Chapter 1: The Folder

POV: Calista

I was folding Lucian's shirts when the doorbell rang at 10:47 p.m. My husband was supposedly in Singapore, and the man on my porch was the last Thorne I expected to see.

Caspian stood under the porch light, soaked through. In six years of marriage, his younger brother had never once come to my door without an invitation from his mother.

"Caspian?" I pulled my cardigan tighter. "Is it your mother? Is something wrong?"

"Can I come in, Calista?"

His voice was low and level. It was the voice of a man who had already rehearsed the worst sentence he would ever say.

I stepped aside.

He stood in my living room like a guest who did not trust the chairs. His coat was plain, and his watch was the cheap steel kind sold in airport shops. The family called him the quiet one. Viv had a crueler name for him, and she used it at every dinner.

He carried a thick black folder against his chest.

"Sit down," he said.

"I'd rather stand. What is this?"

"Please. Listen until the end. Then you can hate me however you like."

I sat on the edge of the sofa because my legs had decided for me. He took the chair across from me and rested the folder on his knees.

"Lucian is having an affair," he said.

I laughed, a sharp and ugly sound. "No. You're mistaken."

"Calista."

"My husband is not that kind of man. Someone is lying to you."

"I wish that were true."

"Then who is she?" I demanded, because I needed a stranger's name. Anyone's name would do.

He was quiet for a long moment. "My wife."

The room tilted. "Viv? Your Viv?"

"Yes."

"She hugged me at my birthday dinner. Last month."

"I know." His jaw tightened. "She was wearing a dress Lucian bought her."

I stood so fast the coffee table rattled. "Get out. You're jealous of him. You've always been jealous of him. Get out of my house."

Caspian did not move, and he did not raise his voice. He opened the folder and laid the first page on the table.

"Look at it," he said. "If you still want me to leave after that, I'll go and never mention this again."

I should have thrown the folder at his face. Instead, I looked down.

It was a screenshot of a message thread between Viv and her phone's contact for Lucian. The messages were not subtle.

Lucian: I can't stop thinking about last night.

Viv: Does Caspian suspect anything?

Lucian: He's too wrapped up in his own failures to notice. And Calista is too trusting to ask questions. We're close to having everything. Just a little longer.

The last line carried my husband's phrasing. I knew it the way you know your own handwriting.

My ears began to ring. "This could be fake," I said weakly.

"It could," Caspian agreed. "So here is the next one."

He laid down a photograph of the Aurelian's marble lobby. Lucian stood at the elevators with his hand on the small of a woman's back. She wore a red coat I had watched her buy in a boutique in March. Her face was tilted toward his, and she was smiling the way she had never smiled at the man she married.

For a moment, I forgot how to breathe.

"There are more," he said quietly.

There was a photograph of Viv's hand resting on my husband's chest. She wore the bracelet I had helped her choose for her thirtieth birthday. Then came hotel records: suite 1904, booked under Lucian's name every Thursday for eleven months. Champagne. Jewelry. A weekend in Kyoto.

The Kyoto trip was the "client retreat" Lucian had attended in the spring. I had packed his suitcase for it.

I had ironed the shirts he wore to meet her.

I pressed my palm over my mouth. I would not make a sound in front of this man. I would not let him hear me break.

Caspian looked away, giving me that privacy. It was the kindest thing anyone had done for me all year.

"Eleven months," I whispered. "I slept beside him for eleven months."

"I know."

"Does your family know?"

"No. Only me." He closed the folder. "I found the first charge by accident, on a card I was never meant to check. Since then I've spent three weeks checking everything else. I audit the paperwork nobody in this family bothers to read."

"Why are you showing me this?"

"Because you deserve the truth."

"That's all?"

He hesitated. For the first time, something sharp moved behind his calm face.

"No," he said. "It isn't."

I studied him then. The cheap watch and worn coat did not match the way he sat. He did not look like the failure Viv described. He looked like a man who had been keeping his anger in a locked room for a very long time.

"Viv told me once that she married me out of pity," he said. "She said I was a mistake she'd have to learn to live with."

"Then she's a fool."

A small, surprised smile touched his mouth. "You're the first person in this family to say that out loud."

"Then your family has terrible judgment."

"I'm beginning to think so too."

Rain tapped the window. I thought of every Thursday, every late meeting, every "don't wait up." I had built that wall one brick at a time by never asking a single question.

"What do you want from me, Caspian?"

"I could expose them tomorrow. Lawyers. A scandal. A messy divorce where they cry and blame each other."

"But?"

"That's too clean." His eyes lifted to mine. "They think they're safe. They think we're blind. I want them to feel what we felt tonight."

I swallowed. "How?"

"Let them find out slowly. Let Lucian wonder where his wife goes at night. Let Viv watch another woman stand at my side."

The room felt very small.

"Caspian," I breathed. "What are you saying?"

He held my gaze, and his voice dropped to something quiet and unflinching.

"I'm saying, Calista, that you should become my lover."
