Marcus Webb's office was on the fourth floor of a building in Midtown that looked like it had been nice once. The elevator groaned. The hallway smelled like old coffee and carpet cleaner.

I knocked on the frosted glass door at nine a.m. exactly.

Webb opened it himself. He was maybe fifty. Tired eyes. Good suit. He gestured me in without small talk.

"Katherine Larson?"

"Yes."

"Daniel said you'd be punctual."

I sat in the chair across from his desk. He sat down and folded his hands.

"What can I do for you?"

I pulled my leather notebook from my bag and set it on the desk between us. I opened it to the first marked page.

"My husband has been making recurring payments to an address in Brooklyn. Twice a month for two years. The address is our old apartment. He told me we sold it three years ago to cover the down payment on our current place."

Webb picked up the notebook. He scanned the columns.

"You documented all of this yourself?"

"Yes."

He flipped a page. Then another.

"Venmo trails. Credit card charges. Cross-referenced dates." He looked up at me. "Most clients come in with suspicions. You came in with a roadmap."

"I worked two jobs once," I said quietly. "I'm good with numbers."

He set the notebook down and leaned back in his chair.

"What do you think is happening?"

"I think my husband maintained ownership of the apartment. I think someone is living there. I think he's been using our money to pay for it."

"You've been to the address?"

"On Christmas Eve."

"And?"

"A woman answered the door. She was wearing a Tiffany necklace I saw on our credit card statement in November. There was a child. A boy. Maybe two years old."

Webb picked up a pen. He didn't write anything. He just held it.

"The child looked like your husband?"

"Yes."

He nodded once. Slow.

"I can get you property records. Bank transfers if they exist. Photos if needed. It'll take seventy-two hours for the first layer. More if you want audio or deeper financial work."

"I want everything," I said.

He looked at me for a long moment.

"This won't be easy to see."

"I've already seen it," I said. "I just need proof."

He took the case.

Three days later, Webb called.

I met him at a coffee shop two blocks from his office. He handed me a manila folder across the table.

"Property records," he said. "The Brooklyn apartment. Purchased eight months ago. Down payment: forty-seven thousand dollars, withdrawn from a joint savings account in your and your husband's names. Title registered solely to Teresa Perez."

I opened the folder. The deed was on top. I saw Gavin's signature on the withdrawal authorization. I saw Teresa's name on the title line.

Forty-seven thousand dollars.

I flipped to the next page. A photocopy of the bank statement. The date was March 14th. I remembered that day. Gavin had told me he was moving funds into a higher-yield account. I'd said that sounded smart.

I closed the folder.

"Thank you."

Webb slid a second folder across the table.

"This one's harder," he said.

I opened it.

Bank transfer records. Twelve months of systematic withdrawals from my trust fund into an account I didn't recognize. Five thousand here. Eight thousand there. Smaller amounts—fifteen hundred, two thousand—spaced irregularly enough that I'd never noticed a pattern.

Ninety-three thousand dollars total.

I turned the page.

Itemized charges linked to the secondary account. Furniture deliveries to the Brooklyn address. Grocery orders. Car insurance payments for a vehicle registered to Teresa Perez. The Tiffany purchase in November—necklace and earrings, fifty-two hundred dollars.

I stared at the line items.

My inheritance. Spent in someone else's apartment. On someone else's life.

I turned another page.

A baby store receipt. Crib, stroller, changing table. Sixty-two hundred dollars. Date: fourteen months ago.

I closed the folder and set it on top of the first one.

Webb was watching me.

"You okay?"

"Yes."

"Most people aren't this calm."

I looked at him.

"I'm not calm," I said quietly. "I'm just not surprised."

He nodded.

"There's more if you want it. I can get communications. Emails, texts if he's careless. It'll take another week."

"Do it."

He wrote something on a notepad and slid it across the table.

"That's my direct line. Call me if anything changes. If he gets suspicious. If you need to move faster."

I folded the paper and put it in my bag.

"Thank you, Mr. Webb."

"Marcus."

I stood. He stood.

"One more thing," he said.

I waited.

"Whatever you're planning, make sure you have a lawyer present before you do anything public. People get messy when money's involved."

"I have a lawyer."

"Good."

I walked back to my car with both folders under my arm.

When I got home, Gavin's shoes were by the door. His jacket was on the chair. He was in the bedroom on a call.

I sat at the kitchen table and opened my leather notebook.

I wrote the new figures in clean columns.

Property: $47,000. Trust fund: $93,000. Tiffany set: $5,200. Baby furniture: $6,200.

I added them up.

Then I turned to a fresh page and wrote the date at the top.

December 29th.

I underlined it twice.

Then I closed the notebook and went to pour myself a glass of wine.

Marcus called on January 2nd.

I was sitting at the kitchen counter when my phone buzzed. Gavin was at work. The apartment was quiet.

"I have something," Marcus said. "You need to hear it in person."

I met him at the same coffee shop. He didn't waste time. He set a small digital recorder on the table between us.

"Audio," he said. "Recorded in the Brooklyn apartment three days ago. Teresa left her phone on the kitchen counter. Unlocked. My associate was able to access the voice memo app remotely."

He pressed play.

Gavin's voice came through clear. Relaxed. The way he sounded when he thought no one important was listening.

"—we just need to time it right. Once the kid's older, maybe three or four, I pitch it as an adoption. She can't have kids. She'll say yes."

Teresa's voice. Amused. "And if she doesn't?"

"She will. I'll make her feel like it's her idea. Like she's doing something good."

"What about the money?"

"Her trust fund's got another hundred and twenty thousand. Maybe more. I'll move it in chunks. Reinvestment, portfolio adjustments, whatever. She doesn't check."

"And then?"

"Then I file. No-fault. I'll have the lawyer draw it up so it looks like a clean split, but the marital assets are already protected under corporate structures she doesn't understand. She walks away with nothing."

Teresa laughed. It was a light sound. Easy.

"When do we move into the good place?"

"Soon," Gavin said. "Maybe spring. Once the paperwork's filed and she's out, you can move in the next day if you want."

"I want the master bedroom."

"You'll get it."

The recording ended.

I sat there looking at the recorder.

Marcus didn't say anything. He just waited.

"Is this admissible?" I asked.

My voice was steady. Calm.

"In court? Probably not. But you're not going to court. Are you."

I picked up the recorder. It was small. Lighter than I expected.

"Can you send me the file?"

"Already in your email. Encrypted. Password's the last four digits of your phone number."

I put the recorder back on the table.

"Thank you."

He slid an invoice across the table.

"That's the final bill. Expenses, hours, the works. Pay it whenever."

I looked at the total. Forty-two hundred dollars. I thought about the Tiffany set. About the crib and the stroller and the down payment on an apartment I thought we'd sold.

I thought about my trust fund.

"I'll pay it today," I said.

He nodded.

"Good luck, Katherine."

I drove home. I didn't go upstairs. I sat in my car in the parking garage and opened my email on my phone. I found the encrypted file. I entered the password.

I plugged in my headphones and played it again.

I listened all the way through.

When it ended, I sat there staring at the steering wheel.

Eleven minutes passed.

Then I got out of the car and went upstairs.

I called my father.

"I need you to come over tonight," I said. "And bring Cruz and Bennett."

"What's wrong?"

"I'll explain when you get here. Seven o'clock."

"I'll be there."

I hung up.

I called Daniel next.

"I need you here tomorrow morning. Eight a.m."

"What happened?"

"I got the recording."

There was a pause.

"I'll be there," he said.

I made coffee. I sat at the dining table and opened my leather notebook. I wrote the date at the top of a fresh page. January 2nd.

Then I wrote three names.

Family group chat. Gavin's company Slack. Daniel.

I underlined each one.

At seven, my father knocked.

I let him in. Cruz and Bennett came in behind him. They didn't ask questions. They just took off their coats and sat down at the table.

I poured coffee for everyone. I set my laptop in the center of the table and opened the audio file.

"I'm going to play you something," I said. "Don't interrupt. Just listen."

I pressed play.

Gavin's voice filled the room.

I watched their faces.

My father set his coffee cup down halfway through. He didn't pick it up again.

Cruz stood and walked to the window. He stood there with his hands in his pockets, staring out at nothing.

Bennett had been typing on his laptop. His hands stopped moving.

When the recording ended, nobody spoke.

The silence stretched. It wasn't uncomfortable. It was the kind of silence that comes right before something breaks.

My father spoke first.

"Daniel needs to hear this."

"He's coming tomorrow at eight."

My father nodded.

Cruz turned around from the window.

"What do you want to do?"

I looked at him. Then at Bennett. Then at my father.

"I'm going to send everything," I said. "The property records. The bank statements. The recordings. All of it. To the family group chat and to Gavin's company Slack. At the same time."

Bennett looked up.

"That's nuclear."

"Yes."

"He'll retaliate."

"I know."

My father leaned forward.

"Katherine."

I looked at him.

"I'm sure," I said.

He studied my face. Then he nodded once.

"Then we do it right. Daniel reviews everything first. We make sure it's clean. No room for him to twist it."

"Agreed."

Bennett pulled his laptop closer.

"I'll set up the Slack delivery. Anonymous account. I can route it so it can't be traced back to you directly."

"No," I said.

He looked up.

"I want my name on it."

Cruz smiled. It was small and sharp.

"Good."

We sat there for another hour. We didn't talk much. Bennett typed. My father made phone calls. Cruz stood by the window and didn't move.

I sat at the table with my notebook open and wrote down the sequence. Step by step. What would go where. When.

At nine, they left.

My father was the last one out. He stopped at the door and turned back.

"You okay?"

"Yes."

He looked at me for a long moment.

"Your mother would be proud," he said quietly.

Then he left.

I locked the door behind him. I walked back to the table and looked at my notebook.

Everything was ready.

I closed the notebook and went to bed.

Gavin came home at eleven. I heard him in the kitchen. Heard him open the fridge. Heard him pour a drink.

I lay on my side of the bed and stared at the ceiling.

I didn't sleep.
