The Mistress Tortured the Pregnant Wife on the Marble Foyer, Unaware the Husband Was Watching Through a High-Definition Security Camera

Chapter 1: The Gilded Trap
The Sterling Manor was a masterpiece of cold, detached luxury. The foyer, with its soaring twenty-foot ceilings and polished Carrara marble, usually felt like a palace; tonight, it felt like a surgical theater for psychological warfare. Julian Sterling, the head of the Sterling family, was out of the country for an emergency board meeting, leaving the field open for the woman who had been lurking in the shadows of his marriage for months: Seraphina.
Seraphina was a woman of expensive tastes and even more expensive malice. She had maneuvered herself into the household as a "business associate," but her true goal was the total erasure of Julian’s wife, Clara.
Clara, seven months pregnant and visibly exhausted, lay on the cold, unforgiving stone of the floor. She had tried to leave, to take her things and find a sanctuary away from Seraphina’s constant, poisonous harassment. But Seraphina had stopped her in the foyer, her face twisted into a mask of cruel delight.
"You should have left," Seraphina commanded, her voice ringing off the marble like a strike. She was dressed in a stunning burgundy silk dress that flowed over her lithe frame, a stark contrast to the simple, humble beige maternity dress Clara wore.
"Please, Seraphina," Clara whispered, her hand instinctively shielding her stomach. "I’m going. I’m just taking my things. Please, just let me go."

"Don't say another word," Seraphina hissed. She stepped forward, her movements predatory. With a calculated, agonizing motion, she pressed the sharp, needle-like heel of her designer shoe against Clara’s cheek, forcing her head to turn toward the cold floor. "Julian doesn't want you. He’s just waiting for the right moment to get rid of you. You’re a liability, a mess of hormones and poverty. I’m doing him a favor by cleaning you out."
Seraphina was blinded by her own toxic ego. She had spent months perfecting a narrative where Clara was "unstable" and "abusive." She was absolutely confident that when Julian returned, he would look at Seraphina’s practiced, dramatic tears and believe every word of her well-rehearsed lies.
