The Robots of Dawn

Detective Elijah Baley of Earth is training with his son and others to overcome their socially ingrained agoraphobia when he is told that the Spacer world of Aurora has requested him to investigate a crime: the destruction of the mind of R. Jander Panell, a humaniform robot identical to R. Daneel Olivaw, with a mental block. The robot's inventor, Han Fastolfe, has admitted that he is the only person with the skill to have done this, but denies having done it. Fastolfe is also a prominent member of the Auroran political faction that favors Earth; wherefore, it is politically expedient that he be exonerated. En route to Aurora, Baley again is partnered with R. Daneel Olivaw, and introduced to R. Giskard Reventlov, a robot of an earlier model.
