… kills the tenants.
Many many years ago when I was about 6 (now over 50) I sneaked and watch a movie after being put to bed. I should not have been watching this movie as I think it was responsible for my claustrophobia. I can’t remember a lot about it except for the fact that a guy rents out a flat but hides under the floorboards and murders the occupants. At the end of the movie he is still under the floorboards when a new couple comes to view the flat. They move a wardrobe and unknowingly trap the guy under the floorboards. I just remember him being trapped in a small space screaming for help.
