Who is Claire Swanson from The House Next Door and what is their importance?

Claire Swanson is Colquitt's best friend. She lives two doors down from the haunted house. Claire is the one who finds Pie and calls for help when Pie miscarries her baby. Claire begins to believe the house is haunted when her chaste son has sex with his girlfriend in the house and the girl becomes pregnant. Claire believes this is an act of revenge by the house because Claire tried to interfere in the house's plans. Claire believes the house attacked her son instead of herself because it knew that the strike on the son would be more painful to Claire. After this experience, Claire begins looking for a new house to move into. After the Greenes' murder-suicide, Claire and her family move the next day. Although Colquitt tries to get Claire to help Colquitt and Walter spread the story about the house, Claire refuses to do so because she is so afraid of what the house might do to her or her family.
