The classic thriller and "New York Times" bestseller is reissued with a new look. Prone to violent seizures, Harry Benson undergoes an experimental procedure that implants electrodes in his brain, sending soothing pulses to the brain`s pleasure canyon. However, Harry learns how to control the pulses and increase their frequency. Harry then escapes--a homicidal maniac loose in the city--and nothing will stop his murderous rampage.
