With Folded Hands...

Seemingly perfect robotic "Humanoids" appear in the town of Two Rivers and offer residents a life free of work, stress and danger. But at what cost? "With Folded Hands" follows Mr. Underhill, as the Humanoids threaten his household, destroy his android business and take control of the town in order to "Serve and Obey, and Guard Men from Harm."
A precursor to Williamson's novel THE HUMANOIDS, which Damon Knight called "without a doubt, one of the most important science-fantasy books of its decade."
