During the early 1970s an international team noticed, while x-raying a group of royal mummies at the Cairo National Museum, some extremely unexpected physiological details among several of them. Separate DNA data collected in the early 1970s but not discovered or tested until two decades later, the chromosomal evidence proved to be equally disquieting. When taken together, they argued for the introduction of a unique genetic anomaly into the human genome during the Egyptian late Eighteenth Dynasty; the source was extraterrestrial. How does an international scientific effort resolved the situation by using a most unusual means for prosecuting a most unscrupulous task, time travel and murder?
