In April 1943, four boys exploring Hagley Wood in England made a discovery
inside the hollow trunk of an ancient wych elm tree—a human skull.
The victim was never officially identified. She became known only as Bella, after
mysterious graffiti began appearing across Birmingham asking:
"Who put Bella down the Wych Elm?"
Who was Bella?
Who placed her body inside the tree?
Who wrote the graffiti?
More than 80 years later, this remains one of Britain's unsolved
mysteries.
In this true crime documentary, we examine the complete case—from the
discovery and police investigation to the strange graffiti, the leading theories, and the
unanswered questions that continue to fascinate historians and true crime enthusiasts
around the world.
