I bought the GPS tracker on Amazon. Two-day shipping. It was small enough to fit inside Beckett's car key fob if you removed the battery cover and wedged it in carefully. I did it while he was in the shower on a Sunday morning. Took me forty seconds.

The tracker synced to an app on my phone. I watched the blue dot move through Manhattan like I was monitoring a patient's EKG. Clinical. Detached. Noting patterns.

Monday: Walker Enterprises. Lunch at Le Bernardin. Back to the office. Home at seven.

Tuesday: Walker Enterprises until three. Then the blue dot stopped at The Plaza and stayed there for four hours.

Thursday: Same thing. The Plaza. Four hours.

I let it run for two weeks. The pattern never changed. Tuesday and Thursday afternoons. Always The Plaza. Always the same duration.

I had a friend in hospital security. Marcus. He owed me a favor from when I covered his overnight shift so he could see his daughter's recital. I called it in.

"I need lobby footage from The Plaza," I said. "Tuesdays and Thursdays. The past two weeks."

He didn't ask why. "When do you need it?"

"Tomorrow."

The footage came through on a thumb drive. I watched it in my office between surgeries. Door locked. Lights off.

There was Beckett, walking through the Plaza lobby at 3:47 PM on a Tuesday. Charleigh Rose beside him. Her hand in his. She was laughing at something he said. He looked at her the way he used to look at me.

They took the elevator to the eighth floor. I cross-referenced the time stamp with the hotel's booking records—Marcus had been thorough. Suite 812. Booked under a shell company called Rosemont Holdings LLC. Beckett's corporate card on file.

I watched Thursday's footage. Same lobby. Same elevator. This time Beckett carried a small blue box. Tiffany blue.

He opened it in the elevator. I watched Charleigh's face light up. Watched her throw her arms around his neck. Watched him kiss her.

I paused the video. Zoomed in on the box.

Diamond necklace. Platinum setting. I'd seen it before in a catalog Beckett left open on his desk. Harry Winston. $280,000.

I took screenshots. Saved everything to an encrypted drive. Then I pulled Beckett's credit card statements from our joint financial portal—he'd never removed my access—and cross-referenced every charge. The hotel suite. The necklace. Dinners at restaurants I'd never been to. Flowers sent to an address in Tribeca I didn't recognize.

I made a spreadsheet. Timestamps. Locations. Dollar amounts. I was good at spreadsheets.

When I finished, I sat back and looked at my work. Two weeks of evidence. Ironclad. Undeniable.

I felt nothing.

Valerie Garza's office was in Midtown. Twentieth floor. Floor-to-ceiling windows overlooking Bryant Park. She met me in the conference room with coffee I didn't drink.

I handed her the encrypted drive.

"Everything's on there," I said. "GPS logs. Hotel footage. Financial records. Cross-referenced."

She plugged the drive into her laptop. Opened the files. Her face didn't change as she scrolled through the evidence, but her pen moved faster. She was taking notes.

After ten minutes, she looked up.

"This is airtight," she said. "Adultery. Financial dissipation of marital assets. If you want a fault-based divorce, you have it."

"I want it," I said.

"He'll fight."

"Let him."

Valerie uncapped her pen. Recapped it. A small mechanical motion I'd learned meant she was thinking.

"The court filing goes public record," she said. "The Walker name carries weight in this city. His legal team will be aggressive."

"I don't care."

She studied me for a moment. Then she nodded. "I'll file tomorrow morning."

I stood up. Shook her hand. Left.

The whispers started three days later.

I heard them in the hospital cafeteria first. Two nurses from cardiology at the table behind me. They didn't know I was there.

"Did you hear about Dr. Montgomery's husband?"

"The affair?"

"Apparently the other woman feels terrible. She didn't know he was still married. He told her it was over."

"God, that's awful. Poor thing."

I kept eating my salad. Didn't turn around.

The whispers followed me through the week. At the hospital foundation gala planning meeting. At the dry cleaner. At the coffee shop near the penthouse.

Charleigh Rose was making her rounds. Playing the victim. She felt terrible. She never meant for this to happen. Beckett told her the marriage was already over. She was just as shocked as everyone else.

I listened to it all with the same detachment I'd used to watch the hotel footage. Clinical. Noting symptoms.

Manipulation. Reputation management. Strategic victimhood.

Classic.

I scheduled three surgeries for the following week. Back-to-back. Complex cases. The kind that required twelve-hour days and complete focus.

I didn't need to think about Beckett or Charleigh or the whispers. I needed to work.

My hands were steady. They were always steady.

That was the only thing that mattered.

Beckett came home at eleven.

I heard his key in the lock. Heard him drop his briefcase by the door. Heard his footsteps cross the living room.

I was sitting in the dark. Hadn't turned on any lights. I'd been there for an hour, just sitting, watching the city lights through the windows.

"Nala?"

I didn't answer.

He found me anyway. Turned on the lamp. The light made me blink.

"We need to talk," he said.

I looked at him. He was still wearing his suit from work. Tom Ford. Navy. The one I'd picked out for his birthday last year.

"My assistant heard something today," he said. "About a legal filing. My name attached to it."

I waited.

"Is there something you want to tell me?"

I pressed my thumb against the inside of my left wrist. Counted my pulse. Seventy-two beats per minute.

"No," I said.

He exhaled. Ran his hand through his hair. "You're making a scene out of nothing. Whatever you think you know—"

"I know exactly what I'm talking about."

The words came out quiet. Flat. I stood up.

Beckett stepped into my path. "Nala. Listen to me. You have no idea—"

I walked past him. Didn't touch him. Didn't look back.

The guest bedroom was at the end of the hall. I opened the door. Closed it behind me. Turned the lock.

I could hear him standing outside. Waiting. Then his footsteps retreated.

I sat on the edge of the bed and looked at my hands in the dim light from the window.

Still steady.

The Walker Foundation Gala was four days later.

I'd been on the planning committee for two years. Helped choose the venue. Approved the menu. Written the speech Eleanor would give about cardiac research funding.

I wore black. Simple. A dress I'd owned for three years. No jewelry except my wedding ring.

I arrived alone.

The Met was already full. Four hundred people in evening wear. Champagne on trays. String quartet in the corner. Marble floors polished to a mirror shine.

I saw Eleanor first. She was holding court near the main staircase. Recovered from surgery. Strong. She saw me and smiled thinly.

I didn't go over.

I took a glass of champagne from a passing tray. Didn't drink it. Just held it.

Then I saw Beckett.

He was standing near the bar with a group of Walker Enterprises board members. Laughing at something James Whitfield said. He looked relaxed. Happy.

Charleigh Rose was beside him.

She wore white. A dress that probably cost more than my car. Her hair was swept up. Her makeup was perfect.

And around her neck was the Harry Winston necklace.

I recognized it immediately. The platinum setting. The diamonds catching the light. $280,000 hanging against her collarbone in front of four hundred witnesses.

She was showing it off. Touching it with her fingertips. Tilting her head so it caught the light.

I watched her for thirty seconds. Noted the way she leaned into Beckett. The way he put his hand on her lower back.

Then I walked across the floor.

My heels clicked on the marble. The sound carried. People turned to look.

I stopped in front of Charleigh.

She looked up at me. Her eyes went wide. Startled. She touched the necklace instinctively.

"Nala," Beckett said. His voice had a warning in it.

I didn't look at him.

I looked at Charleigh. At the necklace. At the hand touching it like she was protecting something precious.

Then I lifted my champagne glass and poured it.

The Dom Pérignon hit the diamonds first. Ran down the platinum chain. Soaked into the white dress. Dripped onto the marble floor.

Charleigh gasped. Stepped back. Her hands flew up.

The room went completely silent.

I set the empty glass on a nearby table. Looked at Charleigh. My voice came out low and clear.

"Diamonds suit women who earn them," I said. "Not ones who steal them."

Charleigh's mouth opened. No sound came out.

I turned to walk away.

Beckett grabbed my arm. Hard. His fingers dug into my wrist.

"What the hell is wrong with you?" he said.

I looked down at his hand. Then up at his face.

"Let go," I said.

"You're embarrassing yourself—"

"Let. Go."

He didn't.

Charleigh made a small sound behind him. A whimper. I saw her sway. Saw her hand go to her forehead.

"Beckett," she whispered. "I don't feel—"

She collapsed.

Beckett released my arm instantly. Lunged forward. Caught her before she hit the floor.

"Charleigh!" His voice cracked. "Someone call an ambulance!"

I stood there. Watched him kneel on the marble. Watched him cradle her head. Watched her eyelids flutter.

She wasn't unconscious. I could see her breathing. See the tension in her neck.

Performance.

Beckett looked up at me. His face was white. Furious.

"Are you happy now?" he said. "Look what you did."

I looked at Charleigh in his arms. At the champagne-soaked necklace. At the four hundred people watching.

Then I looked at Beckett.

"Yes," I said.

I walked out.

Behind me, I heard Eleanor's voice. Sharp. Commanding. "Someone help her up. And someone find Dr. Montgomery—"

I kept walking.

My hands were steady.

They were always steady.
