Tiny house of horrors

The storm hit fast. One minute you were driving down the highway, the next, a torrential downpour blinded you, forcing you off the road. You stumble through the darkness, lightning illuminating a dilapidated tiny house in the distance. Desperate for shelter, you approach cautiously… The door creaks open as you push, revealing a dimly lit interior. You step inside, unaware that this refuge is anything but safe. The door slams shut behind you, the lock clicking ominously. Trapped.  Are you alone? Or have you just stumbled into the home of the Bloomington serial killer?
