If there's one thing the mighty Isaac Asimov excelled at, it was robots. Lots of robots.
So it isn't surprising that when Asimov wrote a trilogy of mysteries, they revolved around robots. And murder. Robots and murder together, whether as the victims or the suspected killers -- and this combination proved to be all the more compelling as Asimov sculpted an entire futuristic world where robots dwell among humans, domed cities dot the Earth, and the simple art of murder has been further complicated through robotics.
All three mysteries take place in a now-zeerusty future where the inhabitants of Earth live in enclosed city-domes, crammed in like so many sardines, with robot servants doing anything that needs to be done outside. There are many Spacer worlds such as Aurora (a free-love society) or Solaria (a place where physical proximity is considered unclean), which use their superior tech to make sure that Earth never expands outside its boundaries (even if they could manage to get outside their domes).
New York Cop Elijah Bailey is paired up with humaniform robot R. Daneel Olivaw, who possesses superior intelligence and looks almost exactly like a human. Despite Lije's dislike of robots, he and Daneel work well together, which is necessary to solve the bizarre, robot-centric murder mysteries that keep coming their way -- two Spacer scientists, and another humaniform robot. What's more, these crimes are more than simply one person killing another -- they are tied to complex political issues that could destroy Earth if Lije doesn't find the answers.
Though Isaac Asimov is best known for spinning tales of advanced intelligent robots, "The Robot Novels" relies just as heavily on political thrillers and whodunnits as it does on science fiction. In fact, he weaves together these three literary genres until they can't be separated -- each murder mystery is tied directly to the political strife and schemings on the various planets, and each murder also is tied deeply to the robots in some way. The catch is, robots are inherently programmed not to harm humans.
And through this, Asimov explores very alien ways of life -- the languid and stagnant Solaria, the cramped dark cities of Earth -- while also exploring the mistrust, fear, lack of logic, and ignorance that keep people apart. There's a lot of philosophical meditation in here, including musings on the nature of life and intelligence, and whether a robot like Daneel is truly "alive."
But Asimov is too skilled a writer to let these deeper themes bog down what is, essentially, a hard-boiled mystery/political thriller. The first two stories move along at a brisk, smooth pace, tying together the basic crime-solving methods with sci-fi issues (though robots are often implicated, they literally CAN'T commit murder). "Robots of Dawn" is a bit slower-moving, with many chapters that are a bit too meditative (Gladia gives us a blow-by-blow description of her life since she left Solaria).
Asimov also crafts the ultimate odd-couple cop duo -- Elijah Bailey is an old-fashioned cop with a quick but not infallible mind, living a formerly ordinary life until he becomes a sort of celebrity detective. What's more, he has his own biases and prejudices, but is open-minded enough to work past and despite them. Daneel makes up for Lije's shortcomings by being logical and unbiased, but he doesn't have Lije's imagination -- and he's a wonderfully endearing android sidekick.
"The Robot Novels" brings together a brilliant trilogy of futuristic murder mysteries -- lots of robots, mysterious deaths and planetary conspiracies. And of course, a cop duo at the center of it all.
