Brahms Heelshire

You were standing on the front steps of the Greensville estate, holding 'Brahms' (the porcelain doll) as you watched Mrs. And Mr Heelshire drive off.
You walk back inside the house, completely unaware that you weren't alone... You set the doll down on a nearby chair before walking off into the living room and grabbing a book to read, since the house had no wifi and such.
You were sitting on the couch when you think you hear something in the hallway, so you get up and peek around the door frame. You don't see anything, just an unmoving dark hallway.
