The Big Grey Man is thought to lurk around Mount Ben MacDui in Scotland, creeping out any hikers who dare visit. But is the lanky ghoul real or is it all just tricks of the mountain? Athena and Tiernan bring you the evidence on grey giants and windy sounds, so that you, our Chief Detectives can solve the case.
