The old man's head snapped toward her, his brows furrowed. "What?"
She pointed at the monitor. "The camera in the east passage. It just flickered."
Rei quickly focused on the feed, zooming in on the dimly lit corridor. The camera flickered again, and this time, a faint shadow moved at the edge of the frame. It was brief—no more than a split second—but it was enough to make her stomach drop.
"There's someone there," she said, her voice rising.
The old man leaned forward, his eyes narrowing. "Zoom in," he ordered, his tone sharp.
Rei obeyed, adjusting the feed until the shadowy corner filled the screen. Her heart pounded as the flicker stopped, leaving the passage bathed in a heavy, unnatural stillness. She scanned the area frantically, but the figure was gone.
