Anyway a bit of a long one
A woman released from prison doing a sentence for murder. She finds a man to settle down with and he moves in the her house. Every event the wife would go down in the basement for 2 hours and then come back out and lock the door.
To prove his trust he is asked not to go into the basement ever and if he did she would know. For a while the man proves faithful but when people started to go missing he could help but feel something was wrong.
Knowing his wife was at work he decided to take a look, he found a key on top of the door ledge and unlocked the door, the room was pitch black and he couldn’t find a light switch. In front of him he felt a bulb that was half unscrewed, he screwed it back in and was horrified to see dead bodies everywhere. Then he heard his wife coming home, he quick unscrewed the light, locked the door and placed the key in the exact same spot so his wife didn’t know it had been moved.
He quickly sat down in the living room and started watching TV.
The wife came in went straight down into the basement, came back up and told her husband she knew he’d been down in the basement.
How did she know?
