Cult is a 2003 novel by Warren Adler.
Barney Harrigan believes his life to be great. He has a well-paying job, a lovely young wife, Charlotte, and a five year old son, Kevin. He sees nothing wrong. But after his wife goes off to visit her sister, she soon decides she is not going to come back. She has discovered the Glories, a religious cult. She feels her life belongs with them and won’t return to her family.
Barney feels that they have captured and brainwashed her. He cannot accept that she willingly joined this cult. He contacts Naomi Forman, an old flame with connections in Washington, D.C., with hopes that she may be able to help get his wife back. He is not satisfied when he learns that the Glories are officially recognized as a religion and little can be done unless there is physical proof his wife is being held against her will.
Barney hopes he can get her away from the cult long enough to have her deprogrammed. He concocts a plan involving their child, thinking he can draw Charlotte out with a promise of handing over their son, then kidnap her and let the deprogramming begin. What he does not count on and does not expect, is Charlotte’s death. It’s labeled a drowning, she slipped into the river and died. Barney believes otherwise. He feels the cult killed her.
Kidnaping Charlotte’s sister and another member of the cult, Barney has a hired hand attempt to deprogram them and force a confession. While occupied with this act, Barney’s attention is taken away from his son, who is kidnapped by the Glories. They want to exchange the son for their two members. The prospect of losing his son along with his wife sends Barney over the edge and he returns to the cult’s base, not with its members, but with a loaded machine gun.
The other strong theme depicted is the notion that you do not need to be a part of a cult to do bad things. Barney is ready to kill for what he wants. He has no religious affiliation, but over the course of the novel, he is shown to be no different than the forces he claims are destroying his family. He chastises cults for their violent behavior, but when his world is threatened, he is quick to pick up a gun. The distinction between himself and the cult leaders is no longer as clear as it once was.
