She showed up at my door shaking—my twin sister—covered in bruises she tried to hide with long sleeves. “Don’t… don’t ask,” she whispered. But I did. And when I learned it was her husband, my blood turned to ice. That night, we switched places. He leaned in, smug, murmuring, “Finally learned to behave?” I smiled like her—and answered like me: “No. I learned how to bite.” When the lights went out, he realized the wife he broke… wasn’t the one in the room anymore.

Chapter 1: The Midnight Ghost

The rhythmic, frantic rapping against my front door commenced precisely at eleven-fourteen, fracturing the humid, stagnant silence of the night. It wasn’t a polite neighborhood knock; it was sharp, erratic, and desperate, sounding as though whoever stood on my porch had suddenly forgotten the basic mechanics of their own hands.

I approached the entryway with a heavy dose of caution, fully expecting to find a lost delivery driver or perhaps a severely intoxicated local who had wandered down the wrong street. I twisted the deadbolt and pulled the door inward.

Instead of a stranger, I found a ghost standing under the flickering amber glow of my porch light. It was my identical twin sister, Emily.

She was vibrating with a tremor so violent I could audibly hear her teeth clicking together. Her hair, which she religiously maintained in a pristine, professional chignon for her corporate job, hung in a wild, tangled curtain around her pale face. Despite the oppressive summer heat radiating off the asphalt, she was buried inside an oversized, heather-gray sweatshirt, paired with faded denim and scuffed sneakers. The sleeves were pulled down to her knuckles, attempting to swallow her hands entirely.
