Darkness Cries

This house is haunted... A woman asks for my help because she thinks her rental house is haunted. No problem. I deal with ghosts all the time. It looks like a quick and easy fix. But when are my cases ever easy? This one takes a turn to the nasty right off the bat because it's not just a ghost haunting the house. And of course what lurks in the darkness is powerful enough to kill me. But if it were an easy case, I wouldn't have a reason to talk about it. I only hope I can live long enough to finish the story...
