Mulder and Scully are called out on an investigation involving a supposedly haunted house with a murderous ghost. They also find out a few other things (unrelated to the case) while they are there.
This one's a brief Mulder/other, resulting in some intense Scully jealousy. Don't worry, it ends as it should ;-). I'm still excited that I got to go on a paranormal investigation last night, complete with EMF Meters and heat and Kinect cameras and everything, so I figured a ghost hunting fic was in order. Unfortunately my experience didn't end up NC-17 rated though...
