Chapter 2 - The Art of the Counter-Strike

"Long night at the Henderson account?" Sienna’s voice was dangerously calm, cutting through the quiet foyer like a scalpel.
Derek froze, his hand still resting on the doorknob. A micro-expression of panic crossed his features before he plastered on his signature winning smile and walked into the kitchen, tossing his briefcase onto the floor with a heavy thud.
"Brutal, Sien," he groaned, leaning down to press a perfunctory kiss to the top of her head. He smelled faintly of expensive gin and a sweet, unfamiliar perfume that made her stomach turn. "They’re renegotiating the entire fiscal year. I swear, if I look at another spreadsheet, my eyes are going to bleed. You should have gone to sleep."
Sienna turned her head slowly, looking up at him with eyes as dead and clear as winter ice. "Did you eat?"
"Grabbed a protein bar in the car," Derek lied smoothly, walking over to the fridge and pulling out a bottle of water. He unscrewed the cap, his back to her. "You okay? You look pale."
"I found your jacket receipt," she said.
The plastic bottle crinkled violently in Derek’s grip. He didn't turn around immediately. For three agonizing seconds, the only sound in the kitchen was the hum of the refrigerator. When he finally spun back to face her, the mask was gone, replaced by a tight, defensive scowl.
"What receipt?"
Sienna slid the thermal slip across the marble counter. It stopped right by his elbow.
Derek stared at it. The blood drained from his face, leaving his skin a sickly, gray-green hue. For a second, he looked like a cornered animal, calculating escape routes. Then, anger—the universal weapon of the guilty—took over.
"You’re going through my pockets now?" he snapped, his voice rising in pitch. "Is that what we’re doing? You’re playing detective over a business dinner?"
"At Le Jardin?" Sienna raised an eyebrow, her voice deathly quiet. "Since when does the Henderson accounting team share chocolate lava cake for two at 8:30 on a Thursday night? Did you split the dessert with Greg from HR, Derek? Or did you feed it to the woman wearing the perfume currently lingering on your collar?"
Derek slammed the water bottle down, water splashing onto the counter. "You’re being paranoid! Clients like nice places! We had to wine and dine a prospective partner to close the loop on Henderson. Not everything is a conspiracy against you, Sienna!"
"Right," she murmured, standing up from her stool. She was not shouting. Her voice carried a terrifying weight that made Derek take an involuntary step back. "And the Cartier bracelet? Was that a corporate write-off too?"
Derek stiffened. The color rushed back to his face, but this time it was hot, furious crimson. "What are you talking about?"
"I found your little black book, Derek." Sienna reached behind her back and placed the small leather notebook flat on the counter, open to the page detailing the Grand Vista hotel stays. "You’re not just cheating. You’re sloppy. You left a paper trail that a high school intern could follow."
The silence that followed was suffocating. Derek looked at the book, then at his wife. The charming, infallible corporate climber melted away, revealing a desperate, trapped coward.
"Sien... baby, let me explain," he stammered, lunging forward to grab her hands. "It’s not what you think. It’s... it’s a mistake. A phase. Work stress, it’s been driving me crazy, I made a stupid error in judgment—"
"Don't touch me," Sienna whispered, her voice dropping to a register that made his skin crawl. She stepped back, her gaze burning into him. "You’re right about one thing. It is a mistake. The biggest mistake of your life. Because starting tomorrow morning, your life as you know it is over."
"What does that mean?" Derek demanded, panic finally cracking his facade wide open. "Sienna, don't do anything rash. We can talk about this! We can go to counseling!"

"Counseling?" Sienna let out a dry, humorless laugh that sounded like breaking glass. "You can’t counsel a corpse, Derek. And our marriage died the moment you paid for two glasses of champagne with our joint checking account."
She walked past him toward the stairs, leaving him standing alone in the harsh light of the kitchen, staring at the little black book like it was a ticking bomb.
