I have a protagonist who pretends to hunt ghosts, but is actually a fraud. He goes to purportedly haunted places, makes a show of searching around (EMF meter and all) and then assures his clients that the spirit(s) is/are gone. He believes that ghosts don't exist and supposes that he is actually hunting the "ghosts" inside people's minds. That's how he justifies what he is doing. Does all that sound plausible? If not, possible alterations? And why would the people he duped not contact him after he's left? Any concrete reason you can fabricate? If it's important: in the story, he would come across a real ghost. Thanks.
