"A hunt for the one law-abiding brother in a family of black sheep sets Chet and Bernie on a course for Louisiana, a trip that will introduce Chet to a world of sights, smells, and tastes unlike any other. In bayou country, it appears that the disappearance of reclusive Ralph Boutette resulted from a dispute over stolen shrimp between his no-good family and their enemies, the maybe-even-worse Robideaus--until Chet digs up a buried clue that points to Big Oil and an impending environmental catastrophe. Soon Chet and Bernie are fighting off shadowy black ops figures, a violent biker gang, and Iko--a legendary bayou gator with a seemingly insatiable appetite. Meanwhile, deep under the Gulf, the pressure just keeps building."--Page 4 of cover.
