My book of horror stories

Always look in the backseat...

A women was driving down the road in her car, when suddenly a man came behind her. He kept pipping his horn and waving his hands around whenever she looked at him. Eventually she pulled over, and the man came up to the window, she was being cautious and locked the car, rolling down the window half way. She asked him what's wrong and he pointed to her backseat. She didn't have time to react when she heard a laugh coming from behind. She turned around, meeting murderous eyes staring back at her. With one swift movement he'd stabbed the women in the head, making fall forward onto the staring wheel. The man ran back to his car, making sure he'd checked the backseat before getting in.
