The Visitor

Tasked by the Federation of Planets to determine if Earthlings present a threat as they venture into space, Tak, an alien anthropologist, leaves her starship orbiting Earth and takes a shuttle to Kansas. Intending to study humans in the United States-as she has learned no Earth language but English-she is detected while descending through the atmosphere and only evades capture by fleeing to Europe, where she lands in Poland. There, she meets an international arms merchant, Baron Von Limbach, who becomes her guide. She studies "typical" human behavior by accompanying the baron as he fulfills his latest assignment-to get the Dalai Lama back into Tibet. His method of halting the communist takeover of Tibet is to create a race-specific Ebola that will only attack Han Chinese, giving Tak a prime example of how barbaric humans can be. However, the CIA and US military are aware of Tak's presence on Earth and are determined to capture her. And if she is unable to complete her mission and return to her starship-her captain will destroy every living thing on Earth.
