I'm writing a haunted-house story set in the late 1890s in England. One of the characters is the local vicar. He's a skeptic about all this supernatural woogy stuff at first, but pretty rapidly becomes convinced that HOLY SHIT GHOSTS.
What would he do? Or, rather, would there be some kind of Church procedure he would follow? Wiki talks about an exorcism procedure, and Googling has revealed "The Exeter Report," circa 1974, that talks about cleansing a house, but I can't find any earlier records.
