While in Seattle, Frank collaborates with a man named Peter Watts and a shadowy organization known as the Millennium Group to hunt down serial killers and other pervasive evil possibly related to biblical prophecy. Group members [including Frank] were inoculated with a special virus so that their members could be protected from the ultimate plague. Frank later discovered the "Millennium group is not concerned with any single individual in life...our responsibility is with the whole of mankind." The group's real purpose was about control not salvation. They used Bible prophecy as a cover for their insane deeds.

After the Millennium Group engineered an ebola-like virus outbreak that killed Frank’s wife, he returned to Washington D.C. with his daughter, Jordon and bought a house in Falls Church, Virginia. He joined forces with the FBI’s Critical Incidents Response Group and old friend Asst. Dir. Andy MacLaren, and Agents Barry Baldwin [later killed] and Emma Hollis [who betrayed Frank by cutting a deal with the Millennium Group in exchange for a cure for her father’s Alzheimer disease]. Frank finally quit the FBI and started his own campaign against the Millennium Group. He is presently in hiding with his daughter.

Some Millennium-isms

Bob Bletcher:	What do you see?
Frank Black:	I see what the killer sees.
Bob Bletcher:	What, like a psychic?
Frank Black:	No. I put myself in his head. I become the thing we fear the most.
Bob Bletcher:	How?
Frank Black:	I become capability. I become the horror. What we know we can become only in our heart of darkness. It's my gift. It's my curse.

Frank Black: It is prophesied that when the end comes, it will come in darkness: a catastrophe all foresaw but few believed. Most of us will battle too late against the chaos, but not the few, the radical few, who obey no discipline. Unencumbered by conscience, they prepare ruthlessly pursuing their own preservation. If they survive, the rest of us perish.
