The exploits of Asimov's Detective Baily and his robot partner of expedience Daniel continue onto a unique planetary colony of Solaria where the population of humans is exponentially less than that of Robots. Given the sheer physical distances between humans on this world and the Three Laws protecting humans from any harm coming from a robot, a murder would be the last crime that could possibly be committed. Nonetheless, one has happened and while the act itself is shocking what Baily and Daniel discover about the outer colonies and space-born humans leads to larger issues that will affect the galaxy. While again the mystery takes a backseat to the Asimov world-building what really comes through as the focus is Baily's 'fish-out-of-water' narrative finding out about the strange isolated Solarian culture. Where 'viewing' people on monitors is far more preferable as the intimate act of physically 'seeing' someone, where geneticists have programmed humans for every job on the planet, and where complete trust is given to the robots. Asimov paints a cautionary tale of a future human society programmed and maintained to within every molecule, or so it seems because within every carefully calculated and curated system there are always unforeseen deviations and loopholes that can't be accounted for.
