Discarded Fiancée: The Ruthless Billionaire's Obsession

"My fiancé is cheating on me."

That was the first thing Jeannette said as she got into the car. She even skipped greeting her friend Eleanor.

Behind the wheel, Eleanor let out a gasp. "What?!" She snapped her head toward Jeannette, her face full of disbelief and anger.

Eleanor saw exhaustion in Jeannette's eyes-from the eighthour flight-along with an icy calm. She was now certain: Jeannette was not joking.

Jeannette held up her phone screen for Eleanor to see. It was a photo, apparently taken secretly-Devyn, Jeannette's fiancé, was kissing another woman passionately. What shocked Eleanor even more was that this woman was Jeannette's stepsister, Zara.

Eleanor cursed. She threw the car into drive and floored the gas pedal. The Range Rover merged onto the highway with violent speed. "That hypocritical, lying piece of trash! The Langley family parades him around like he's a saint. I'm going to kill him, Jeannette. I'm going to physically destroy him."

Jeannette's stomach twisted into a tight, painful knot, but she refused to let her hands shake. She pressed her thumbnail hard into the side of her index finger, grounding herself with the sharp sting of pain.

Jeannette said, staring blindly at the blurred taillights of the cars ahead, "I need a knife. The sharpest one I can find."

Eleanor glanced at her, a shiver running down her spine at the absolute ice in Jeannette's eyes.

The SUV plunged into the dark, underground parking garage of Eleanor's Back Bay penthouse. The sudden absence of light felt heavy. Jeannette unbuckled her seatbelt with a sharp click. Her movements were mechanical, precise. Like a soldier loading a weapon.

Minutes later, the private elevator opened directly into Eleanor's apartment. Jeannette kicked off her heels. She stepped barefoot onto the plush rug, completely ignoring the breathtaking night view of the Charles River through the floor-to-ceiling windows.

Eleanor walked straight to the liquor cabinet. She pulled out a bottle of vintage Macallan and poured two fingers of neat whiskey into heavy crystal glasses. She shoved one into Jeannette's hand, desperate to break the suffocating tension in the room.

Jeannette tipped her head back and swallowed the amber liquid in one gulp. The alcohol burned a fiery path down her throat, settling like hot coals in her stomach. It fueled the quiet rage pulsing in her veins.

"We send the photo to the press right now," Eleanor said, pacing the floor.

"No." Jeannette shook her head. She set the empty glass down with a thud. "A photo isn't enough. The Langley PR machine will spin it. They'll say it's photoshopped. They'll say it's an AI deepfake. I need more."

She pulled her laptop from her carry-on bag and flipped it open. The harsh blue light illuminated her pale face. Her fingers flew across the keyboard, pulling up the detailed asset list she had demanded from Devyn's accountant months ago under the guise of pre-nuptial planning.

"What are you looking for?" Eleanor asked, leaning over her shoulder.

"A blind spot," Jeannette murmured. Her eyes scanned lines of data until they locked onto a specific address. A private luxury apartment on the Upper East Side in Manhattan. Unregistered under the main Langley family trust.

Jeannette pointed at the screen. Then she pulled up the cheating photo on her phone and zoomed in on the background. "Look at the headboard. Look at the custom nightstand. It matches the interior designer's portfolio for this exact Manhattan address."

She reached into the hidden zipper of her wallet and pulled out a sleek, black keycard. She slapped it onto the glass coffee table. The plastic made a sharp smack.

"He gave me this six months ago to prove he had no secrets," Jeannette said, a bitter, hollow laugh escaping her lips. "He even forgot he gave it to me."

Eleanor stared at the card, her eyes widening. "Jeannette... what are you doing? And please tell me you're not about to pull that same crazy stunt you used to crash those billionaire yacht parties in Monaco. Thank God you're finally dropping that sweet fiancée act, but this is dangerous."

Jeannette didn't answer. She opened a new encrypted tab, navigating to a secure messaging network she hadn't used since her grandfather passed. She rapidly typed out a message to an old family fixer, someone who specialized in the grey areas of high society. She requested compact, powerful, and completely untraceable surveillance tools. Military-grade pinhole cameras. High-fidelity audio bugs.

Eleanor sucked in a sharp breath. "That's a felony. You're crossing into wiretapping laws."

"In the old money circles, the winner writes the laws," Jeannette said, her voice dropping to a dangerous whisper. "I need you to use your media contacts. Get me the security floor plan for the Langley charity gala next week."

Eleanor hesitated, chewing her bottom lip. "The security there is insane."

Jeannette turned her head. She locked eyes with her best friend. The intensity in her gaze was terrifying.

"Okay," Eleanor breathed out. "I'll get it."

Jeannette turned back to the screen. She booked a first-class ticket on the first flight out in the morning from Boston to New York. Departure was at dawn, giving her just enough time to mentally prepare for the infiltration.

"Sleep for one night," Eleanor begged. "You look like you're going to pass out."

Jeannette grabbed her empty whiskey glass and slammed it down on the table, the crystal ringing loudly. "The fire is burning right now, El. I'm not letting it go out."

About 30 minutes later, the doorbell chimed. The local courier.

Jeannette walked to the door. She signed the digital pad. Her hand didn't tremble even a fraction of an inch. She took the black package, ripped it open on the kitchen island, and expertly checked the battery packs and transmission signals of the tiny lenses.

She shoved the equipment into a nondescript black backpack. She stripped off her travel clothes and pulled on a pair of black leggings, a black hoodie, and a dark baseball cap.

Before she walked out the door, she stopped in front of the entryway mirror. She stared at the woman looking back at her-cold, exhausted, and lethal. She looked down at her left hand. She grabbed the five-carat diamond engagement ring, pulled it off her finger, and tossed it carelessly onto the shoe cabinet. It landed with a dull clink.

The heavy front door shut behind her. Jeannette stepped alone into the freezing Boston night.
