A Scanner Darkly
John W. Campbell Memorial Award: Best Novel nominee (1978).
Cops and criminals have always been interdependent, but no novel has explored that perverse symbiosis more powerfully than A Scanner Darkly. Bob Arctor is a dealer of the lethally addictive drug called Substance D. Fred is the police agent assigned to tail and eventually bust him. To do so, he has taken on the identity of a drug dealer named Bob Arctor. And since Substance D – which Arctor takes in mammoth doses – gradually splits the user's brain into two distinct, combative entities, Fred doesn't realize that he is narcing on himself.
Philip K. Dick
Philip Kindred Dick (1928–1982) was an American novelist and short story writer whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug use, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly.
