My Fated Mate Poisoned Me for His Mistress

That night, Joel was fast. He leaned out the driver's window, muttered something about an early supply run to the butcher in town, and Barrett waved him off without a second glance. The van rumbled through the gates, taking Buster with it. The only clean thing left in my life was finally outside these walls.

Over the next three weeks, I made myself a ghost.

I kept my chin tucked to my collarbone. I let my shoulders round forward. Whenever Barrett entered a room, I shrank back toward the drywall, making my breathing shallow and ragged. When he spoke to me, I answered in the same flat, hollow monotone he had beaten into me with his Alpha tone.

He loved it. To him, my silence meant absolute defeat.

Because he thought I was harmless, he put me to work. He didn't want the staff talking, so he assigned me menial chores to keep me out of sight. I swept the basement corridors. I filed dusty territory ledgers in the back office. I carried trays of black coffee and dry beef to visiting Betas who looked right through me like I was a piece of broken furniture.

They didn't realize I was taking inventory.

Every time I carried a mop bucket or an armload of files, my eyes mapped the house. Fourteen digital security cameras covered the main floor. Eight swept the basement perimeter. Declan had the guards running two-hour staggered shifts, with a four-minute gap during the changeover at the service entrance.

More importantly, I found the gaps.

There were three completely dead zones where the lens angles failed to cross. The first was the northeast supply corridor behind the old boiler room. The second was the cold storage annex tucked behind the industrial kitchen, shielded by heavy aluminum racks. And the third was beneath the east wing floorboards—a rusted storm-drain maintenance hatch left over from the original estate built seventy years ago. It didn't appear on any modern blueprint Barrett possessed. It led straight out into the ravine behind the tree line.

A way out. When the time came.

While I built my map, Nina worked hard to secure her place.

In public, she played the triumphant new mate to perfection. Barrett made me sit at the far end of the long dining table during formal dinners, where Nina never missed an opportunity to display her dominance.

"Look at her plate, Barrett," Nina said one evening, poking a silver fork into her roasted duck. "She barely touches anything. It's a waste of food. Give her broth tomorrow. An invalid doesn't need meat."

Barrett smiled thinly and nodded to the kitchen staff. "Broth it is."

Nina smirked at me down the length of the mahogany table. Two nights later, when I walked onto the stone terrace to shake out the dining room linens, I heard the heavy latch drop behind me. It was twenty-eight degrees outside. She had "accidentally" locked the deadbolt. I had to sit against the freezing stone wall for four hours before a sleepy Omega unlocked it before dawn.

Barrett saw my blue lips at breakfast and said nothing. He liked seeing me put in my place.

I absorbed every petty strike without blinking. But as the days passed, I started watching Nina with a cold, focused eye. And things didn't add up.

Her pregnancy was too loud. She only suffered from morning sickness when Barrett walked into the room or when older pack matrons were within earshot. In private, when she thought no one was looking, she moved quickly. Her balance was centered. There was none of the awkward, heavy gait typical of a she-wolf carrying an Alpha's heir in her second trimester. Her stomach looked round beneath loose knit sweaters, but in silk, the curve sat stiff and unnaturally high.

Then came Thursday night.

I was carrying a stack of archived payroll sheets past Nina's suite on the second floor. It was two in the morning. The hallway was completely dark. As I passed her door, the central heating kicked on, pushing a draft of warm air from under the wood.

I stopped in my tracks.

I didn't have my wolf, but my human senses were razor-sharp from years of hypervigilance. The scent wafting out of her room wasn't the thick, milky sweetness of pregnancy hormones.

It smelled like chemical adhesive. Resin. And the distinct, powdery rubber scent of medical-grade silicone.

My breath caught in my throat. I stood frozen in the dark hallway, staring at the brass numbers on her door.

*She isn't pregnant.*

The realization hit me like a splash of ice water. Nina wasn't carrying Barrett’s heir. The belly was fake. The nausea was fake. The whole performance was a lie.

I committed the chemical scent to memory, turned on my bare heels, and walked silently down to the basement. I didn't know why she was doing it yet, but it was leverage. A secret that could shatter Barrett’s grand plan.

The next morning, the cage slammed shut a little harder.

Heavy boots pounded down the concrete steps of the basement, stopping right outside my room. The deadbolt slid back with a harsh clatter, and Declan Hoffman stepped inside. He filled the small doorway, his broad shoulders blocking the hallway light.

He held a clipboard and a cheap ballpoint pen.

"New orders from Alpha Barrett," Declan said, his voice flat and devoid of emotion.

He tossed a typed sheet onto my thin wool blanket. I picked it up. It looked like an intake sheet from a maximum-security prison.

My room would be inspected twice daily. All incoming and outgoing mail was permanently revoked. I was strictly forbidden from stepping past the gravel driveway without an armed Beta escort. Any breach of these rules would result in an immediate return to the cellar.

"Sign at the bottom," Declan said.

I picked up the pen. My fingers didn't shake. I signed my name in neat, even cursive and handed the board back to him.

"Of course, Beta Declan," I said. My voice was smooth, quiet, completely blank.

Declan didn't leave. He stood there, holding the clipboard, his dark eyes narrowing as he studied my face. He had been Barrett’s top enforcer for ten years. He knew violence, and he knew fear. What he didn't know was total, effortless surrender.

"You don't argue anymore, Cassandra," he muttered, tilting his head.

"What is there to argue?" I looked at the floor between his boots. "The Alpha provides what is best for my recovery."

Declan lingered for another ten seconds, trying to catch a twitch in my jaw, a flare in my nostrils, anything. When he found nothing, he grunted, turned on his heel, and pulled the heavy door shut behind him.

I heard him walk up the stairs. A minute later, his voice drifted faintly through the ventilation grate near my ceiling. He was speaking to Barrett in the ground-floor hallway.

"She’s too quiet, Barrett," Declan warned, his tone low and tense. "A wolf that's beaten usually cowers or snaps. She just signs the paper. It feels wrong."

Barrett’s harsh, arrogant laugh echoed through the metal duct.

"You worry too much, Declan," Barrett sneered. "I put three years of wolfsbane into her veins. She has no wolf. She has no pride. She has nothing. Let her rot in the basement."

"Still," Declan's voice remained hard. "I'm doubling the corridor guard."

I sat on the edge of the metal cot, staring at the silver-sealed window as the sound of their footsteps faded away. Ten minutes later, the heavy thud of two sets of combat boots began pacing outside my door, a rhythmic, unbroken loop.

Declan was right to be nervous.

I slid my fingers inside my sleeve, feeling the tiny glass vial of wolfsbane pressed cold against my skin. They thought I was an empty shell waiting to die.

They had no idea the clock was already ticking.
