clean. A wide glass desk, a white orchid in the corner, and a view that made you feel like you were standing on top of the world. I set my bag down, walked to the window, and looked out at the city below.

Three years ago, I had looked at this same skyline from a much lower floor. I had been nobody then, just a sharp girl from Brooklyn with a scholarship degree and a hunger that the wealthy people in this building wouldn't understand if they tried. I had clawed my way up to personal assistant to the CEO, telling myself it was just the beginning.

I had been right. It was just the beginning.

But not in the way I imagined.

I closed my eyes for a moment. Just one. Then I opened them, straightened my spine, and turned away from the window.

Sentiment was a luxury I couldn't afford today.

I had been in my office exactly eleven minutes when the door opened without a knock.

I didn't turn around. I already knew who it was. I could feel it, that particular shift in the air, like a drop in temperature, like the moment before a storm.

"You have a lot of nerve."

His voice.

Three years and it still did something inconvenient to my pulse. Low. Controlled. The kind of voice that was used to being obeyed without repetition.

I took my time turning around.

Ethan Kane stood in the doorway of my office looking exactly like the universe's cruelest joke. Tall, broad-shouldered, dressed in a charcoal suit that probably cost more than most people's rent. His jaw was sharper than I remembered. There were faint shadows under his grey eyes, the eyes that had once looked at me like I was something worth keeping.

He wasn't looking at me like that now.

He was looking at me like a problem he intended to solve.

"Mr. Kane." I clasped my hands in front of me, my voice perfectly even. "I don't recall scheduling a meeting."

Something flickered in his eyes. Gone before I could name it.

"You don't belong here," he said.

"The board disagrees." I walked to my desk and sat down, smoothly, like the conversation was already boring me. "I was hired as VP of Marketing by a majority vote. All the paperwork is in order. I believe your legal team reviewed it yesterday." I opened my laptop. "Was there something specific you needed, or did you come up here just to welcome me back?"

The muscle in his jaw tightened.

Good.

"I don't know what game you're playing, Aria,"

"Miss Sinclair," I corrected, looking up at him. Calm. Unbothered. "We're colleagues now, Mr. Kane. Let's keep things professional."

The silence that followed was the loudest thing I had heard in years.

Ethan Kane stared at me like he was seeing me for the first time and hating everything he saw, not because it was unpleasant, but because it wasn't what he expected. He had expected the girl he left behind. Soft. Hurt. Easy to dismiss.

That girl was gone.

I had buried her myself.

"This isn't over," he said quietly.

"It never started," I replied. "Close the door on your way out, please."

For a long moment he didn't move. His grey eyes searched my face for something, a crack, a flinch, any trace of the woman who had once cried herself to sleep over him.

He found nothing.

Because I had practiced this. I had stood in front of mirrors in my apartment for months, learning how to look at the idea of him and feel nothing. Or at least, look like I felt nothing. The difference, I had learned, was everything.

He left.

The door clicked shut behind him.

I exhaled slowly, turned back to my laptop screen, and allowed myself exactly five seconds of weakness, my hands flat on the desk, my eyes closed, my heart beating slightly too fast.

Five.

Four.

Three.

Two.

One.

I opened my eyes.

I had a company to dismantle from the inside. A reputation to build. A truth to uncover.

And Ethan Kane was going to help me do all of it, whether he liked it or not.

I reached for my coffee, took a slow sip, and smiled for the first time all morning.

Revenge, I thought, looks really good on me.

I don't lose.

It's not arrogance. It's simply a fact, the same way gravity is a fact, the same way Kane Industries being the most powerful corporation on the East Coast is a fact. Some things simply are, and I am a man who wins.

Always.

So why was I standing in my office, loosening my tie like the room had suddenly run out of air?

I turned away from the window and poured two fingers of whiskey from the decanter on my shelf. Didn't drink it. Just held the glass, stared into it, and tried to locate the part of myself that had walked into that office upstairs expecting to find a ghost, and instead found something far more dangerous.

Aria Sinclair.

No. She had corrected me.

Miss Sinclair.

I set the glass down harder than I intended.

Marcus was already in my office when I turned around. My CFO, my oldest friend, and the only man on earth I permitted to enter without knocking. He was leaning against the edge of my desk with his arms folded and the expression he reserved specifically for situations he found entertaining at my expense.

"I heard it went well," he said.

"Who told you that?"

"Lily. Also the three associates on the 40th floor who watched you walk out of the new VP's office looking like you'd seen a ghost." He tilted his head. "Had you? Seen a ghost?"

"She's not a ghost." I moved to my chair and sat down. "She's a problem."

"She's the best marketing strategist the board has hired in six years. Her campaign for Voss & Reid increased their revenue by 40% in under a year." Marcus paused. "You did read her portfolio before you decided to hate her, right?"

I didn't answer.

He already knew the answer.

"Ethan." His voice shifted, quieter now. The voice he used when he stopped being amused and started being serious. "It's been three years. Whatever happened between you two,"

"Nothing happened."

The lie came automatically. Smoothly. The way all my lies did, dressed up so well they almost fooled even me.

Marcus looked at me for a long moment. "Right," he said finally. "Nothing happened. That's why you've had her photo"

"Marcus."

He stopped.

I held his gaze until he uncrossed his arms and straightened up.

"She's an employee," I said. "I want her performance monitored. Every campaign, every decision, every meeting she takes. I want reports."

"You want me to spy on the VP of Marketing."

"I want due diligence on a new executive."

He stared at me. Then he sighed, the long, suffering sigh of a man who had been watching me make bad decisions for twenty years and had accepted it as his cross to bear.

"Fine," he said. "But Ethan, just talk to her."

"Get out, Marcus."

He got out.

I didn't look at the photo.

I want to be clear about that. I am not the kind of man who keeps photographs. Sentiment is weakness, and weakness is something I was taught to cut out of myself before I was old enough to understand what the word meant. My father had been very thorough about that particular lesson.

So I didn't look at the photo.

I just happened to open the bottom left drawer of my desk to retrieve a contract, and it happened to be there, small, slightly worn at the edges, face down the way I'd placed it the night I decided looking at it was doing me no good.

I closed the drawer.

Opened it again.

Took the photo out.

She was laughing in it, the kind of laugh that takes over your whole face, unguarded and real, the kind she only ever did when she thought no one important was watching. It had been taken at the Kane Industries rooftop garden, three summers ago, at the staff anniversary event. She hadn't known I was the one who took it. She'd been talking to one of the interns about something, gesturing with her hands the way she always did when she was excited, her hair loose around her shoulders.

I had looked at her across that rooftop and felt something I had no language for.

I had still let her go.

My jaw tightened.

I placed the photo face down again, closed the drawer, and picked up the contract I'd originally reached for.

Business. That's all this was. A complication to be managed.

Aria Sinclair was back, and she clearly had an agenda. The calculated entrance, the deliberate coolness, the way she had looked at me, or rather, the way she had not looked at me, like I was simply a minor inconvenience in an otherwise well-structured day.

That bothered me more than I would admit to anyone.

The Aria I remembered had never been able to hide what she felt. She was an open book, warm, honest, occasionally too trusting for her own good. That was what I had,

I stopped the thought before it finished forming.

The woman upstairs was not that Aria. She had walked into my building like she was the one who built it. She had sat behind that desk like she'd been sitting there for years. She had dismissed me, dismissed me, with a politeness so sharp it left marks.

What had happened to her in three years?

What had I done to her?

Stop.

I pressed two fingers to the bridge of my nose.

I needed to focus. The Harrington acquisition was closing next week. The board was already nervous about the new VP appointment, particularly because they hadn't consulted me before making it, a slight I intended to address at the next meeting. There were seventeen things on my agenda that required my attention before noon.

Aria Sinclair was not on the agenda.

My intercom buzzed.

"Mr. Kane." Lily's voice, tentative as always. "Miss Sinclair has requested access to the Q3 marketing data and the client portfolio files."

My hand stilled on the desk.

"She's been here three hours," I said.

"Yes, sir. She also asked me to remind you, and I'm quoting directly here, that the board granted her full executive access, and any delays in data sharing will be logged as obstruction and reported at the next quarterly review."

The silence in my office was absolute.

Three hours.

She had been here three hours and she was already using board protocol against me.

I leaned back in my chair, and despite everything, despite the whiskey I hadn't touched and the photo I shouldn't have looked at and the unfinished sentence I refused to let myself finish, I felt something unexpected move through my chest.

Something that felt dangerously close to admiration.

"Send her the files," I said.

"Yes, sir. Also, she sent this." A pause. "It's a coffee. From the 40th floor kitchen. She said, and again I'm quoting, 'He looked tense. Colleagues look out for each other.'"

I stared at the intercom.

A coffee.

She had sent me a coffee.

I didn't know if it was an olive branch or a chess move, and that uncertainty, that rare, unfamiliar uncertainty, was more unsettling than anything else she had done today.

"Leave it outside," I said.

I waited until Lily's footsteps faded. Then I got up, opened my office door, picked up the coffee, and went back inside.

I told myself it was just coffee.

I almost believed it.

That night, long after the building emptied and the Manhattan skyline turned to a scatter of lights, I stood at my window with my jacket off and my sleeves rolled up and the unanswered question sitting in my chest like something I couldn't dislodge.

Why did you come back, Aria?

And underneath that, quieter, the one I refused to say out loud:

Is it too late to make it right?

I didn't have answers.

But tomorrow, I decided, I would find them.

One way or another.

END OF CHAPTER 2

The files arrived at 4:47 PM.

I know because I was watching. Not obviously. Not desperately. I simply had my email open in one corner of my screen while I reviewed the brand positioning deck in the other, and when the notification came through I allowed myself one small, satisfied breath.

He sent them.

I had half expected him to make me wait. To drag it out for a day or two just to remind me who held the power in this building. That would have been the old Ethan. Petty in the way that only very powerful men can afford to be, using small delays and closed doors to remind you of your place.

But he had sent the files within the hour.

Interesting.

I opened the Q3 marketing folder and got to work.

Numbers have always made sense to me in a way that people sometimes don't. They don't lie. They don't say one thing and mean another. They don't stand in your office doorway with grey eyes and a jaw like carved stone and make your pulse do things it has no business doing.

Numbers are honest.

Which is exactly why what I found at 6:23 PM made me sit very still for a very long time.

I scrolled back through the data. Checked it again. Then opened the client portfolio files and cross referenced the figures against the Q3 revenue reports.

The numbers didn't match.

Not by a small margin. Not by the kind of gap that could be explained by rounding errors or currency conversion. I was looking at a $4.2 million discrepancy between what the marketing division had reportedly spent on the Harrington account and what had actually been invoiced to the client.

Four point two million dollars. Missing. Or rather, not missing. Redirected.

I followed the trail carefully, the way my mentor Sandra had taught me years ago. Numbers always leave footprints, Aria. You just have to know where to look. The money had moved through three internal accounts before landing in a discretionary fund labeled simply as "Executive Operational Reserve."

I had worked in enough corporations to know that "Executive Operational Reserve" was the kind of label that meant either something completely legitimate or something that would make headlines.

I leaned back in my chair and looked at the ceiling.

This was bigger than I expected. And I had expected quite a lot.

The question now was not what had happened to the money. I was fairly certain I could answer that with another few hours of digging. The question was who knew about it and how high up it went.

I thought about Ethan standing in my doorway this morning. The tightness in his jaw. The way he'd said you don't belong here like he was trying to convince himself as much as me.

Did he know?

Was this why he had been so desperate to get rid of me before I even sat down?

I pressed my fingers together and stared at the screen.

Three years ago I had lost everything because I trusted the wrong person at the wrong time. I had spent every day since building myself into someone who didn't make that mistake twice. I had come back to Kane Industries with a plan, a timeline, and a clear objective.

Finding a $4.2 million discrepancy on my first day was not part of that plan.

But I had learned long ago that the best opportunities were the ones you didn't see coming.

I saved copies of everything to my personal encrypted drive. Then I closed the files, shut my laptop, and sat in the quiet of my office while the city hummed forty floors below.

I needed more information before I moved. I needed to know who touched that account, who authorized the transfers, and whether the trail went up or sideways. I needed to be careful. Smart. Patient.

Patience had never come naturally to me. But betrayal had been an excellent teacher.

It was nearly eight o'clock when I finally packed up to leave.

The 40th floor was empty by then, the open office dark except for the ambient glow of the city through the windows. I liked it like this. The quiet. The feeling of a building stripped of its performance, just steel and glass and the hum of ventilation systems keeping everything breathing.

I was waiting for the elevator when I heard footsteps behind me.

I turned around.

Ethan was walking toward me from the direction of the stairwell, jacket off, tie loosened, sleeves rolled to the elbows. He looked less like a CEO and more like a man who had been working since dawn and refused to acknowledge it. There was a tiredness around his eyes that he was doing a poor job of hiding.

He stopped when he saw me. A flicker of something crossed his face. Gone before I could name it.

"Still here?" he said.

"I could say the same to you." I turned back to face the elevator doors.

He came to stand beside me. Not close. A professional distance. But in the silence of the empty floor, even a professional distance felt like something else.

"The files," he said after a moment. "Were they sufficient?"

"For now." I kept my voice neutral. "I'll have more requests next week."

"Of course you will."

There was no hostility in it this time. Just a kind of tired resignation that was somehow worse. I kept my eyes on the elevator display above the doors and said nothing.

The elevator arrived. We both stepped in.

The doors closed.

Fourteen floors to the lobby. I counted them in my head. It was something I did in uncomfortable situations. Numbers again. Reliable. Steady.

Ethan stood to my left, facing forward, his reflection ghosted in the polished metal doors. I looked at his reflection instead of him because it felt safer. Less real. The reflected version of him looked as tired as the real one, and something about that pulled at a thread inside me that I immediately tucked back in.

"You sent me coffee," he said.

"Colleagues look out for each other."

"You're not here to be my colleague, Aria."

I looked at his reflection. "Miss Sinclair."

His jaw tightened. "Miss Sinclair." He said it slowly, like the words had a taste he was still figuring out. "Why are you really here?"

The elevator reached the lobby. The doors opened.

I picked up my bag, stepped out, and paused just long enough to look back at him over my shoulder.

"Get some rest, Mr. Kane," I said. "You're going to need it."

I walked out into the Manhattan night without looking back.

But I felt his eyes on me all the way to the door.

And I did not let myself smile until I was outside.

Later, in my apartment, with a glass of water and the encrypted drive open on my personal laptop, I stared at those numbers again.

Four point two million dollars.

One day in, and I already had more than I came for.

I thought about Ethan's face in the elevator. The tiredness. The question he'd asked like it actually mattered to him.

Why are you really here?

I closed the laptop.

"Patience," I whispered to myself, in the dark, in the quiet.

The truth would come. It always did.

And when it did, nothing in Kane Industries would ever be the same.
