The thirst for truth can be murder… J. Mason Christopher, Vietnam veteran and Washington D.C. patent attorney, travels to Cold Water, Indiana, a church town where his daughter supposedly killed herself while investigating the town's recent rash of suicides. Christopher believes it was murder and determines to find the truth.
With the aid of his ‘Nam buddies and local businesswoman Lady McPherson, Christopher digs into the church’s control of the community, and learns that corrupt Pastor Kelly Baines is exploiting the town's water system. When Christopher’s team closes in, Pastor Baines counters his pursuers with increasing ruthlessness until the novel’s explosive end.
