We're back with another Spooky Season episode and this time we're going international!

At the height of the Second World War, four young boys in the U.K. went into the woods looking for bird's eggs. Instead, they were met with an unforgettable and terrifying discovery. A human skull was hidden inside the hollow trunk of a wych elm. To this day, the woman killed and placed inside the tree has never been identified. Megan walks us through the details of the case and the dozens of theories that have been spun over the last eight decades.
