Dolls house on the stairs, guarding the rooms above. Just a wooden box basically, denying access.

Now someone approaches, but a draft seems to blow from the painted doors, like someone breathing out.

A step up, high heels clunk on the wood. Impatient to pass, the figure still hesitates. Then, lights illuminate the windows in the dolls house!

She steps  back, trips, and falls on her bottom. She stands and looks up at the house, now flames are licking up the walls across the steps and up the stairwell.. A moaning starts..

Back in the office, Val watches the CCTV. That will stop you seeing my husband! She chuckles gleefully.
