A girl lives in a house with her parents. There is a cellar door in the house, and her parents warn her to never, ever, open it because she's not ready to see what's behind it.
What is on the other side of the door that her parents don't want her to see?
The girl is locked in the cellar. Her parents are both crazed people who thought the best way to protect their daughter would be by locking her in the cellar since she was born. On the other side of the door is the rest of the house, and the outside world.
A dead body is found at the bottom of a multistory building. Seeing the position of the body, it is evident that the person jumped from one of the floors, committing suicide.
A homicide detective is called to look after the case. He goes to the first floor and walks in the room facing the direction in which the body was found.
He opens the window in that direction and flips a coin towards the floor. Then he goes to the second floor and repeats the process. He keeps on doing this until he reaches the last floor. Then, when he climbs down he tells the team that it is a murder not suicide.
How did he come to know that it was a murder?
None of the windows were left open. If the person jumped, who closed the window?
