The Man Who Japed by Philip K Dick
The Man Who Japed is Dick's mesmerizing and terrifying tale of a society so eager for order that it will sacrifice anything, including its freedom. Newer York is a post-holocaust city governed by the laws of an oppressively rigid morality. Highly mobile and miniature robots monitor the behavior of every citizen, and the slightest transgression can spell personal doom. Allen Purcell is one of the few people who has the capacity to literally change the way of the world, and once he's offered a high-profile job that acts as guardian of public ethics, he sets out to do precisely that. But first he must deal with the head in his closet.
