Sophia Cloud returned to her room alone, her heart filled with unease.
Despite the lateness of the hour, she felt no urge to sleep; the more she thought about it, the odder it seemed. She finally got up, drove her car to the building where Christopher Lewis had encountered trouble before.
The security guard on duty had changed, but as soon as Sophia mentioned the incident of that day, he remembered immediately and showed her the surveillance footage.
"Miss Cloud, all the surveillance from that day is here. It's from the entire day for this building. Normally, there would be cameras on every floor, but, coincidentally, the community was undergoing renovations that day and had to temporarily cut the power. That's why it's like this," explained the guard.
Sophia frowned, puzzled. What did he mean?
