Query: A wonderful science fiction classic

In "The Robots of Dawn," Asimov once again examines human nature through the devices of science fiction. The plot revolves around the "murder" of one of two humaniform robots in existence, which protagonist Elijah Baley is called to the Spacer home world Aurora to investigate. Asimov's characters and plot are deep, and his understanding of human nature is truly remarkable. This book is not only a very engaging work of science fiction and mystery, but also a shrewd exposition of the motives and prejudices of human beings. And yet Asimov manages to provoke in his readers a strong sense of hope for the future of humankind.
