A man has the ability to unconsciously transform his own violent nature to his robots, making robots violent prone - including senseless murder & torture. Much of the story is about violent crimes of his android whose labor he has been living off on. There is a conclusion that this android behaves violently only when ambient temperature is about 90 F. Only, after this android's destruction in a police raid, his newer & simpler robot in a cold climate is also getting violent - thanks to master's mental effect.
