En ce début de treizième millénaire, l'Empire n'a jamais été aussi puissant, aussi étendu à travers toute la galaxie. C'est dans sa capitale, Trantor, que l'éminent savant Hari Seldon invente la psychohistoire, une science nouvelle permettant de prédire l'avenir. Grâce à elle, Seldon prévoit l'effondrement de l'Empire d'ici cinq siècles, suivi d'une ère de ténèbres de trente mille ans. Réduire cette période à mille ans est peut-être possible, à condition de mener à terme son projet : la Fondation.

A millennium into the future, two advancements have altered the course of human history: the colonization of the Galaxy and the creation of the positronic brain. On the beautiful Outer World planet of Solaria, a handful of human colonists lead a hermit-like existence, their every need attended to by their faithful robot servants. To this strange and provocative planet comes Detective Elijah Baley, sent from the streets of New York with his positronic partner, the robot R. Daneel Olivaw, to solve an incredible murder that has rocked Solaria to its foundations.

In the vast, domed cities of Earth, artificial intelligence is strictly controlled; in the distant Outer Worlds, colonists and robots live side by side. A Spacer ambassador is found dead and detective Elijah Baley is assigned to find the killer. But with relations between the two cultures in the balance, the Spacers insist that he work with a partner of their choosing – a robot partner, R. Daneel Olivaw. Baley has never seen a robot like Daneel before – and soon, though the Three Laws of Robotics should render the crime impossible, Baley’s partner becomes his prime suspect.
