How did Fox Mulder become a believer?

In the spring of 1979, seventeen-year-old Fox Mulder has bigger problems than applying for college. Five years ago, his younger sister disappeared from their home and was never heard from again. Mulder blames himself, and his mother blames his father, who has retreated into his top-secret work for the State Department. In Fox's senior year, his dad has moved him to Washington, DC?away from his friends on Martha's Vineyard.

While Mulder doesn't mind the fresh start and not being known as "that kid with the missing sister," he's still obsessed with finding Samantha. So when a local boy turns up dead and another child is abducted, Mulder can't stop himself from getting involved. Could there be a link to his sister's case? As he uncovers the truth, Mulder and his friends find themselves on the trail of a serial killer.

Sucked into a world where conspiracies, the occult, and madness overlap, Fox Mulder starts to believe.
