Download or read book A Scanner Darkly written by Philip K. Dick and published by Del Rey. This book was released on 1977 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bob Arctor is a dealer of the lethally addictive drug Substance D. Fred is the police agent assigned to tail and eventually bust him. To do so, Fred takes on the identity of a drug dealer named Bob Arctor. And since Substance D--which Arctor takes in massive doses--gradually splits the user's brain into two distinct, combative entities, Fred doesn't realize he is narcing on himself. Caustically funny, eerily accurate in its depiction of junkies, scam artists, and the walking brain-dead, Philip K. Dick's industrial-grade stress test of identity is as unnerving as it is enthralling.
