In the US, there’s one urban legend everyone knows, although I don’t know it’s the scariest.
Most of us call it simply ‘The Hook’. It involves a young couple parked somewhere isolated to make out, even though there’s an insane, be-hooked murderer on the loose. The girl keeps hearing a light scratching at the door, and is so insistent that the guy gives up on said makeout and throws the car into gear. The couple arrives home safely, but opens the girl’s door to find a bloody hook dangling from the door handle.
Listen, I suspect this story is not actually rooted in reality but is a condemnation of pre-marital sex slyly passed down by some dad somewhere (Iowa maybe?). This doesn’t make the study of this and other crazy stories any less fun, so I visited the giant wormhole that is AmericanFolklore.net. If you go, be prepared to lose hours of your life to reading stories with titles like Bloody Mary, Bleeding Sink and Burnt Church.
But I still don’t think any other story is quite as popular as The Hook. What’s the UK equivalent?
