Black Knight of Berkeley

Ivan Duncan was a Berkeley High School history and coach. While out dancing, he suffered a brain aneurysm.

His best friend, Rich, was a software engineer who had been developing a computer chip to implant in the brain of Alzheimer's patients to restore their memory. The chip was not yet approved by the FDA.
But to save his's friend's life, Rich and his business partner Merle, a brain surgeon, use a clandestine operation to implant the chip in their friend's brain.

Premonitions find their way into Ivan's dreams, of murders that had not yet happened. Ivan decided to fight the evil he saw in the shadows of the night. He would become the Black Knight.
