A person can get involved in an inexplicable story with a terrible ending anywhere. And whenever. On Earth, and underground, and even in deep space. In our days, and in the past, and in the future (which, hopefully, will still be different). You never know what an ordinary fishing trip or an innocent desire to have a “digger” picnic in old adits might turn out to be... Or you might not leave the house at all, you still won’t be able to escape fate - you’ll hear heavy footsteps outside the door and... "The footsteps fell silent. Right at the door. Mikhail took the pistol off the safety and raised the weapon to eye level. A second, two, three... Nothing happened. Then another sound was heard from behind the door... Like something soft fell from a small height... Or someone small softly jumped off... A cat, for example... A cat... Keys to the entrance... Gate control panel... Confident steps through the dark house straight to his room.. .Everything added up one to the other. It formed into a picture that the brain categorically did not want to acknowledge.”
