The blackout lasted only a few seconds, but it was enough to make Adam’s pulse race. When the lights came back on, the office was exactly as before, quiet, polished, and still. Yet something felt wrong. He turned slowly, scanning the room. The corridor beyond was empty. No movement, no sound. Only the low hum of the air conditioner returned, faint and steady. He let out a shaky breath and rubbed the back of his neck. Maybe he was imagining things. Maybe it was just the stress. But he couldn’t shake the feeling that someone had been there. Watching. He shut down his computer and decided to leave. As he walked toward the elevator, his phone buzzed again. Another message from Emily. Are you still at the office? He hesitated, then typed back.
