Harold Newman was a loser. He was a plodding bank clerk whose past was weary and whose future was dull. Until the moment when his mind was activated by a warp in time and he became a super brain - a brilliant freak gifted with the power of twenty computers. Suddenly Harold's future wasn't dull anymore. It was deadly.
