Free my soul

A few years ago, it was discovered that torture was going on inside a manor. This was only discovered because the bodies of the murderers were found outside the manor.

No one had expected that 6 select souls of their victims, unable to pass on, had killed the murderers.
And that was pretty reasonable that no one did.

Years later, three preteens explore a manor that was recently made public area. Although everyone knows the happenings of horror movie cliches, it's still terrifying if you ever experience one.
