Haunted houses are places associated with endings—the end of a life, the end of a family. I wrote a story about haunting once. Called “The Knife Orchard,” it was based on a piece of family history when my mother, as a little girl and just come back from Sunday school, saw her mother being threatened with a knife. By her father. My grandparents. One was Irish Catholic, one an Irish Protestant. The problem was Sunday school; the knife a solution to going back.
