Who are these terrifying black-eyed ghost children, and why are they on the newspaper front pages all of a sudden?
It started on Sunday when the Birmingham Mail reported on "paranormal investigator" Lee Brickley's attempts to investigate sightings of black-eyed children at a beauty spot in Cannock, Staffordshire.
The Birmingham Mail then went one step further and joined Brickley on his "nightly vigil" to catch a "glimpse of the unkempt anaemic infant" on Cannock Chase.
The report said says that there have been sightings of Slender Man – a bogeyman invented by people on online forums – as well as a creature Brickley refers to as The Pig Man.
Then the Daily Star covered the chilling tale on Tuesday with a front-page story based on Brickley's testimony.
The paper followed up on Wednesday with this front page about a pub in Cannock that's haunted by various scary ghosts including a black-eyed child apparition.
And today the trilogy of bonkers Star front pages is complete, with a tale of how sightings are increasing around the world.
Other papers and broadcast stations covered the story this week. But where does this story actually come from? Brickley wrote a blog post last year about his auntie's sighting, which was then included in this book.
Brickley contacted us to say that – despite the Birmingham Mail's story – the chemical leak angle was entirely invented by the press and wasn't a theory that came from him.
However, the genesis of the black-eyed child myth appears to predate Brickley's blog post and book and to have originally emerged in a story posted by Brian Bethel, from Abeline, Texas, on a ghost-related online mailing list in 1998.
There is an entry on "black-eyed people" on the Creepypasta wiki, a directory of scary stories that originate online.
Getting images of the ghost kids is difficult – mainly because they are entirely fictional – so newspapers have made do with images like the one on the left, which is a crudely edited version of a creative commons image.
Either that or people take stills from the 2013 film Sunshine Girl and the Hunt for Black Eyed Kids, which was funded with a $9,500 Kickstarter campaign.
So, urban myth? Mass hallucination? Ancient bloodthirsty ritual? Or just a bunch of stuff that people have made up on the internet?
Or how about a fun spooky ghost story in the run-up to Halloween that gets readers excited and freaked out in equal measure? In any case, it seems the black-eyed children myth is one borne of internet culture rather than ancient folklore.
And it's all too easy to be misquoted when you write a book about supernatural events.
