My sister kept walking around my husband in just a towel and called it a "test"—then one day, he did something that made her turn bright red.

I didn't move.

My hand was still on the wall where I'd stopped walking, and I stood there listening through the gap in Kayla's door like I was seventeen years old again and the world had just shifted two inches to the left.

"I can't talk right now," Kayla was saying.

Her voice was low and tight.

"Things went sideways this morning.

Andrew knows something's off."

A pause.

"No, he doesn't know about you.

He just — he recorded me, okay?

On his phone.

I panicked."

Another pause, longer this time.

"I told you this wasn't going to work.

I told you from the beginning."

I pressed my back against the hallway wall.

Andrew's brother.

His name was Daniel.

He was three years younger than Andrew, lived forty minutes away, and came to our house for dinner maybe four times a year.

He was charming in the way that people who know they're charming always are — easy laugh, quick with a compliment, the kind of man who remembered your drink order and made you feel briefly like the most interesting person in the room.

I had always liked Daniel.

Standing in that hallway, I understood that I had been very stupid.

I walked back downstairs before Kayla could open the door.

Andrew was still in the kitchen.

He'd refilled his coffee and was leaning against the counter with his arms crossed, looking at nothing in particular.

"She's on the phone," I said.

"I know."

I looked at him.

"Did you hear who she's talking to?"

He met my eyes.

"No.

Why?"

I sat down at the kitchen table.

My hands were flat on the surface.

I looked at them for a moment before I looked back up at him.

"She said Daniel's name."

Andrew didn't move.

Not even a breath.

"Say that again."

"She was on the phone.

I heard her say Daniel's name.

She said things went sideways this morning.

She said he doesn't know about you." I kept my voice even.

"Andrew.

How long has your brother been in contact with my sister?"

He set his coffee mug down on the counter.

The sound was very quiet.

"I don't know."

"But you're not surprised."

He looked at me for a long moment.

"I didn't say that."

"You didn't have to."

He pulled out a chair and sat down across from me.

The table between us felt wider than it was.

"Three weeks ago," he said slowly, "Daniel asked me something strange.

He asked if Kayla was still single.

I told him I didn't know — you'd mentioned she'd broken up with someone, but I didn't have details.

He said he was just asking." Andrew paused.

"I didn't think anything of it."

"Three weeks ago," I repeated.

"That's before she called me crying.

Before she showed up with two suitcases."

Andrew's jaw tightened.

"Yes."

I let that sit between us.

Kayla had called me in tears.

Nowhere to go, no money, nothing.

I had opened my door without a second thought because she was my sister and that's what you do.

But the timeline was wrong now.

The timeline had been wrong from the beginning and I hadn't seen it because I hadn't been looking.

"She wasn't thrown out," I said.

Andrew didn't answer.

"She planned to come here."

He still didn't answer, which was its own kind of answer.

Upstairs, I heard a door open.

Footsteps crossed the ceiling above us.

Then the stairs creaked, one by one, and Kayla appeared in the kitchen doorway with her hair damp and her expression carefully reset — the face of someone who had just spent five minutes deciding what face to wear.

She looked at me.

Then at Andrew.

Then back at me.

"I'm going to start looking for an apartment this week," she said.

"I just wanted you to know I'm taking this seriously."

Andrew looked at her with an expression I had never seen on him before.

Not anger.

Something quieter and more precise than anger.

"Sit down, Kayla," he said.

She blinked.

"I was just going to make some tea —"

"Sit down."

She sat.

Andrew leaned forward, both forearms on the table, and looked at her steadily.

"How long have you been talking to Daniel?"

The color left her face so fast it was almost impressive.

"I don't know what you mean."

"I think you do."

"Andrew, I barely know your brother —"

"Then it'll be a very short conversation." He didn't raise his voice.

"How long?"

Kayla looked at me.

I looked back at her and said nothing.

She looked down at the table.

"Two months," she said quietly.

The kitchen was completely silent.

Two months.

She had been talking to Daniel for two months.

She had been planning this for two months.

The crying phone call, the two suitcases, the $300, the towel — all of it arranged, all of it deliberate, while I thought I was rescuing my sister from the worst moment of her life.

"Get out," I said.

Kayla looked up.

"Please, just let me explain —"

"I want you out of my house by tonight."

Her eyes filled.

"You don't understand what's been happening.

Daniel and I — it's not what you think.

We didn't mean for any of this —"

"I said tonight."

She stood up slowly.

At the doorway she stopped and turned back, and for just a moment her expression cracked into something that looked almost like the sister I thought I knew.

"I'm sorry," she said.

"I really am."

I didn't answer.

She went upstairs.

Andrew reached across the table and covered my hand with his.

I turned my hand over and held on.

Neither of us said anything for a long time.

Then his phone buzzed on the counter.

He picked it up, looked at the screen, and went very still.

It was a text from Daniel.
