In the manner of Lewis Carroll's Alice, Richard Stanley disappears down a series of holes in the ground to investigate the subterranean world of tunnels, caverns and conduits that thread their way across the country, unseen beneath our feet.
In this final programme he invokes the aid of Nigel Pennick, chronicler of subterranean symbols, to delve deep into devilry, legends and lore.
