Substitute Marriage: The Billionaire's Hidden Queen

Cassie stepped onto the stone stairs. Her heels struck the granite with a sharp, heavy rhythm.

She reached the top and pressed her finger hard against the brass doorbell.

The melodic chime echoed through the thick wooden door. A few seconds later, it swung open.

A young maid stood in the doorway. Her eyes landed on Cassie's scarred face. The girl gasped loudly, stumbling backward, hands flying up to cover her mouth.

Cassie didn't blink. She walked straight past the terrified girl into the grand foyer.

Her heels sank into the expensive Persian rug, muting her footsteps. She turned her head, locking onto the center of the living room.

Kathleen Gilmore sat on the plush sofa, elegantly sipping from a porcelain teacup. A thin woman with severe cheekbones and carefully styled blonde hair, she looked every inch the wealthy matriarch.

Kathleen lowered the cup and looked up. When she saw Cassie standing there in a custom designer dress, looking entirely unbroken, her eyes widened. The teacup slammed down onto the saucer with a loud clatter.

Kailee, Cassie's adoptive sister, came running down the curved staircase. Dark-haired, sharp-featured, and wearing a silk robe that probably cost more than most people's monthly rent. She stopped dead. Her eyes darted over Cassie's expensive clothes. Her face twisted into pure jealousy.

Kathleen quickly recovered, forcing a sickeningly sweet smile onto her face. She stood.

"Cassie, darling!" Kathleen cooed, walking forward with arms outstretched.

Cassie shifted her weight and turned her shoulder, smoothly dodging the touch.

Kathleen's hands grasped empty air. Her smile faltered. She masked her annoyance with fake concern.

"Did Mr. Frederick hurt you?" Kathleen asked, her voice dripping with venomous hope. "We heard he has... violent tendencies."

Cassie let out a short, cold laugh. "Disappointed I'm not dead?"

She walked past Kathleen and sat down in the single leather armchair. She crossed her legs, posture relaxed but dominant. She had completely taken control of the room.

Kathleen's fake smile vanished. Her face hardened.

"I want my trust fund," Cassie stated. Flat, hard, no room for negotiation.

The silence stretched thick and suffocating.

Kailee shrieked. She stomped across the room, stopping right in front of Cassie, pointing a manicured finger at her face.

"You ugly freak! You don't get a dime!" Kailee screamed, her face turning red.

Cassie looked up at Kailee's trembling finger. Her eyes were dead and cold.

"Screaming won't change the law, Kailee. It just makes you look desperate," Cassie said softly.

Kailee's entire body shook with rage.

Kathleen stepped forward, pressing a hand to her chest, eyes filling with fake tears. "Cassie, how can you do this? After everything we've done for you? We raised you!"

Cassie's stomach churned. She unclasped her designer handbag.

She pulled out a thick stack of documents and tossed them onto the glass coffee table. The heavy paper slapped against the glass.

"Evidence of the Gilmore family embezzling from my biological parents' estate," Cassie said.

Kathleen looked down at the papers. The blood drained from her face, leaving her skin a sickly pale gray.

Kailee lunged forward. She grabbed the stack and ripped it apart. She tore the papers again and again, throwing the shredded pieces into the air. White confetti rained down over the coffee table.

Cassie sat perfectly still, watching like she was observing a pathetic circus animal.

"The digital backups are already with my lawyers," Cassie said, her voice cutting through the sound of tearing paper.

Kathleen's knees buckled. She collapsed heavily onto the sofa, breathing shallow.

The heavy oak doors of the study burst open. Josephus Gilmore marched out. A thick-set man with a flushed face and thinning gray hair, he radiated the arrogance of someone who'd never been challenged in his own house.

He took one look at the shredded paper and Kathleen's pale face, and his chest puffed out with fury.

He stomped toward Cassie, heavy footsteps shaking the floorboards.

"Get out of my house and go back to the asylum!" Josephus roared. Spittle flew from his lips.

Cassie gripped the armrests and pushed herself up to stand.

She stared directly into her adoptive father's eyes. The raw, unfiltered hatred in her gaze was so intense that Josephus actually stopped walking.

Kailee saw her father hesitate and immediately stepped to his side.

"Dad, she's trying to steal our money! She threatened Mom!" Kailee whined.

The hesitation in Josephus's eyes vanished, replaced by blinding rage.

He pointed a thick finger at Cassie's scarred cheek. "You are a disgrace to this family! A deformed, ungrateful parasite!"

The vicious words hit Cassie's ears, but her heart stayed numb. She'd heard worse.

"Transfer the funds by noon, or I will see you in federal court," Cassie said, icy and resolute.

Josephus's face turned a dangerous shade of purple. Veins bulged on his neck.

Kathleen sat on the sofa, dabbing her dry eyes with a tissue, watching the chaos unfold. Cassie caught the calculated gleam in her stepmother's eyes and felt fresh disgust.

"You think Frederick cares about you?" Kailee sneered, stepping closer. "He'll throw you out the second he gets bored of your ugly face! You have no one!"

Cassie didn't waste another word. She reached into her bag, pulled out her phone, and tapped 911.

Kailee saw the numbers on the screen. Her eyes widened in panic. Her last shred of sanity snapped.

Kailee lunged forward.

Cassie's muscles instantly coiled. She dropped her center of gravity.

Kailee raised her right hand high. The massive diamond engagement ring on her finger caught the light. She swung her hand down, aiming directly for Cassie's scarred cheek.

Cassie's left hand shot up.

Her fingers clamped hard around Kailee's wrist, stopping the slap dead in mid-air. Kailee's shoulder jerked forward. She struggled, but Cassie's grip held like a steel vice.

Cassie pulled her right arm back.

She swung forward with brutal force. Her palm connected with Kailee's cheek.

The sharp, explosive crack of the slap echoed off the high ceiling.

The blow spun Kailee around. Her high heels twisted under her weight. She crashed hard onto the hardwood floor.

Kailee clutched her rapidly swelling red cheek. A high-pitched, agonizing scream ripped from her throat.
