The Last Pool at the Vertigo

The rooftop pool of the Vertigo Hotel had become my sanctuary since the divorce. Forty-fifth floor, city lights bleeding into the chlorine blue at 3 AM. I'd bear witness to the skyline alone, nursing a scotch I couldn't taste anymore, the numbness spreading from my tongue to my chest.

That's when I saw her — same spot every night, three weeks running. She moved like someone who knew how to disappear in plain sight. Not a swimmer. A watcher. My years in corporate security had trained my gut to recognize the posture, the way her eyes tracked the penthouse windows above rather than the water below. A spy, or close enough that the distinction didn't matter.

"Vitamin D deficiency," she said one night, sliding onto the adjacent chaise without asking. "That's why you're here. The lights. Your body thinks it's the sun."

I laughed, startled by the accuracy. "You sound like my ex-wife."

"I sound like someone who's been watching you longer than you've been watching me." She passed me a bottle of pills — not vitamins. Industrial-grade sedatives. "Gregor in 4B has a meeting at dawn. Important people. You're going to sleep through it."

The shock must have shown. "Who are you?"

"Someone who knows you used to be the person people hired to bear witness to things they weren't supposed to see." She stood, her silhouette cutting against the ambient glow. "Your vitamin pills have been replaced for weeks. You're already halfway to dreamland."

The last thing I registered before darkness took me was her diving into the pool — a single perfect ripple, gone as quickly as she'd appeared. The sedative hit like a freight train, and somewhere between consciousness and whatever came next, I understood: I hadn't been the one watching. I'd been the one being watched all along.
