A millennium into the future, two advances have altered the course of human history: the colonization of the galaxy and the creation of the positronic brain. Isaac Asimov's Robot novels chronicle the unlikely partnership between a New York City detective and a humanoid robot who must learn to work together. Like most people left behind on an over-populated Earth, New York City police detective Elijah Baley has little love for either the arrogant Spacers or their robotic companions. But when a prominent Spacer is murdered under mysterious circumstances, Baley is ordered to the Outer Worlds to help track down the killer. Then he learns that he has been assigned a partner: R. Daneel Olivaw. Worse, the R stands for "robot" - and his positronic partner is made in the image and likeness of the murder victim!
