The Martian Inca

Synopsis - The Mars Probe has crashed – A triumph of Soviet technology, the first two way interplanetary probe performed brilliantly until the final stage of its return. Then something went wrong: rather than following its programmed course to a soft landing in its country of origin, the probe crashed in the Peruvian Andes. Now a weird infection beyond the understanding of medical science has wiped out an entire village – except for one man, who, alone and undiscovered by the medics, survives. He has awakened to find himself become his own ancestor, and a god. Suddenly the flames of an Indian revolution are spreading in South America; he is the Martian Inca.
