Murder investigators Dunning and Briggs uncover a high-level plot to cripple Pettrolius, Texas, for voting in a petroleum workers’ union. More
Labor strife continues in Coastal Bend oil town Pettrolius, Texas, when union-busting sympathizer Elias Bryden is murdered, and a power-hungry district attorney indicts a mentally challenged school janitor for the murder.
In the ensuing investigation, newspaper reporter Glennis Dunning and Deputy Sheriff Jake Briggs uncover a plot launched out of the governor’s office to break the petroleum-workers’ union. Masterminded by local oil tycoon J.D. Strickland, the nefarious plan would, among other things, divert oil production tax revenues to county-seat Mayvale.
