Chapter 6
I start watching Matt's phone.
Not taking it — I would never. Not going through it — I don't know his passcode and I've never wanted to. But watching. Noticing when it lights up. Counting the times he picks it up and smiles at something and doesn't tell me what it is.
Wednesday morning. He's making coffee. His phone is on the counter and it buzzes and I see the name before he picks it up.
Sophie.
He glances at it. Types something short. Sets it back down.
"Who was that?" I keep my voice light. Normal. Pouring oat milk into my mug.
"Sophie. Asking about that tomato fertilizer I mentioned."
"You guys text a lot about the garden."
He looks at me. "I guess? She asks questions. I answer them. Is that — are you being weird about this?"
"No. I'm not being weird."
"You sound weird."
"Matt. I'm not weird. I was just asking."
He holds my gaze for a second. Then shrugs. Picks up his coffee. "She's your friend. I'm just being friendly."
He's not wrong. From his perspective, everything is normal.
A woman he knows through his wife texts him occasionally about plants.
That's friendship. That's being neighborly.
He doesn't know about the nine aliases. He doesn't know about the hard drive with his wife's name written in someone else's handwriting.
And I can't tell him. Not yet. The group said wait. Cara said: If she senses anything, she runs.
So I smile. "I know. Sorry. I'm tired."
"You didn't sleep well?"
"No."
"You should take something."
"Yeah. Maybe."
He kisses my forehead and leaves for work and I sit at the kitchen table with my coffee growing cold and I open my phone and count.
Fourteen texts between Matt and Sophie in the last seven days. I can see the thread if I pull his messages up on the family iPad we share — we set it up years ago for grocery lists, never thought to restrict anything. The messages are all there.
Monday: Sophie sends the shakshuka recipe. Matt replies: Looks great, will try tonight.
Monday: Sophie replies with a photo of hers. It's ugly but it tasted amazing lol.
Tuesday: Matt asks about the community garden committee meeting. Sophie says: Boring. They voted no on chickens. I'm devastated.
Wednesday (today): Sophie asks about tomato fertilizer. Matt recommends fish emulsion. Sophie: That sounds disgusting. Matt: It is. It works.
Thursday (last week): Sophie asks if he's going to the garden. Matt: Quick stop before hardware store. Sophie: I'll be there! Come say hi.
Thursday: Matt: Your nitrogen levels look low. Try adding blood meal. Sophie: You're my garden hero ??
Friday: Sophie sends a photo — her plot, the basil looking lush. Matt: Damn. That's gorgeous. Sophie: Right?? It loves the afternoon sun.
Saturday: Sophie: Tell Priya I'm wearing yellow so she has to match!! Matt: lol will do. Sophie: You should come! Market is fun. Matt: I'll try, work might keep me.
Saturday: Sophie: We missed you!! Your wife bought a million peppers. Matt: She'll turn them into something amazing. She always does. Sophie: She's incredible. You're lucky.
Fourteen texts. Seven days. None of them are inappropriate. None of them are sexual or suggestive or even flirtatious in a way I could point to. They're warm. They're friendly. They're exactly what texts between your wife's friend and your husband should look like.
Except for the frequency. Fourteen texts in seven days with a woman he's known for two months. That's twice a day. Matt texts his own brother maybe three times a week.
And except for the pattern I can see now that I know to look — Sophie always initiates.
Sophie always asks a question that requires a response.
Sophie always compliments him or asks for his help or reflects him back as competent and knowledgeable and generous.
You're my garden hero. You're lucky. She's building something.
Slowly. One text at a time. A structure made of small interactions that individually mean nothing but collectively create proximity.
In flavor science, we call this the threshold effect.
A single compound below its detection threshold is invisible — you can't taste it, can't smell it, it might as well not be there.
But add a second compound also below threshold, and a third, and a fourth — and suddenly the combination crosses into perceptibility.
Not because any one element is strong enough to notice, but because they're additive. They build.
Sophie's texts are below threshold. Each one is nothing. Together, they're building toward something.
I close the iPad. Put it back on the charger. Go to work.
At work, I can't focus. I'm supposed to be running regression analysis on the sensory data from last week's panel — correlating texture scores with purchase intent — but I keep opening new tabs. Googling things.
Serial friendship predator.
Woman targets married couples.
Obsessive friendship behavior.
The results are thin. A few Reddit threads.
A psychology article about "pathological enmeshment.
" A podcast episode about a woman who befriended three couples on her street and slept with all three husbands.
Comments underneath: That's not a thing.
Women don't do this. And: This happened to me. No one believed me.
I search "Sophie Keller Atlanta." Nothing useful.
A Sophie Keller who's a financial planner in Buckhead.
A Sophie Keller who graduated from Emory in 2014 — wrong age, wrong face.
No social media for my Sophie. I knew that already — she told me early on she deleted everything.
"For my mental health," she said. I thought that was admirable.
Self-aware. Now I think: convenient. No photos to reverse-image-search. No history. No digital footprint.
I search "Sophie Keller Portland." A LinkedIn profile with no photo — "marketing consultant, self-employed, Portland metro area.
" Last updated 2023. No connections visible.
No posts. A ghost account. The kind of profile that exists only to satisfy people who google you — to prove you're real, in the thinnest possible sense.
I find a term: social engineering. In cybersecurity, it means manipulating people into giving up confidential information. Pretexting. Baiting. Building false trust to exploit vulnerability.
That's what Sophie is doing. Social engineering. Except the target isn't a database. It's a marriage.
At lunch, I call Cara.
"How are you?" she asks.
"I checked his texts." I'm in my car in the parking lot. Air conditioning running. Doors locked. "They're not — there's nothing sexual. Nothing obvious. But she texts him every day. She always initiates. She always—"
"Asks for his help? Compliments him? Makes herself need him?"
"Yes."
"That's Stage 2. She did the same thing with Jake.
Same thing with Derek. Same thing with all of them.
Stage 1 is befriending the wife. Stage 2 is making herself visible to the husband through the wife's permission — using the friendship as cover.
Stage 3 is engineering alone time. Stage 4 is the affair. "
"What stage am I in?"
"Late Stage 2. He's comfortable with her. She has a channel to him. She's starting to create reasons to be alone with him — the Thursday garden visit. The next step will be something bigger. She'll offer to help with something. A project. A favor. Something that puts them together without you."
I press my forehead against the steering wheel. The leather is hot from the sun.
"When are you coming?" I ask.
"Friday. Rachel's booking flights tonight. Me, Rachel, and Danielle."
"What about the others? The other women?"
"Some will come. Amy, maybe. Lauren. It depends on work, on lives. But for now — the three of us. We'll be in Atlanta Friday night."
Today is Wednesday. Two more days. Two more days of normal. Two more days of Sophie texting my husband and me smiling and saying nothing.
"Can you do it?" Cara asks. "Two more days?"
I think about Tuesday. Sophie in my kitchen. Drinking my wine. Do you guys fight? I think about the profile. Lonely. Eager for connection.
"I can do it."
"Don't look at his phone again. It'll drive you crazy and you'll slip. Just — be normal. Go to work. Text Sophie back. Breathe."
"Okay."
"And Priya? You're not alone anymore. I know it feels like you are. But you're not."
I hang up. Sit in the car for ten more minutes. Then I go back inside and I run my regression analysis and I pretend to be a person whose life isn't being disassembled from the inside by a woman who calls her flavor queen.
That evening, Sophie texts me: Thursday yoga still on? I'll save you a spot!
I type back: Wouldn't miss it! ???♀?
And I press send and my thumb leaves the screen and I taste something sharp and acidic at the back of my throat — the taste of performing a friendship I now know is a lie.
The same taste Sophie has been feeding me for two months.
Synthetic. Convincing. And built from nothing real at all.
