Science fiction and murder investigation: I love this combination. This is the second book of the Robots series and I read it 3 years after reading "The Caves of Steel". I am not sure why I took so long to start reading this one, but I not disappointed. It was a great contrast if compared to the first one where the detective Elijah Baley was investigating a murder case on Earth with underground cities and crowded spaces.

The Naked Sun takes place in an Outer World planet called Solaria which has only 20 thousand humans that live with 200 thousand robots. The culture, habits and taboos are completely different in Solaria, where humans are not used to seeing each other, instead, they socialize through "viewing", something resembling a uber high-tech-quality with immersion Skype talk. Like all good detective stories, there was no obvious motive, opportunity or weapon on the crime scene. There are many elements in the story that reminded of the classic Sherlock Holmes stories, which I love.

And above all the murder mystery the book brings interesting reflections and questions on the human need for robots, the limits of artificial intelligence and our values as human beings.
