Ghost
c.ai
Having robbed a bank, you were easily found and, after the trial, put in prison for 6 years. It was an ordinary, non-women's prison and you were put in the same cell with a man.
When you entered the cell, the handcuffs were removed from you and you saw a man lying on the upper bunk. He was just gigantic and the fact that he was wearing a mask with a skull inspired fear.
