My husband cooked dinner, and for one strange hour, the house looked like the version of our life I had spent years trying to protect.

The metallic screech of the garage door vibrating against the tracks sounded like a siren in the dead silence of the house. Every gear, every clank of the aging motor echoed through the walls, signaling that our executioner had returned before his plan could naturally conclude.

My mind raced. Why was he back? Had he forgotten something crucial? A passport? His car keys? Or had he realized that the front door lock clicked a little too loudly, or that my breathing didn't match the rhythm of a paralyzed body?

Beside me, Caleb pressed his face into the rough fibers of the rug, his small body trembling violently. I could feel the rapid, frantic beat of his pulse against my fingertips where our hands were still clasped together.

'Breathe, baby,' I mouthed silently, my own lungs burning from the faint, sickly sweet scent of propane beginning to bleed out from the basement vents and seep into the open-plan kitchen and living room. The gas was a secondary insurance policy. If the heavy sedative in the chicken didn't stop our hearts, the invisible vapor filling the lower level would ensure that any emergency responders arriving hours later would chalk our deaths up to a tragic, catastrophic household leak.

Footsteps echoed on the concrete floor of the garage. Heavy. Deliberate.

Ethan had left his duffel bag in the trunk, or perhaps he had remembered the insurance papers sitting inside his office desk drawer—documents that would make him the sole beneficiary of our modest home, my life insurance policy, and the savings account I had spent a decade building from my freelance design work.

I forced my eyelids to remain half-closed, creating a microscopic slit through which I could watch the entryway. The interior garage door clicked as the handle turned.

Ethan stepped into the kitchen, his silhouette framed by the harsh, fluorescent yellow light of the garage overhead bulbs. He didn't look like a grieving husband. He looked cold, efficient, and detached. He walked straight toward the kitchen island, bypassing our unconscious-looking bodies entirely.

I heard the rustle of paper. He was grabbing the manila folder.

'Stupid,' he muttered under his breath, his voice dripping with venom. 'Always leaving things where I can see them.'

He tucked the folder securely under his arm, his eyes scanning the room one last time to ensure everything looked undisturbed. His gaze lingered on Caleb for a fraction of a second—long enough for me to stop breathing entirely—before he turned back toward the garage door.

As he stepped back out, the electronic motor engaged again, lowering the heavy metal door with a dull thud.

The moment the lock clicked shut, I scrambled onto my hands and knees, fighting through the residual dizziness and numbness creeping through my limbs from the drug.

'Caleb, up. Now,' I whispered, my voice harsh and breathless.

My son pushed himself up, his eyes wide with a terror no ten-year-old should ever have to experience. 'Mom, the air... it smells weird.'

'I know. We have to get out.'

I didn't head for the front door. Ethan knew which way the wind blew; he might be waiting in his car at the end of the long driveway, watching to see if anyone staggered out into the night. Instead, I grabbed Caleb's hand and pulled him toward the back patio sliding door that led straight into the enclosed, high-fenced backyard.

The lock was stiff, rusted from the winter moisture, but adrenaline was a powerful stimulant. I threw my weight against it, sliding the glass panel open with a sharp rattle that cut through the night air.

We tumbled out into the crisp evening breeze, gasping in great, lung-fulls of clean, sweet oxygen. The cool air shocked my system, burning my throat but clearing the dense fog in my brain.

'Keep low, stay near the fence line,' I instructed, pulling Caleb behind the thick wall of evergreen bushes that bordered our neighbor's yard.

As we crouched in the damp mulch, I pulled out my phone from my pocket. My hands shook so badly I dropped it twice before managing to unlock the screen. My fingers hovered over the keypad, ready to dial three numbers that would change our lives forever.

Then my screen lit up with a text message from an unknown number.
