Be interesting to know if the power was just out only for HER apartment.
That really would be strange, and very suspicious.
Couldn't have been a major power fault in the building, as the elevator was still working.
It's bad if she suspects the building owner/landlord is cutting her apartment's electricity supply as a joke, as he is the one she should be contacting if there's a problem. But they've had issues before, so she can't do it ...so the only other choice is to investigate the power outage yourself.
Sounds like she was lead into a dangerous situation, even if the building owner wasn't responsible for her disappearance himself, he could've got someone to do the job.
MOO.
