Fire

What would you do if you learned the identity of "666"?
In prayer, a new believer, a professional investigator, offers his meager investigative abilities to God. From that point on he is inexorably drawn into a confrontation with the organized church of satan.
Asked to investigate the abduction and murder of a child, the investigator discovers - not a lone pervert, but a secret organization of satanists. From a nationwide rash of cattle mutilations and the murder of a Texas Ranger, the investigator begins a quest to expose and destroy the church of satan.
Fire is a true story.
