Decent detective story. Gotta love scifi settings that have robots, laser guns, and planetary colonization, but no cellular phones, GPS, or surveillance cameras everywhere. That said, it was written in 1953--so we might forgive the good professor for failing to predict the course of certain technological trifles.
Reveals itself to be a gloss in the margin of Mary Shelley, insofar as Frankenstein
is a "Medieval novel describing a robot that turned on its creator" (168), which is an odd way to describe the story (I understood it to be a creator who turned on a robot).
Good start for what culminates with Foundation.
Recommended for medievalists, cerebroanalysts, and those with justice-desire circuits.
