Hook.

Laura and her boyfriend Carl were sitting in the car listening to the radio. This is what they did every Tuesday night. They went down the pub had a few beers and sat on the car and chatted and sang along to the radio. They did this on Tuesday's to celebrate the fact Monday was over. A song was just ending and the news starting.
"A serial killer has escaped from jail. He is nowhere to be found." The reporter was saying.
"He has a hook for a left hand."
"Gross!" exclaimed Laura.
The reporter was saying something about keeping a look out and informing the police on any leads.
Just then there was a scratching sound on the car door.
"Carllllll... What was that?!" Demanded Laura.
"This old heap is always creaking and squeaking. Don't worry about it."
The scratching came again.
"Let's go. Now!"
"Ok ok. Fine"
They drove of towards Laura's house. When they arrived home Laura jumped out of the car to see a hook swinging on her door handel before dropping to the floor and rolling down the drive.....
