Naked Sun

I just finished a book called Naked Sun by Isaac Asimov.  It is the second in a series of books. I think it is the best so far of the series. In the book, a spacer is murdered on Saria, a planet. The head of security at the planet sends for Elijah Baley to come and investigate the case. Baley is again accompanied by his robot friend, Daneel. Together they figure out that the murderer was not the wife of the victim (every one thought she killed her husband) but the best robotist of all the colonized planets who killed the spacer. It was a shocking end of the book.  I thought it was a robot who did it. I liked this book because it is set in a future that is filled with robots who do some of the jobs that people don’t want to do.
