The Caves of Steel

A good, old-fashioned detective novel combined with Asimov’s sci-fi world building and with a background of a galaxy colonized by robots. As a murder mystery, it does well. It was tense and hard to put down—and the conclusion of the mystery and aligning of the clues was incredible. As a Robot novel, the robots were more a background device than a focus, and even Daneel just observed, used logic, and was feared—maybe that’s the point.
