A disturbingly successful string of thefts of ancient, religious artifacts from Catholic churches in the New England area has left police baffled. Then a priest gets a call from one of the thieves, offering the artifacts back for a considerable ransom. Acting as agents for the church, James MacBridan and the Hawthorne Group are called in by the archbishop to handle this most delicate situation. The thief and MacBridan meet, but they are not alone. Something else has been waiting for them, something dark and terrifying. The simple exchange ends violently, leaving MacBridan unconscious and the thief brutally murdered. Although many of the artifacts are recovered, MacBridan sets off to find the most important of the missing artifacts, the Cross of St. Patrick.MacBridan finds himself up against an enemy more ruthless, more deadly than he has ever faced before. The body count and the terror continue to rise the closer he gets, all in a place where no one is who they appear to be. In James Parker's The Dark Side of the Cross, MacBridan finds that in order to survive he will have to lean on a faith that he has long since cast aside.
