In the year 2301, guns are only museum pieces and benign telepaths sweep the minds of the populace to detect crimes before they happen. In 2301 murder is virtually impossible, but one man is about to change that.
A group of idealistic immortals enlists the aid of Dr. Sequoya Guess, a Cherokee physicist, to take over Extro, the super computer that controls all mechanical activity on Earth, to rid the planet of all repression, but, instead, Extro gains control of Dr. Guess, who now must be eliminated. Reprint.
