The Billionaire's Accidental Mistress

"Are you sure about this, Freya? This one feels... too big."

The voice crackled slightly through the tiny earpiece Freya was adjusting, but the anxiety in it was perfectly clear. Lysander, her tech genius and reluctant partner, always sounded like a concerned older brother right before she walked into a lion's den.

Freya smiled, but the expression didn't touch her striking hazel-gold eyes. She was standing in the immaculate, marble-clad restroom of the grandiose Creed Tower, applying the final touch of a nude gloss to her lips. She didn't look like a woman about to commit a calculated professional seduction; she looked like quiet money, refined and slightly shy.

"Relax, Lys. It's just another bored husband needing a loyalty test," she murmured, her voice smooth and low, the 'Evelyn' voice. It was soft, a little breathy, hinting at vulnerability-the perfect lure for men who enjoyed feeling powerful and protective. "Besides, the fee Lara paid is triple our usual. We take the high-profile ones, remember? That's the brand."

Freya leaned closer to the mirror, assessing her reflection. Freya Lune was gone. In her place was Evelyn-a fictional art gallery consultant with a tragic backstory and impeccable taste.

Her dress was a masterpiece of subtle deception: a pale blue silk slip that clung just enough to hint at the lithe, dancer-like build beneath, but still managed to look innocent. She had chosen a style that whispered 'mistress' to a man looking for forbidden pleasure, but shouted 'respectable' to anyone else. Her long, auburn hair, usually sleek, was styled in soft, cascading waves tonight, adding to the illusion of fragility.

"The target is Theron Creed, Freya. The younger brother. Not the CEO. He runs the non-profit arm. He's supposed to be the good one," Lys muttered, still worried.

"Good ones cheat too, Lys. They just feel guiltier about it," Freya replied, clipping a small, diamond butterfly into her hair-her only real piece of jewelry tonight. "The client specifically hired me to test his loyalty. She's insecure, she wants proof one way or the other. It's simple market psychology. Now, run me through the perimeter one last time."

A moment of silence, then Lys's voice shifted into professional mode. "Okay. You're on the 65th floor, Creed Global Holdings annual philanthropic gala. Security is tight, but only focused on unauthorized access to the vaults. You're already cleared as a guest of the Valera party. The target, Theron, should be near the silent auction tables, avoiding the spotlight. I've sent the image and the floor plan again. Confirm receipt."

Freya glanced at her phone-a secure, disposable burner. She pulled up the image the client, Lara Creed, had provided. It was a poorly lit, slightly grainy candid shot of the target taken from a distance. The man was standing alone near a window, his posture slumped, the harsh shadows exaggerating the lines of exhaustion around his eyes. He looked weary, burdened, and isolated.

"Image received," Freya confirmed. "He looks exactly like the type who wants to be
