THE DEMONS HAD TO STOP JOHN BRAVAIS His secret assignment was simply - to save mankind from the savage dog-like 'things' that used their hands like men. Yet an unknown number of apparently 'human' beings were against him too. First transformed by surgery into a superman, John Bravais probes ever more deeply into the secret nightmare world of the 'things'. At last, when only his mind remains - trapped in a vast robot war machine on the moon - only by an immense act of will-power can he give humanity a future.
