Something has gone very seriously wrong with Tik-Tok's "asimov circuits". They should keep him on the straight and narrow, following Asimov's First Law of Robotics: "A robot shall not injure a human being, or through inaction allow a human being to come to harm". But they don't.
While maintaining the outward appearance of a mild-mannered robot, albeit one with artistic tendencies and sympathy for the robot rights movement, Tik-Tok's real agenda is murderously different. The chronicle of the rise of one completely amoral robot and his dealings with an assortment of deranged and maniacal humans is the showcase for the satirical genius of John Sladek
