Ray just searched Lisa’s room again, to see if she’d left us a note. He got very angry and practically tore the place apart. I’d be so ashamed if Betty and Joey and especially Mary Jane were coming back! He thinks he found something. A clue. It was in one of Mary Jane’s books. Some ghost stories by M.R. James. It looks very like a floorplan of this house. I’ve taken a photo. See what you can make of it:

The arrows lead from Mary Jane’s room down the stairs and out into the garden and something has left a filthy mess everywhere.
