In the winter of 1931, on a remote stretch of Otterburn Moor, Northumberland, England, a tragedy shook the local community. Evelyn Foster, a young taxi driver who was well known in her community, was found badly burned next to her charred car. Before she died, Evelyn had testified that she was attacked by a male passenger who then burned her alive. Despite the investigation, the case remains an unsolved mystery to this day.
