My Husband’s Mistress Was Carrying His Rival’s Child

Two days before the surgery, a violent thunderstorm swallowed Manhattan. At three in the morning, the penthouse was a cavern of shadows, illuminated only by the jagged flashes of lightning tearing across the floor-to-ceiling windows.

Beside me, Maddox slept a drugged, shallow sleep. His breathing was a wet, rattling sound that usually kept me awake with worry. Tonight, it was the sudden, sharp buzz of his phone on the nightstand that pulled me from my restless doze.

The screen glowed with a harsh blue light. I reached over him to silence it, not wanting his rest disturbed. But as my fingers grazed the glass, the notification banner caught my eye.

*B: Can’t sleep. Thinking about the watch. Thinking about after.*

My blood turned to slush in my veins. *B.* Briella. The watch. The heavy, intimate engraving.

My hand trembled as I slid the phone from the charging dock. I knew his passcode—our anniversary. The screen unlocked, opening directly to their message thread. It wasn't just a few texts. It was an endless, damning scroll of late-night promises, hotel room numbers, and explicit photographs that made the bile rise in my throat. My thumb swiped upward, moving months back, a year back.

Then, I saw the audio files.

I slipped out of bed, my bare feet silent against the cold hardwood, and retreated into the master bathroom. I locked the heavy oak door, sinking onto the heated marble floor. With a shaking finger, I pressed play on a voice memo dated three weeks ago—the day after Maddox’s diagnosis.

Maddox’s voice filled the tiled room. It wasn't the weak, raspy tone he used with me. It was crisp, arrogant, and laced with a cruel amusement.

*"Relax, Brie. It’s handled. Let her play the savior, get the kidney, then we file for divorce and take the trust fund. She's too stupid to read the fine print on the marital asset accounts anyway. Just wait it out."*

Briella’s signature sugary giggle echoed in the background.

I dropped the phone. It clattered against the marble.

The devotion that had anchored my soul for eight years didn't just fracture; it shattered into microscopic, razor-sharp shards. A violent, suffocating wave of nausea hit me. I scrambled toward the toilet, gripping the icy porcelain as I violently emptied my stomach. I gagged until there was nothing left but dry, agonizing heaves, my tears dripping into the bowl.

When I finally pushed myself up to the mirror, the woman staring back at me was a stranger. The pathetic, weeping wife who twisted her wedding ring in constant anxiety was dead. In her place stood someone entirely hollowed out, her veins running with liquid nitrogen. I looked down at the platinum band on my finger. I didn't twist it. I let the metal sit there, a shackle I was about to weaponize.

By noon, I was miles away from the Upper East Side, sitting in a cramped, windowless office in a Bronx clinic that smelled of stale bleach and cheap coffee.

Elena Rodriguez, a medical technician with exhausted eyes and a price tag, sat across from me. I didn't offer small talk. I simply unclasped the ten-carat diamond tennis bracelet Maddox had bought me for my thirtieth birthday and slid it across the scratched laminate desk.

Elena’s eyes darted to the diamonds, catching the flickering fluorescent light. She scooped it up, her movements practiced and quick.

"Six weeks," I told her, my voice eerily calm. "I need official blood work and a sonogram. Flawless. The kind that holds up to a private family physician's scrutiny."

Ten minutes later, I walked out into the humid city air holding a crisp, official folder. Inside was a glossy strip of thermal paper displaying a small, black-and-white cavern—a fabricated heartbeat. A phantom heir. I stared at the dark void on the paper, my jaw setting into stone.

That evening, the air in the penthouse living room was suffocatingly tense. Azalea Austin, Maddox’s grandmother, sat on the velvet sofa, her posture rigid as she sipped Earl Grey from a bone china cup. Ainsley paced the Persian rug, her heels clicking like a metronome of pure disdain.

"You look like a corpse, Lydia," Ainsley snapped, stopping to glare at me. "My son is the one facing the scalpel in forty-eight hours, yet you're the one dragging your feet around this penthouse. If you are too fragile for this procedure, you should have said so before we wasted our time."

Azalea scoffed softly, the sound barely clearing the rim of her teacup. "She’s just nervous, Ainsley. Common girls always lack the constitution for real sacrifice."

I sat perfectly still in the armchair, absorbing their venom. I let the silence stretch, letting it grow heavy and uncomfortable. Then, I reached into my designer tote and pulled out the clinic folder.

I dropped it onto the glass coffee table. It landed with a sharp, authoritative smack.

"I'm not fragile, Ainsley," I said, my voice barely above a whisper, yet it commanded the entire room. "I’m exhausted. The doctors warned me that the physical toll of the transplant could be catastrophic—not just for me, but for the baby."

Ainsley froze. The color drained from her perfectly contoured face. Azalea’s teacup rattled against its saucer, a sharp, porcelain clatter that betrayed her sudden shock.

"Baby?" Ainsley breathed, her eyes darting from my face to the folder on the table.

"Six weeks," I said, placing a protective hand over my flat stomach. I looked up, meeting Ainsley's terrified gaze. "I'm carrying Maddox's child. The next Wright heir. And if I go under the knife on Friday, the stress of the surgery will likely terminate the pregnancy."

The hostility in the room evaporated, instantly replaced by a desperate, suffocating panic. The hook was set. Now, it was time to bleed them dry.
