My Husband’s Mistress Is Carrying Quadruplets

The fluorescent lights in the lab hum at a frequency that most people can't hear, but I've worked here long enough that the sound lives in my bones. I adjust the microscope stage, my fingers moving with the kind of precision that comes from five years of analyzing genetic material down to the nucleotide. The junior analyst—Marcus, fresh out of grad school—hovers at my elbow, watching me correct his sample prep with the nervous energy of someone who knows they've made a mistake but doesn't yet understand how costly mistakes can be in this field.

"See this?" I tap the screen where his gel electrophoresis shows smearing. "You didn't let the samples equilibrate to room temperature. The proteins degraded."

He nods, scribbling notes, and I feel the familiar satisfaction of catching an error before it becomes a problem. Control. Precision. These are the pillars of my work, the things that make me one of the most trusted DNA analysts in Seattle.

My supervisor, Dr. Reeves, appears in my peripheral vision, holding a manila folder with a red "Priority/VIP" sticker. "Elise, I need you on this one. Rush paternity test. Client paid for the expedited processing."

I take the folder, flipping it open. The mother's name is listed as Leyla—no last name provided, which isn't unusual for sensitive cases. The alleged father is marked "John Doe," sample already logged and waiting in cold storage. Standard procedure for clients who want anonymity.

"When do they need it?"

"Tomorrow morning. Mother's coming in personally to collect."

I glance at the clock. Four-thirty. If I start now, I can have preliminary results by midnight, full report by morning. "I'll handle it."

The lab empties as evening shifts end. I prefer working alone anyway—no small talk, no distractions, just me and the elegant language of base pairs and alleles. I retrieve the samples from storage: maternal blood, fetal DNA extracted from a prenatal screening, and the alleged father's cheek swab in a sealed vial.

The sequencer whirs to life, and I load the samples with the same methodical care I bring to everything. PCR amplification takes two hours. I spend the time reviewing case notes, drinking black coffee from my thermos, organizing my workspace. The leather portfolio where I keep my personal files sits in my bag, and I think about Harrison, probably still at the office, chasing whatever deal he's obsessed with this week. We have dinner reservations at eight that I know he'll cancel.

At eleven-forty, the sequencer beeps. I pull up the results on my monitor, watching the genetic markers populate across the screen in neat columns. The maternal match is clean—99.99% probability. Now for the paternal comparison.

I run the algorithm, and the markers begin aligning. My eyes catch on a sequence in the D3S1358 locus—a rare allele combination, fourteen and eighteen repeats. I've only seen that pattern once before.

My hand freezes on the mouse.

No. That's not possible.

I pull up our calibration database, the file I created three years ago when we upgraded our equipment. Harrison had volunteered his DNA as a known sample for quality control. I'd thought it was sweet at the time, him supporting my work.

I overlay the files.

D3S1358: 14, 18. Match.

vWA: 16, 17. Match.

FGA: 21, 24. Match.

Thirteen loci. Thirteen perfect matches.

Combined Paternity Index: 99.99%.

The biological father of Leyla's unborn child is Harrison Myers. My husband.

The lab is silent except for the hum of refrigeration units and the sudden roar of blood in my ears. I stare at the screen until the numbers blur, then refocus, then blur again. I run the analysis twice more, checking for contamination, for sample mix-up, for any possible error.

There is no error.

I don't cry. I don't scream. I sit in my ergonomic chair under fluorescent lights and feel something inside me calcify into something harder than bone.

The next morning, I arrive at the lab at eight-fifty-five, five minutes before Leyla's appointment. I've printed the results in a sealed envelope, my signature and credentials embossed on the lab letterhead. Professional. Unimpeachable.

She walks in at nine exactly—young, maybe twenty-five, with the kind of careless beauty that comes from never having to work for anything. Her hand rests on a barely visible bump beneath a designer dress I recognize from last month's Vogue.

I introduce myself as the senior analyst and lead her to a private consultation room. She sits, crossing her legs, and I notice the diamond bracelet on her wrist. Tiffany. Harrison bought me the same one for our anniversary.

"So?" She leans forward, eager. "Is he the father?"

I slide the envelope across the table. "Positive match. Ninety-nine point nine nine percent probability of paternity."

Her face lights up with triumph, and something ugly unfurls in my chest.

"I knew it," she says, more to herself than to me. "He's been so desperate for this. For a son. He said his wife refuses to give him children, that she's too focused on her career." She laughs, sharp and bright. "He's trapped in a loveless marriage, you know. But now—now everything changes."

I keep my face neutral, clinical. "When was conception?"

She pulls out her phone, scrolling. "February fourteenth. Valentine's Day. Very romantic, actually. He took me to this amazing restaurant, then back to the penthouse he bought for us."

February fourteenth.

The night I was alone in the ER at Swedish Medical Center, hemorrhaging from an ectopic pregnancy that ruptured my fallopian tube. The night I called Harrison six times and got voicemail. The night the surgeon told me I was lucky to be alive while I signed consent forms with shaking hands, no one holding the other one.

The night Harrison texted me at two AM: "Sorry, babe. Client dinner ran late. See you tomorrow."

Leyla is still talking, but I don't hear the words anymore. I hear only the hum of fluorescent lights and the sound of my own breathing, steady and controlled.

"Congratulations," I say, and my voice doesn't shake. "The father will be notified per standard protocol."

She takes the envelope and leaves, and I sit alone in the consultation room, my hands folded on the table, my wedding ring catching the light.

I don't take it off. Not yet.

First, I'm going to need more evidence.
