The sound and the furry

When Chet and Bernie happen upon a prison work crew that includes Frenchie Boutette, an old criminal pal they sent up the river, getting a new case is the last thing they expect. But Frenchie, who comes from an old Louisiana family full of black sheep, needs help finding his one law-abiding relative, his brother Ralph, a reclusive inventor who has gone missing with his houseboat. Though he's tempted to take another job (with a big payday) in Alaska, Bernie decides to set course for the bayous of Louisiana, a trip that will introduce Chet to a world of sights, smells, and tastes that are like nothing he's ever encountered.
