The Naked Sun is another story of Lije Bailey and R. Daneel Olivaw. Lije has been called up to solve a murder on Solaria, a world with a very sparse population, where even husband and wife interact as little as possible. Robots, on the other hand, are extremely numerous, and robotics is a major industry on Solaria.

Since under normal conditions, Solarians only view each other through trimensional screens, it is all but impossible for a murderer to have commited this crime. Yet the laws of robotics make it impossible for a robot to have been ordered to do the killing.

The victim's wife, Gladia, is the sole suspect, as the only human who could have possibly approached her husband in person. She tolerates physical presence better than others on her world, as Baily discovers, but she is still not comfortable.

The society presented is quite intriguing. The idea that humans can become so accustomed to virtual interaction that they cannot tolerate truly seeing each other seems somewhat more realistic in these days where people can meet people from all over the world, and some spend many, many hours every day doing so. Viewing is seen as so impersonal that people don't worry about what they wear when viewed, even though the image is so perfect it can almost be mistaken for reality.

Asimov in general was an exceptional author. The ending is perhaps the weakest point in the story; certainly not his best ending, but it certainly did not ruin the book as a whole.
