Heard Through the Walls

I sat in my home office until nearly midnight, staring at screenshots of hotel charges and restaurant bills, my mind racing with possibilities. The recording had mentioned something specific—something that might help me identify Derek's mistress.

"The product launch next week."

I replayed those words in my head. Derek's company was always launching something, but there was only one major product launch scheduled for next week. Their new AI analytics platform—the one Derek had been obsessing over for months.

Which meant she worked at his company.

I opened a new browser window and navigated to TechNova Solutions' website. The "Our Team" page loaded slowly, revealing rows of polished headshots and carefully crafted bios. I scrolled past the executive team—all men Derek's age or older—and focused on the department heads.

There. Head of Product: Mia Chen.

My breath caught. She was beautiful in that effortless way that came with being twenty-eight and brilliant. Stanford MBA, according to her bio. Five years at Google before joining Derek's company. In the professional headshot, her dark hair fell in perfect waves past her shoulders, and her smile was confident, magnetic.

I remembered Derek mentioning her name in interviews, always with a particular enthusiasm in his voice. "Mia Chen is the most valuable talent we've ever recruited," he'd said in a TechCrunch article last month. "She's revolutionizing how we think about product development."

My hands shook as I clicked on her LinkedIn profile. Two hundred thousand followers. Keynote speaker at three major conferences this year. A rising star in the tech world, everything I used to be before I chose family over career.

Before I chose Derek over myself.

I hesitated for a moment, then opened Instagram and searched for her name. Her profile was public—of course it was. Beautiful, successful people like Mia Chen didn't hide from the world.

The photos told the story of a life I barely remembered living. Rooftop dinners with gorgeous friends. Weekend trips to Napa and Big Sur. Designer clothes and artfully arranged coffee cups. The kind of curated perfection that came from having something worth showing off.

I scrolled back through her posts, my heart hammering against my ribs. Three weeks ago: a photo of her in a black cocktail dress at some tech industry gala. "Celebrating another successful quarter with the team! 🥂" Derek was visible in the background, his hand resting on her lower back.

Two weeks ago: "Sunday morning vibes ☕️✨"

The coffee cup sat on a familiar surface. White quartz countertops with subtle gray veining. Behind it, barely visible in the background, was a backsplash of handmade ceramic tiles in soft sage green.

Tiles I'd spent three weeks choosing when we renovated our kitchen five years ago.

Tiles that were currently behind me, in my own kitchen, in my own home.

She'd been here. In my house. Drinking coffee in my kitchen while I was... where had I been that Sunday morning two weeks ago? Taking Emma to her soccer game. Jake had stayed home with Derek, claiming he felt sick.

Derek had texted me during the game: "Jake's feeling better. We're just hanging out at home."

We. He'd said we.

I stared at the photo until my eyes burned, memorizing every detail. The expensive coffee mug—not one of ours. She'd brought her own. The perfectly manicured nails wrapped around the handle. The soft morning light filtering through the kitchen window I'd watched thousands of sunrises through.

My kitchen. My home. My life.

I kept scrolling, looking for more evidence, more proof of this betrayal that was somehow both shocking and inevitable. But the coffee photo was the only glimpse into her private moments with my husband. Everything else was carefully curated professional success and social media perfection.

I clicked back to the photo and studied the timestamp. 9:47 AM. Right around the time Derek usually made his morning coffee, using the expensive espresso machine I'd bought him for his birthday three years ago.

The machine he'd probably used to make coffee for her.

I closed Instagram and sat in the dark office, my laptop screen the only source of light. The house was silent around me—Derek still at his "investor calls," the kids asleep upstairs, dreaming innocent dreams in their perfect bedrooms.

Mia Chen. Twenty-eight years old. Stanford MBA. Head of Product. The woman my husband was planning to leave me for.

The woman who'd stood in my kitchen, in my space, probably laughing about how clueless I was. How boring. How easy it would be to replace me.

I pulled out my phone and scrolled through my contacts until I found the number I'd saved earlier. My finger hovered over the call button for a long moment.

Then I pressed it.

The phone rang twice before a professional voice answered. "Law Office of Caleb Mercer, after-hours answering service. How may I help you?"

"Hello," I said, surprised by how steady my voice sounded. "I need to schedule a confidential consultation with Mr. Mercer. It's urgent."

"Of course. May I ask what this is regarding?"

I looked at the Instagram photo still open on my laptop screen—Mia Chen's perfect smile, her coffee cup on my countertops, her life intersecting with mine in the most devastating way possible.

"Divorce," I said. "High-asset divorce. And I need it handled discretely."

"I can schedule you for tomorrow morning at nine AM, if that works?"

"Perfect."

"May I have your name for the appointment?"

I paused, staring at my reflection in the dark window. The woman looking back at me wasn't the same person who'd woken up this morning believing in her perfect marriage.

"Nora Peterson," I said. "And please make sure Mr. Mercer knows this is extremely time-sensitive. My husband is planning to leave me, and I intend to leave him first."
