The Observer on the Windowsill

Marcus's cat watched from the windowsill, those amber eyes tracking everything. The animal had been Sarah's gift three years ago, back when they were still playing padel every Tuesday and Thursday evenings at the club, back when Marcus believed their friendship was built on something solid.

Now Sarah sat in his living room, wine glass in hand, while lightning fractured the sky outside—appropriate weather for what she'd just revealed.

"Corporate hired me," she said, not looking at him. "They needed someone on the inside. Someone who could get close to the lead architect without raising suspicion."

Marcus felt the room tilt. Not a lover's quarrel, not a misunderstanding between friends. She was a corporate spy, and he'd been her assignment for eight months.

The cat meowed then—a sound like tearing paper—and jumped to the floor, circling Sarah's ankles with aggressive affection. Traitor, Marcus thought. Even the animal had been turned against him.

"I told them I couldn't do it," Sarah said, setting down the glass. "Last week. That's why I'm here. That's why I'm telling you now."

Another flash of lightning illuminated her face—so familiar, so completely unreadable. Marcus wanted to believe her. Wanted to believe that the Tuesday matches, the after-work drinks, the long late-night conversations about burnout and ambition and the hollow ache of thirty-something loneliness had all been real on her side too.

But she'd taken the job in the first place. She'd accepted money to infiltrate his life, to map his vulnerabilities, to report back on the project that represented everything he'd worked toward for a decade.

"Did you sleep with me because they asked you to?" he asked, and his voice sounded like someone else's voice—someone harder, someone who learned too late how to weaponize his own heart.

Sarah finally looked at him. "Marcus."

The cat scratched at the door, wanting out. Neither of them moved to open it.
