Philip K. Dick was one of the masters of science fiction, and his short stories consistently broke new ground. His work has provided the inspiration for many successful films, including Bladerunner, Minority Report, Paycheck and many more. In the overcrowded world and cramped space colonies of the late twenty-first century, tedium can be endured through the use of the drug Can-D, which enables the user to inhabit a shared illusory world. But when industrialist Palmer Eldritch returns from an interstellar trip, he brings with him a new drug, Chew-Z, which is far more potent than Can-D. But could the permanent state of drugged illusion it induces be part of something much more sinister?
