A Catholic bishop. A Quaker prayer leader. A Methodist minister. A Mormon ward leader. An entire congregation of Seventh Day Adventists. What do they have in common? They all minister to people's spiritual needs. And someone-or something-is ripping them to shreds for it. A BLOODY WARNING. Police detective Caldwell "Cal" Evans, still three weeks shy of completing rehab, is called in on the case. His only clue is a chilling message written in blood at the first murder scene: "Leave the Christ alone. He does not belong to you." THE SERPENT SHALL REIGN. With bodies piling up, Cal and his partner, Velvet Rabinowitz, chase leads involving snake-handling cults, the Dead Sea Scrolls, and an ancient ceremony left unfinished for two thousand years. With the help of a graduate student and an enigmatic Roman Catholic priest, the two detectives do more than fight for their lives.
