Dick is renown for his dark, paranoid even delusional visions of the future. But 'A Scanner Darkly' is probably the most accomplished example of this. The story traces the ever declining life of undercover Narc. Bob Arctor, a man so beyond redemption he has given up his family to become a full-time professional police informant. As the story unfolds the lines between Arctor's lives become more and more blurred, a burned out addict on the one hand an undercover agent on the other. All seems well until the mysterious 'substance D' the 'D' being for 'Death' hits the streets and Arctor is assigned to find out what it is and where it comes from.
The assured and confident prose is a sign of this being a work by an author in his prime and very much on home soil, Dick's own life was in a constant state of flux due to his own drug abuse and this gives this novel the touch of realism lacking in so many other drug culture novels.
'A Scanner Darkly' is simply a wonderful look inside addiction, insanity and paranoia. A must for any Phil Dick fan, a great start for any potential converts.
