Synopsis
In a future where Earth's population lives in massive enclosed Cities — the 'caves of steel' — detective Elijah Baley is assigned to investigate the murder of a Spacer ambassador. His partner is R. Daneel Olivaw, a humanoid robot so advanced he is indistinguishable from a human.
The investigation forces Baley to confront his own anti-robot prejudice as he and Daneel form an unlikely partnership. The mystery also exposes the deep tensions between Earth's crowded, agoraphobic population and the wealthy, robot-dependent Spacer worlds.
