Harry Benson is prone to violent, uncontrollable seizures and is under police guard after attacking two people.

Dr. Roger McPherson, head of the prestigious Neuropsychiatric Research Unit at University Hospital in Los Angeles, is convinced he can cure Benson through a procedure called Stage Three. During this highly specialized experimental surgery, electrodes will be place in the patient's brain, sending monitored, soothing pulses to its pleasure canyons.

Though the operation is a success, there is an unforseen development. Benson learns how to control the pulses and is increasing their frequency. He escapes — a homicidal maniac loose in the city — and nothing will stop his murderous rampages or impede his deadly agenda. . .

Michael Crichton, who died in Los Angeles on November 4, 2008, was a writer and filmmaker, best known as the author of Jurassic Park and the creator of ER. His most recent novel, Next, about genetics and law, was published in December 2006.

Crichton graduated summa cum laude from Harvard College, received his MD from Harvard Medical School, and was a postdoctoral fellow at the Salk Institute for Biological Studies, researching public policy with Jacob Bronowski. He taught courses in anthropology at Cambridge University and writing at MIT. Crichton's 2004 bestseller, State of Fear acknowledged the world was growing warmer, but challenged extreme anthropogenic warming scenarios. He predicted future warming at 0.8 degrees C. (His conclusions have been widely misstated.)

Crichton's interest in computer modeling went back forty years. His multiple-discriminant analysis of Egyptian crania, carried out on an IBM 7090 computer at Harvard, was published in the Papers of the Peabody Museum in 1966. His technical publications included a study of host factors in pituitary chromophobe adenoma, in Metabolism, and an essay on medical obfuscation in the New England Journal of Medicine.

Crichton's first bestseller, The Andromeda Strain was published while he was still a medical student. He later worked full time on film and writing. One of the most popular writers in the world, his books have been translated into thirty-six languages, and thirteen have been made into films.

He had a lifelong interest in computers. His feature film Westworld was the first to employ computer-generated special effects back in 1973. Crichton's pioneering use of computer programs for film production earned him a Technical Achievement Academy Award in 1995.

Crichton won an Emmy Award, a Peabody Award, and a Writers Guild of America Award for ER. In 2002, a newly discovered ankylosaur was named for him: Crichtonsaurus bohlini. He had a daughter, Taylor, and lived in Los Angeles. Crichton remarried in 2005.
