Un oscuro scrutare

A Scanner Darkly is a science fiction novel by American writer Philip K. Dick, published in 1977. The semi-autobiographical story is set in a dystopian Orange County, California, in the then-future of June 1994, and includes an extensive portrayal of drug culture and drug use (both recreational and abusive). The novel is one of Dick's best-known works and served as the basis for a 2006 film of the same name, directed by Richard Linklater.
