Kalki
Gore Vidal
 James J. Kelly, a former soldier in the American military, finds out that the American and Soviet governments are about to conduct tests of a new kind of neutron bomb called the model b or the nC, which will kill every living thing on the planet, leaving it uninhabitable for centuries. The American generals know the cataclysmic effects of conducting these tests but they acquiesce to the tests anyway, ignoring a report provided to the National Security Council which predicts the end of the world if six or more nCs are simultaneously exploded. Mistakenly assured that the Soviets would not explode reciprocating nCs, the generals are unwittingly about to destroy the whole world. James J. Kelly decides to save the human race through an elaborate religious hoax, declaring himself to be Kalki and announcing the end of the world. His secret plan is to kill off everyone in the world except for himself and his wife Lakshmi. These two would then be the last living human couple on the planet. They would be the Adam and Eve to a new human race, giving birth to three sons and six daughters over the next twelve years, who would then intermarry and in about two centuries, the world would be fairly well populated again. In addition to himself and his wife, Kalki decides to bring along three more people to his new world, teachers called Perfect Masters, chosen for their knowledge and the fact that they are all sterile. These three people will teach various fields of science to the new race. Teddy Ottinger will teach engineering, Geraldine O'Connor biology and genetics, and Dr. Giles Lowell medicine. Kalki's wife Lakshmi is herself a physicist, and Kalki is a chemical engineer. Shockingly, Kalki succeeds in carrying out his insane plan and the entire world dies, leaving behind only Kalki, his wife Lakshmi and the three other Perfect Masters. However, Kalki's plans go awry when Lakshmi miscarries the first baby girl and it is learnt that Lakshmi is incapable of having children with Kalki. At this point, the only other male in the group, Dr. Lowell, announces that he never had a vasectomy and is the only one now with whom Lakshmi can conceive a child. It had been his plan all along to be the one to father the new human race with Lakshmi, whom he claims to be in love with. When Dr. Lowell admits his treachery, Kalki kills him. The story ends with a bleak postscript from Kelly/Kalki, forty three years after the apocalyptic plague. In the interim period, Teddy died twenty seven years after the plague and Geraldine (Teddy's lover and Kalki's second consort) died, as has Lakshmi. Kalki has become the last human alive, and with his death, the human species will become extinct. It is implied that simians will inherit the post-apocalyptic world.
