A strange race of people beneath London...

In the latest episode of THE SATURDAY STRANGENESS Neil Arnold looks into the legend pertaining to a race of subterranean dwellers inhabiting the deserted railway tracks, sewers and tunnels of London. Do beings, known as Troglodytes, feed off the food we throw away, and as some rumours suggest, also live off the occasional drunk tramp or two ? Do such primal people have their own language, evade human contact and exist in the world below one of the world's busiest cities ?
