Plot Summary
The book's central crime is a murder, which takes place before the novel opens. (This is an Asimovian trademark, which he attributed to his own squeamishness and John Campbell's advice of beginning as late in the story as possible.) Roj Nemmenuh Sarton, a Spacer Ambassador, lives in Spacetown, the Spacer outpost just outside New York City. For some time, he has tried to convince the Earth government to loosen its anti-robot restrictions. One morning, he is discovered outside his home, his chest imploded by an energy blaster. The New York police commissioner charges Elijah with finding the murderer. Elijah must work with a Spacer partner, a highly advanced robot named R. Daneel Olivaw who is visually identical to a human, even though Elijah, like many Earth residents, has a low opinion of robots. Together, they search for the murderer and try to avert an interstellar diplomatic incident.
One interesting aspect of the book is the contrast between Elijah, the human detective, and Daneel, the humanoid robot. Asimov uses the "mechanical" robot to inquire about human nature. When confronting a "Medievalist" who fears that robots will overcome humankind, Elijah argues that robots are inherently deficient. Being precision-engineered calculating machines, they can have no appreciation of art, beauty, or God; robots can understand only concepts expressible in mathematics. Nevertheless, in the concluding scene, R. Daneel exhibits a sense of morality. He argues that the captured murderer be treated leniently, telling his human companions that he now realizes the destruction of evil is less desirable than the conversion of evil into good. Quoting the Pericope Adulteræ, Daneel tells the murderer, "Go, and sin no more!"

Famous quotes containing the words plot and/or summary:
“The plot was most interesting. It belonged to no particular age, people, or country, and was perhaps the more delightful on that account, as nobody’s previous information could afford the remotest glimmering of what would ever come of it.”
—Charles Dickens (1812–1870)
“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
—George Gordon Noel Byron (1788–1824)
