There's something weird going on deep in the London Underground. Down in the subterranean labyrinths of long abandoned tunnels, ventilation shafts and disused stations, strange creatures are engaged in pointless battles of stupidity in their dark hidden world. And the discovery of a stone table with amazing powers will only make things worse, as with staggering incompetence, the rival gangs fight to gain control of it. But who will be the victors? Which of them will gain control of the table? Will they have a clue what to do with it? And in the process, how much longer will they be able to keep their existence a secret? Could the world below ground, and the world above ground, be well on course for an unpredictable collision?
