Danny Robins and the team unpack a terrifying mystery that has remained unsolved for almost 200 years - Spring-heeled Jack.

The demonic character stalked the streets of Victorian England at night, reportedly slashing his victims with sharp claws, breathing blue-white fire, and evading the police by making impossible leaps over rooftops.

But was he a real person, a supernatural entity, or the product of mass hysteria?
