The 80-year-old Mystery of the Skeleton Found in a Wych Elm (BBC)

On the 18th of April, 1943, four schoolboys were out poaching for birds eggs in Hagley Wood, England. They came across a wych elm tree and one of the boys hoisted himself up in amongst the branches when something untoward instantly caught his eye. Nestled inside the hollow trunk of the tree was a human skull.

Local police would later uncover an almost complete skeleton entombed within the tree, and 80 years later the mystery still rumbles on: 'Who put Bella down the wych elm?'
