Corrie locked the door of the freezing, north-facing guest room.

She threw the cheap plastic bag onto the lumpy mattress. She reached inside and pulled out the royal blue knockoff dress.

She held it up by the shoulders. The harsh overhead light exposed every horrific flaw. The waistline was boxy, designed to fit a mannequin, not a human. The cheap rhinestones caught the light, glaring with a tacky, plastic shine.

Corrie's face remained entirely expressionless. She didn't feel panic. She felt the cold, clinical focus of a surgeon stepping up to the operating table.

She walked over to her canvas bag and unzipped a side pocket. She pulled out a pair of heavy, surgical-grade trauma shears. The blades were razor-sharp, designed to cut through leather boots and Kevlar in an emergency.

She walked back to the bed and laid the dress flat.

She didn't use chalk. She didn't measure.

Corrie grabbed the hem of the dress. The shears sliced through the cheap polyester with a sickening, tearing sound.

In less than three minutes, she amputated the bulky, ruffled sleeves, turning the top into a severe, asymmetrical halter.

She flipped the dress over. She drove the shears straight up the back seam, splitting the dress open down to the lumbar spine.

Next, her fingers moved like lightning. She gripped the glued-on rhinestones and violently ripped them off the fabric. The dry glue snapped and popped. She tore off hundreds of them, leaving only a cluster of the least offensive stones near the collarbone to act as a focal point.

She reached into her bag again and pulled out a spool of thick, black silk ribbon she used for tying off surgical tourniquets.

She stripped off her clothes. The cold air raised goosebumps on her pale skin.

She pulled the butchered blue fabric over her head. It hung loose and shapeless.

Corrie reached behind her back. She threaded the black silk ribbon through the raw, cut edges of the open back. She pulled the ribbon tight.

The fabric shrieked in protest, but the transformation was instantaneous.

The violent tightening of the ribbon cinched the waist perfectly against her ribs. The excess fabric gathered and draped over her hips, forcing the cheap polyester to mimic the heavy, liquid flow of a mermaid silhouette.

She tied a complex, brutal knot at the base of her spine, reaching into her bag one last time. Her fingers brushed past the stacks of cash and closed around the heavy, antique sapphire brooch George had given her. She pinned the massive, flawless gemstone directly over the raw knot of the black silk ribbon. The heavy, old-money opulence of the Warren family heirloom clashed violently with the avant-garde, deconstructed rebellion of the dress, creating an absolutely breathtaking, jaw-dropping masterpiece.

She walked over to the cracked mirror hanging on the closet door.

The dress was no longer a cheap knockoff. The raw, frayed edges where she had cut the fabric gave it a dark, deconstructed, avant-garde aesthetic. It looked like a piece of high-fashion rebellion, clinging to her sharp collarbones and narrow waist with aggressive perfection.

She didn't touch the makeup Dean had left on the dresser. She turned on the sink, splashed freezing water onto her face, and aggressively rubbed her cheeks until the friction brought a natural, blood-red flush to her skin.

She gathered her long, raven-black hair and twisted it into a messy, severe knot at the nape of her neck, securing it with a single black pen.

She slipped her feet into a pair of plain, flat black leather loafers. No heels. She didn't need the height to look down on them.

Downstairs, the ballroom was a sea of suffocating wealth.

Dean Warren glided through the crowd in a deep purple velvet gown. She held a crystal flute of champagne, laughing musically at a joke told by a state senator. She was in her element, the undisputed queen of the Philadelphia social scene.

Near the grand staircase, Kelly was holding court.

"I swear to God," Kelly giggled, pressing a hand to her chest, surrounded by five other girls in pastel couture. "I bought it off a clearance rack next to a dumpster. It cost eighty-nine dollars. It's literally made of plastic. Wait until you see her. She's going to look like a cheap disco ball."

The girls erupted into vicious, high-pitched laughter.

Suddenly, the string quartet in the corner hit a discordant note and stopped playing.

The heavy, carved mahogany doors at the top of the grand staircase groaned open.

The sound of chatter in the ballroom didn't fade; it was violently decapitated. A suffocating, dead silence crashed over the room in a matter of seconds.

Corrie stepped out onto the landing.

The massive crystal chandelier above the stairs cast a brilliant, blinding spotlight directly onto her.

She stood there, looking down at the sea of upturned faces. The royal blue fabric clung to her body like a second skin. The raw, deconstructed edges of the dress screamed high fashion. The black silk ribbon trailing down her exposed back looked like a deliberate, dangerous statement.

She wore no diamonds. No pearls. But the sheer, cold arrogance radiating from her posture made the women below look like they were wearing cheap costumes.

Kelly's jaw unhinged. The muscles in her face went slack.

Her hand jerked, and the champagne in her glass sloshed over the rim, splashing directly onto her pristine white Chanel dress. She didn't even notice. She stared up at the stairs, her eyes bulging with absolute, incomprehensible shock.

Dean's breath caught in her throat. A physical jolt of terror hit her chest.

For a split second, Dean didn't see Corrie. She saw Dolores. She saw the woman she had murdered, standing at the top of the stairs, looking down at her with the exact same aristocratic, untouchable disdain. Dean's fingernails dug so hard into her palms that they broke the skin.

In the center of the room, the editor-in-chief of a prominent New York fashion magazine pushed her glasses up her nose.

"Good lord," the editor whispered loudly in the silence. "Look at the draping on that bodice. The raw-edge technique... is that an unreleased Margiela? It's breathtaking."

Corrie began to walk down the stairs.

Her flat shoes made no sound on the carpet. She moved with a slow, predatory grace, her eyes locked dead ahead, completely ignoring the hundreds of people staring at her.

George Warren pushed his way to the front of the crowd. His chest swelled. A massive, overwhelming wave of pride washed over his face.

He stepped to the bottom of the stairs and held out his hand.

"Ladies and gentlemen," George announced, his voice booming with authority. "My eldest daughter. Corrie Warren."

A smattering of polite, awestruck applause broke out.

Kelly felt her blood boil. A hot, blinding rage consumed her brain. She couldn't let this happen. This was her night. This was supposed to be the moment she destroyed the rust-belt trash.

Kelly stomped forward, her heels clicking aggressively against the marble. She stopped right in front of Corrie, blocking her path.

Kelly forced a loud, shrill laugh that sounded like glass breaking.

"Oh my god, sister!" Kelly yelled, making sure her voice carried to the very back of the room. "I cannot believe you actually wore it! You are so brave for wearing an eighty-nine dollar clearance rack dress to a high-society gala!"

The applause instantly died.

The air in the room turned toxic. The socialites exchanged sharp, calculating glances. The awe in their eyes rapidly morphed into sneering condescension.

Dean closed her eyes for a second, a wave of dark relief washing over her. She stepped forward, playing the peacemaker.

"Kelly, please," Dean scolded softly, her voice laced with fake embarrassment. "We don't talk about price tags in polite company. Your sister doesn't know any better."

Corrie stopped. She didn't shrink back. She didn't look embarrassed.

She slowly tilted her head to the side. Her face was a mask of wide-eyed, innocent confusion.

"Price tags?" Corrie asked. Her voice was crystal clear, cutting through the silence like a knife. She looked directly at Kelly. "But Kelly, you told me this was the height of Warren family fashion. You said you used Dean's black Amex card to buy it specifically for me, so I wouldn't embarrass you."

The silence in the room became absolute. You could hear a pin drop.

Corrie took a step forward, raising her voice just a fraction, projecting it to the entire room.

"I thought it was a bit cheap for a billionaire's daughter to spend eighty-nine dollars on her sister's welcome-home gown," Corrie said, her tone perfectly flat, devoid of malice, stating it like a simple fact. "But I didn't want to seem ungrateful to my new mother."

A collective, audible gasp ripped through the ballroom.

The bomb had detonated.

The socialites turned their heads, their eyes locking onto Dean and Kelly. The looks of condescension were gone, replaced by absolute, unadulterated disgust.

Everyone in Philadelphia knew Dean Warren played the perfect, loving stepmother. And now, she had just been outed for forcing her biological daughter to buy the returning heiress a literal piece of garbage with a black card.

Whispers erupted like wildfire.

"Eighty-nine dollars?" a senator's wife sneered loudly. "How incredibly tacky."

"Did you see the way Kelly tried to humiliate her?" another whispered. "Pure trash."

Dean's face turned a violent, sickly shade of gray. The elegant, untouchable mask she had worn for eighteen years shattered into a million pieces. Her stomach churned with violent nausea. She felt the burning, judgmental stares of her peers stripping the flesh from her bones.

Kelly stood frozen, her mouth opening and closing like a suffocating fish. She looked around at her friends, but they all took a synchronized step back, distancing themselves from the radioactive embarrassment.

Corrie didn't smile. She didn't gloat.

She simply stepped around Kelly's frozen body, grabbed a glass of sparkling water from a passing waiter, and walked into the crowd, leaving her stepmother and sister burning in the ashes of their own trap.

The gala dragged on, but the atmosphere had permanently shifted.

The air in the ballroom felt thick, suffocating. The whispers followed Dean and Kelly everywhere they went, a relentless, buzzing swarm of social execution.

Corrie felt the heat of the room pressing against her skin. The smell of expensive perfumes and roasted meats was making her throat itch.

She set her half-empty glass of sparkling water on a silver tray. Without a word to anyone, she turned and walked toward the grand staircase, seeking the cold, empty air of the second-floor gallery.

She climbed the stairs, her hand trailing lightly against the polished mahogany banister.

Down below, Kelly was standing near the restrooms. Her face was stained with ruined mascara. Two of her closest friends had just made a pathetic excuse to leave her side, treating her like a leper.

Kelly looked up and saw Corrie's back disappearing onto the second-floor landing.

A violent, blinding surge of hatred exploded in Kelly's chest. Her blood pounded in her ears, drowning out the classical music. She lost every ounce of rational thought.

She grabbed the heavy skirts of her ruined Chanel dress and sprinted up the stairs, her heels digging viciously into the carpet.

Corrie was standing near the edge of the second-floor balcony, looking down at the crowd. The area was dimly lit, far away from the chandeliers.

"You bitch!"

The venomous hiss came from right behind her.

Corrie didn't jump. She slowly turned around.

Kelly was standing three feet away. Her chest was heaving, her face contorted into an ugly, unrecognizable mask of pure rage. Spittle flew from her lips as she breathed.

"You did that on purpose," Kelly snarled, her voice a ragged whisper. She took a step closer, invading Corrie's personal space. "I stood behind the heavy velvet curtain of the second-floor window and watched you step out of that car on your first day," Kelly hissed, her eyes wild with manic hatred. "I saw the cheap dirt on your boots. I knew immediately you were a parasite!" "You humiliated my mother. You ruined my life in front of everyone!"

Corrie looked at her. She didn't see a threat. She saw a pathetic, rabid dog barking at a wall.

Corrie took a sip of her water. The ice clinked softly against the glass.

"You bought the trash, Kelly," Corrie said, her voice a dead, emotionless flatline. "I just wore it. If the truth ruins your life, maybe you shouldn't be such a cheap, malicious little brat."

The words hit Kelly like a physical slap to the face.

Kelly's eyes darted wildly. She looked over the balcony railing. Down below, directly in their line of sight, a group of wealthy investors and their wives were looking up, their attention drawn by Kelly's aggressive posture.

A dark, psychotic light flashed in Kelly's eyes.

If she couldn't win the social war, she would destroy Corrie's life.

Kelly lunged forward. She threw her hands out and clamped her fingers around Corrie's left wrist. Her acrylic nails dug brutally into Corrie's skin, drawing tiny beads of blood.

Corrie's combat instincts flared instantly. Her muscles coiled. Her right hand twitched, ready to deliver a palm strike to Kelly's throat that would crush her windpipe.

But Corrie's hyper-vigilant brain processed the angle, the audience below, and the psychotic gleam in Kelly's eyes in a fraction of a second.

She aborted the strike. She froze her body completely, turning herself into a statue.

Kelly threw her head back. She opened her mouth and let out a blood-curdling, ear-piercing scream that ripped through the ballroom, shattering the polite chatter. The string quartet below abruptly stopped playing in shock, plunging the cavernous space into a sudden, deadly silence.

In that perfectly timed void, Kelly violently ripped her own hands away from Corrie's wrist and hurled her upper body backward.

"Corrie, no! Please don't push me!" Kelly shrieked as she fell, her voice echoing perfectly off the vaulted ceilings for every single guest to hear.

She intentionally threw herself down the grand staircase.

Her body hit the first carpeted step with a heavy thud. She tumbled backward, her limbs flailing, her expensive dress tearing as she rolled violently down the steep incline.

She hit the marble floor at the bottom of the stairs with a sickening, bone-jarring crack.

The entire ballroom erupted into absolute chaos.

Women screamed. Glasses shattered on the floor.

"Kelly!"

Dean's voice tore through the room, a raw, animalistic shriek of terror. She shoved past a waiter, sending a tray of champagne crashing to the floor, and threw herself onto the marble next to her daughter.

Kelly lay crumpled on the floor. A thin stream of dark red blood trickled from a gash on her forehead, staining the white marble. She was crying hysterically, her body shaking.

Kelly lifted a trembling, blood-stained finger. She pointed straight up the stairs.

"She pushed me," Kelly sobbed, her voice echoing in the dead silence of the horrified crowd. "Corrie tried to kill me."

Hundreds of eyes snapped upward.

They locked onto Corrie, who was standing perfectly still at the top of the stairs, a glass of water still in her hand.

The whispers instantly turned into a roar of condemnation.

"Monster," a woman hissed.

"Call the police! She's a psychopath!" a man yelled.

George Warren pushed through the crowd. His face was purple with rage. The veins in his neck bulged against his collar. He took the stairs two at a time, his heavy footsteps shaking the wood.

He reached the landing and stopped inches from Corrie's face.

"What have you done?!" George roared, his spit hitting Corrie's cheek. His hands were shaking so violently he looked like he was having a seizure. "Are you insane?! You tried to murder your sister?!"

Brad ran to the bottom of the stairs, pointing up. "Throw her out! Lock her up! She's a freak from the slums!"

Corrie looked at George's purple face. She looked down at Dean, who was cradling Kelly, shooting Corrie a look of absolute, victorious venom.

Corrie didn't panic. Her heart rate didn't even elevate.

She took a slow, deliberate sip of her water.

"Call the police," Corrie said. Her voice was calm, cold, and projected perfectly over the screaming crowd. "And while we wait, have Davis pull the security footage from the second-floor hallway camera."

Dean's heart leaped with a dark, vicious thrill. That camera? She had personally taken a pair of wire cutters to its power supply two days ago. There was absolutely no way it caught anything.

"The camera?" Dean yelled, her voice dripping with fake tears and real venom. "The camera in that hallway has been broken for two days! You knew that! You planned this in a blind spot, you sick, twisted girl!"

The crowd gasped. The narrative was set. Premeditated attempted murder.

George raised his right hand. His palm was open, his muscles trembling as he prepared to strike his eldest daughter across the face.

Corrie didn't flinch.

She calmly reached into the pocket of her deconstructed dress with her free hand. She pulled out her matte-black smartphone.

Her thumb swiped across the screen, bypassing the lock. She tapped an icon that looked like a jagged lightning bolt.

"Broken?" Corrie asked, her lips curling into a terrifying, razor-sharp smirk. "That's funny. Because my feed looks crystal clear."

She hit a single button on her screen.

Behind George, in the center of the ballroom, hung a massive, 100-inch LED screen that had been displaying the Warren Foundation logo all night.

The screen suddenly went black.

A loud, electronic chirp echoed through the room's surround-sound speakers.

The screen flared back to life.

It wasn't showing a logo. It was showing a high-definition, night-vision enhanced security feed. The timestamp in the corner read exactly two minutes ago.

The entire ballroom froze. George slowly turned his head to look at the screen.

The video played in absolute silence.

It showed Corrie standing perfectly still, holding her glass. It showed Kelly sprinting up the stairs, her face twisted in rage.

The crowd watched in breathless horror as the high-definition camera captured Kelly lunging forward. They saw Kelly's hands clamp onto Corrie's wrist. They saw Corrie freeze like a statue.

And then, they saw Kelly scream, let go of Corrie, and violently throw herself backward down the stairs.

Corrie hadn't moved a single muscle.

The video ended, and immediately looped back to the beginning, playing the damning evidence over and over again.

The silence in the ballroom was absolute. It was the silence of a vacuum.

Kelly, lying on the floor, stopped crying. The blood drained from her face so fast she looked like a corpse.

Dean stared at the massive screen. Her mouth hung open. A cold, paralyzing dread seized her heart, squeezing it until she couldn't breathe.

She had personally cut the wires to that camera two days ago. It was physically impossible for it to be recording.

Unless the girl standing at the top of the stairs wasn't just a rust-belt dropout.

Corrie looked down at Dean's terrified, pale face. Corrie's eyes were black voids.

The trap hadn't been set by Kelly. The trap had been set by Corrie. And they had walked right into it.
